Twelve signs and symptoms of low testosterone

Emergency 101

At what point does a fever or stomachache become a medical emergency? If you slice your finger with a knife, or you are having the worst headache you’ve ever had, should you seek emergency care? How do you know?

The following is advice for how to handle common emergency medical conditions. This section does not contain all the signs or symptoms of medical emergencies, and the advice is not intended to be a substitute for consulting with a medical professional. If you think you are experiencing a medical emergency, seek immediate medical attention.

Abdominal or belly pain can have many causes. It may be due to food poisoning, an intestinal or gall bladder obstruction, an infection or inflammation. It could also be appendicitis, a kidney stone or peptic ulcer disease.

Many drugs cause side effects, and certain medicines can trigger life threatening reactions allergic and non allergic in some people. Some medicines also interact with other medications and cause adverse drug reactions.

Anaphylaxis is a severe, life threatening, multisystemic allergic reaction that is triggered by common substances, such as foods, insect stings, medications and latex.

Although asthma and allergies are two separate conditions asthma is a chronic disease of the bronchial airtubes, whereas allergies involve an overreaction of the body’s disease fighting immune system the two conditions can be intertwined and often overlap.

Acute back problems may be experienced by almost everyone at some point in their lives. There are many causes of back pain, including accidents, muscle strains, sports injuries; acquired nerve, disc or muscle disorders; mechanical problems involving the spine; and infections and tumors.

Most bites and stings are easily treatable and non threatening. However, some insects, snakes, jellyfish and even humans can bite or break the skin and potentially introduce disease into your body.

Broken bones (also called fractures) are a common injury for adults and children. They may be caused by falls, motor vehicle crashes, direct blows and even intentional injuries, such as violence and child abuse.

About 4,000 people die each year in the United States from fire and burn injuries. Burns are one of the leading causes of childhood injury. They can be caused by scalding from hot liquids or cooking oils, contact with flames, or from overexposure to the sun.

Emergency physicians used a patient’s personal activity tracker and smartphone to identify the time his heart arrhythmia started, which allowed them to treat his new-onset atrial fibrillation with electrical cardioversion and discharge him home.

The recent and sudden deaths of several well-known celebrities from heart-related issues should focus everyone’s attention on the dangers of heart disease and knowing the symptoms of a serious problem.

ACEP recommends that the Heimlich Maneuver be employed only when a person is choking and his or her life is endangered by a windpipe obstruction.

Most cuts are minor, but it’s still important to care for them. Most can be treated by cleaning with soap and water and applying a clean bandage.

It is estimated that more than 20 million people in the United States have diabetes, with an estimated six million people being unaware they have it.

Earaches and ear infections can have a variety of causes – viral, bacterial and fungal – and can affect different parts of the ear.

Causes of electrical injury and shock include accidental exposure to household or appliance wiring, arcs from power lines, the severing of an electrical cord or sticking of foreign objects into an outlet (typically in the case of a young child).

Eye wounds and emergencies can include cuts and scratches, traumatic injuries from foreign objects, burns and chemical exposure (e.g., cleaning solutions, garden chemicals). Any of these conditions can potentially lead to vision loss if left untreated. Always wear eye protection.

Fainting is a loss of consciousness caused when the blood supply to the brain is momentarily interrupted. While typically sudden and alarming, it usually is not harmful (unless the person suffers fainting related injuries), and consciousness is typically regained quickly.

Fever by itself is not an illness, but a symptom for a range of medical conditions. It also can be a side effect of some medications. Fever is one of the most common reasons that parents visit an emergency department with a child.

In the United States approximately 10,000 people die each year from food poisoning, and many more become ill and require medical attention.

Young children, especially those under age five, sometimes put items, such as marbles, beads, dried beans, tiny button-shaped batteries or small toys in their ears, noses and mouths. It’s important to seek immediate medical attention to remove them, if they are not easily removable.

Head injuries can be caused by falls, motor vehicle crashes and even violence. It’s important to prevent injuries by buckling your seat belt in your car and wearing safety equipment, such as helmets, while biking or playing sports.

Headaches have a variety of causes. Some are caused by stress and muscle tension, while others may be caused by lack of sleep, a delayed meal, an injury or even foods (e.g., lack of caffeine, alcohol, chocolate, cheeses, nuts, food).

Heat related illness can be caused by overexposure to the sun or any situation that involves extreme heat. Young children and the elderly are most at risk, but anyone can be affected.

Hypothermia is a potentially life-threatening condition caused by overexposure to cold air or cold water. Although most people typically are not at risk of developing hypothermia, the condition can strike anyone, depending on their individual circumstances, weather conditions and level of exposure in a cold or wet environment.

Medical emergencies can be frightening and stressful. But knowing what to do in an emergency can help you effectively deal with the situation. Here you can find information about emergencies.

UV Exposure: Why Do We Ignore the Health Risks?

Published Thursday 17 July 2014

By Honor Whiteman

The sun is shining, so what are your plans? For many of us, the answer will be to hit the beach and soak up the rays. But while you are busy packing beachwear and towels, are you considering the dangers of sun exposure?

Exposure to ultraviolet (UV) radiation – from the sun, tanning beds, lamps or booths – is the main cause of skin cancer, accounting for around 86% of non-melanoma and 90% of melanoma skin cancers. In addition, excessive UV exposure can increase the risk of eye diseases, such as cataract and eye cancers.

The health risks associated with exposure to UV radiation have certainly been well documented, so much so that the World Health Organization (WHO) have now officially classed UV radiation as a human carcinogen.

This year alone, Medical News Today reported on an array of studies warning of UV exposure risks. One study, published in the journal Pediatrics, revealed that tanning bed use among youths can increase the risk of early skin cancer, while other research found that multiple sunburns as an adolescent can increase melanoma risk by 80%.

Furthermore, in response to reported health risks, the Food and Drug Administration (FDA) recently changed their regulation of tanning beds, lamps and booths. Such products must now carry a visible, black-box warning stating that they should not be used by anyone under the age of 18.

How does UV radiation cause damage?

UV radiation consists of three different wavebands: UVA, UVB and UVC. The UVC waveband is the highest-energy UV but has the shortest wavelength, meaning it does not reach the earth’s surface and does not cause skin damage to humans.

However, UVA has a long wavelength and accounts for 95% of solar UV radiation that reaches the earth’s surface, while UVB – with a middle-range wavelength – accounts for the remainder. Tanning beds and tanning lamps primarily emit UVA radiation, sometimes at doses up to 12 times higher than that of the sun.

Both UVA and UVB radiation can damage the skin by penetrating its layers and destroying cellular DNA. UVA radiation tends to penetrate deeper layers of skin, known as the dermis, aging the skin cells and causing wrinkles. UVB radiation is the main cause of skin reddening or sunburn, as it damages the outer layers of the skin, known as the epidermis.

Excessive UV exposure can cause genetic mutations that can lead to the development of skin cancer. The browning of the skin, or a tan, is the skin’s way of trying to stop further DNA damage from occurring.

Of course, it is not only the skin that can be subject to damage from UV radiation. Bright sunlight can penetrate the eye’s surfaces tissues, as well as the cornea and the lens.

Ignoring the risks of UV exposure

But regardless of the numerous studies and health warnings associated with UV exposure, it seems many of us refuse to take note.

A 2012 survey from the Centers for Disease Control and Prevention (CDC) found that 50.1% of all adults and 65.6% of white adults ages 18-29 reported suffering sunburn in the past 12 months, indicating that sun protection measures are not followed correctly, if at all.

A more recent study from the University of California-San Francisco stated that the popularity of indoor tanning is “alarming” – particularly among young people.

The study revealed that 35% of adults had been exposed to indoor tanning, with 14% reporting tanning bed use in the past year. Even more of a concern was that 43% of university students and 18% of adolescents reported using tanning beds in the past year.

Overall rates of tanning bed use, the researchers estimate, may lead to an additional 450,000 non-melanoma and 10,000 melanoma skin cancer cases every year.

It seems unbelievable that so many of us are willing to put our health at risk to soak up some sunshine. So why do we do it?

The desire for a ‘healthy tan’

A recent study published in the journal Cell suggested that UV radiation causes the body to release endorphins – “feel-good” hormones – which makes sun exposure addictive.

But Tim Turnham, executive director of the Melanoma Research Foundation, told Medical News Today that many people simply favor a tanned body over health:

“Despite elevated awareness of the dangers of UV radiation, people still choose to ignore the dangers in the pursuit of what they consider to be a ‘healthy tan.’ This is particularly an issue among young people who tend to ignore health risks in favor of enhancing their social status and popularity. We know that tanning appeals to people who are interested in being included, and this is a primary driver for teens – being part of the ‘in’ crowd.”

Anita Blankenship, health communication specialist at the CDC, told us that the desire for a tan is particularly common among young women.

“In the US, nearly 1 in 3 young white women ages 16-25 years engages in indoor tanning each year,” she said. “These young women may experience pressure to conform to beauty standards, and young people may not be as concerned about health risks.”

Turnham agreed, telling us that the indoor tanning industry specifically targets this population. “Aggressive marketing, deep discount and package deals are used routinely by tanning salons, who market their services preferentially to young women,” he said.

Blankenship added that the public are also presented with “conflicting messages” when it comes to the safety of excess UV exposure. She pointed out that a recent US report found that only 7% of tanning salons reported any harmful effects from tanning beds, booths or lamps, while 78% reported health benefits.

“It is important to monitor deceptive health and safety claims about UV exposure, as they may make it difficult for consumers to adequately assess risk,” she told us. “It is important for people to understand that tanned skin is damaged skin, and that damage can lead to wrinkles and early aging of the skin, as well as skin cancer including melanoma – the kind of skin cancer that leads to the most deaths.”

Progress has been made, but more needs to be done

This month is UV Safety Month – an annual campaign that aims to increase public awareness of the health implications caused by UV exposure.

With the help of such campaigns and an increase in studies detailing UV risks, many health care professionals believe there has been a change for the better in attitudes toward UV exposure.

Many health care professionals believe much progress has been made in increasing awareness of UV exposure risks in recent years, but more needs to be done.

“Certainly the scientific community, a number of federal agencies, and possibly the general public are more aware of the risk of UV exposure,” a spokesperson from the National Cancer Institute (NCI) told Medical News Today.

“Action and more coordinated efforts increased markedly about 4 years ago, when a number of epidemiological studies documented the harms of indoor tanning, the FDA held their scientific advisory committee meeting to discuss need for changing indoor tanning device regulations, and they also acted on their previous proposals to change sunscreen regulations.”

The spokesperson continued:

“We think these summaries acted as a catalyst for efforts to make the public and policy makers aware of the risks of indoor tanning, and also they gave a boost to efforts to increase awareness of outdoor sun exposure risks and encourage sun safe protective behaviors.”

In addition, some studies have indicated that many youngsters may even be moving away from the use of tanning beds. A recent Youth Risk Behavior Survey found that among high school students, indoor tanning activity decreased from 15.6% in 2009 to 12.8% in 2013.

Turnham told us that since sunless tanning – such as the use of spray tans – is on the increase, it may be that youngsters are using this as an alternative to tanning salons. But the NCI spokesperson said such an association needs to be investigated before any conclusions can be reached:

“We do not know if changes in indoor tanning are related to increases in use of spray-on and sunless tanning products and services,” they told us. “Some studies indicate that sunless products and services are used by people who continue to engage in indoor tanning, but it is an area we continue to research. We are hopeful that we will be able to measure this in an upcoming national survey supplement that is being developed by NCI and CDC.”

But despite widespread efforts to increase UV safety awareness, Turnham believes there is still a lot more that can be done to protect public health:

“Regulators could and should do much more to fight the ravages of UV exposure. We need federal legislation banning the use of tanning beds by minors. We need more funding for awareness and prevention efforts.”

He added that doctors can also play a role in increasing UV exposure awareness by warning patients of associated risks – something the US Preventive Services Task Force (USPSTF) recommend. They state that health care providers should counsel fair-skinned youths between the ages of 10 and 24 about the risks of indoor tanning and how to protect themselves against UV radiation from the sun.

However, Turnham noted that doctors do not have much time with each patient and proposes that signage in waiting areas warning of the risks of UV exposure may also be effective.

Protecting against UV radiation

Whether there will be further regulation for indoor tanning or an increase in awareness efforts is unclear. But one thing is certain: we can help ourselves to avoid the negative health implications associated with UV exposure.

The American Cancer Society notes young children need extra protection from the sun, as they spend more time outside and can burn easily.

The CDC recommend the following for protecting against UV radiation:

  • Stay in the shade if possible, particularly when the sun is at its strongest – usually around midday
  • Wear clothing that covers your arms and legs
  • Wear a wide-brimmed hat that provides shade for your head, face, ears and neck
  • Wear wrap-around sunglasses that protect against both UVA and UVB radiation
  • Use sunscreen with a minimum sun protection factor (SPF) of 15 that protects against UVA and UVB radiation, and reapply every 2 hours
  • Avoid indoor tanning.

In addition, the American Cancer Society notes young children need extra protection from the sun as they spend more time outside and can burn easily. They add that babies younger than 6 months should be kept out of direct sunlight and be covered with protective clothing. Sunscreen should never be used on an infants skin.

As  we embark on the glorious, sunny days of the summer season and enter into the Fourth of July Celebration, let’s do all we can to protect ourselves and our little ones from UV rays’ potential threats to our skin. Remember, UV rays are the major causes of several deadly skin cancers and sunscreen is one of the most easy and accessible ways to protect against them. So, get out those sunscreen tubes and cover your head with a hat and your eyes with some shades because sun protection is trending today and everyday!

Genes linked with sunburn, skin cancer risk

May 8, 2018

Certain genes can determine which people are more at risk of getting sunburn and possibly develop skin cancer as a result..

In a trawl of the genetics of nearly 180,000 people of European ancestry in Britain, Australia, the Netherlands and United States, researchers found 20 sunburn genes.

Eight of the genes had been associated with skin cancer in previous research, according to findings published in the journal Nature Communications.

And in at least one region of the genome, “we have found evidence to suggest that the gene involved in melanoma risk… acts through increasing susceptibility to sunburns,” co-author Mario Falchi of King’s College London told AFP.

Sun exposure is critical for the body’s production of vitamin D, which keeps bones, teeth, and muscles healthy, and which scientists say may help stave off chronic diseases, even cancer.

But too much can be painful in the short-term, and dangerous for your health.

The new study, which claims to be the largest to date into the genetics of sunburn, helps explain why people with the same skin tone can have such different reactions to exposure to sunlight—some burn red while others tan brown.

It may also begin to explain factors in skin cancer risk.
“It is necessary to explore these genes in more detail, to understand the mechanism by which they contribute to propensity to burn,” said Falchi.

In future, the research may help identify people at risk, through genetic testing.

“People tend to ‘forget’ that sunburns are quite dangerous,” said Falchi.

“Given the rise in incidence in skin cancer, we hope that knowing there is a genetic link between sunburn and skin cancer may help in encouraging people to lead a healthy lifestyle.”

Millennials aren’t getting the message about sun safety and the dangers of tanning

Many millennials lack knowledge about the importance of sunscreen and continue to tan outdoors in part because of low self-esteem and high rates of narcissism that fuel addictive tanning behavior, a new study from Oregon State University-Cascades has found.

Lead author Amy Watson and her colleagues found that those with higher levels of self-esteem were less likely to tan, while those with lower self-esteem and higher levels of narcissism were more likely to present addictive tanning behavior. The motivation for the addictive tanning behavior was the perception of improved appearance.

“This study gives us a clearer understanding of actual consumer behavior,” said Watson, an assistant professor of marketing at OSU-Cascades. “The number of people still deliberately exposing their skin to the sun for tanning purposes is alarming. We need to find new ways to entice people to protect their skin, including challenging the ideal of tan skin as a standard of beauty.”

The findings were published recently in the Journal of Consumer Affairs. Co-authors are Gail Zank and Anna M. Turri of Texas State University.

Skin cancer is the most common type of cancer worldwide, with more than 3.5 million cases diagnosed annually. Melanoma cases among women rose sharply between 1970 and 2009, with an 800 percent increase among women 18 to 39.

In an effort to improve consumer education about the role of sunscreen in the prevention of skin cancer, the Centers for Disease Control and the Food and Drug Administration developed a new “Drug Facts” panel of information now required on all sunscreen bottles. The panel includes directions for sunscreen use and advice on other sun protection measures, among other information.

The researchers’ goal with the study was to gauge whether the information on this new label is effective at curbing tanning behavior and if new information is helping to increase consumer knowledge about how and when to use sunscreen and how much to use.

The study of 250 college students, most between 18 and 23 years old, measured their sun safety knowledge and included: questions about their beliefs regarding sunscreen effectiveness and ultraviolet light exposure danger; questions about tanning motivation and behavior; an assessment of tanning addiction; and personality questions relating to self-esteem, narcissism, appearance and addictive behavior.

The study participants, 47 percent male and 53 percent female, scored an average of 54 percent on an 11-question sun safety knowledge test, which included true/false statements such as: “On a daily basis I should use at least one ounce of sunscreen on exposed skin” (true); and “When applied correctly, SPF 100 is twice as effective as SPF 50” (false).

About 70 percent of the study participants reported purposefully exposing their skin to the sun to achieve a tan. About a third of the participants reported that having a tan is important to them, while about 37 percent said they feel better with a tan, and 41 percent indicated that having a tan makes them more confident in their appearance

The participants’ levels of tanning addiction were measured through questions such as “I get annoyed when people tell me not to tan,” and “I continue to tan knowing that it is bad for me,” and “I feel unattractive or anxious to tan if I do not maintain my tan.”

The researchers found that those with lower self-esteem and higher narcissism rates were also more likely to exhibit addictive tanning behavior. They found no evidence that increased knowledge about sun safety leads to lower levels of addictive tanning.

“What we found is that this knowledge doesn’t matter to the consumers,” Watson said. “That tactic to require sunscreen manufacturers to include this information is not effective.”

Sun safety and sunscreen messaging from the CDC is all statistics-based, emphasizing the likelihood of a skin cancer occurrence or diagnosis, Watson said. But that type of message isn’t resonating with millennials. The next step for Watson and her colleagues is to begin testing other types of messages to identify ways millennials would respond more positively to sun safety measures.

“People are starting to get the message about the dangers of using tanning beds, but a large number of people are still tanning outdoors, deliberately exposing their skin to the sun, because they think it’s attractive,” she said.

“We need to move away from the narrative where tan skin is associated with health and youth. That’s the opposite of reality. Because reality is tan skin is damaged skin.”

Happiness Goes Viral

What is it about laughter that’s contagious? Sometimes you just can’t stop from smiling when you hear or see it. Last September, an elderly couple from Iowa infused the internet with laughter and joy. Their random act of happiness at Mayo Clinic hit You Tube and made more than 6 million people smile. And that, say Francis and Marlow Cowan, is what keeps them young.

The Often Misunderstood Diagnosis of Post-Traumatic Stress Disorder

PTSD stands for Post-Traumatic Stress Disorder and is a condition that many veterans and non-veterans alike suffer; PTSD can occur when someone experiences or witnesses a traumatic event. This condition wasn’t always understood properly by the medical or military community, and Department of Defense press releases often point to earlier attempts to identify PTSD symptoms in the wake of service in World War 2, Vietnam, and other conflicts.

PTSD Awareness Day is observed today, Wednesday, June 27, 2018.

The History of PTSD Awareness Day

In 2010, Senator Kent Conrad pushed to get official recognition of PTSD via a “day of awareness” in tribute to a North Dakota National Guard member who took his life following two tours in Iraq.

Staff Sergeant Joe Biel died in 2007 after suffering from PTSD; Biel committed suicide after his return from duty to his home state. SSgt. Biel’s birthday, June 27, was selected as the official PTSD Awareness Day, now observed every year.

How Do People Observe Post-Traumatic Stress Disorder Awareness Day?

Much of what is done to observe PTSD Awareness Day involves encouraging open talk about PTSD, its’ causes, symptoms, and most important of all, getting help for the condition. When today, PTSD is often misunderstood by those lacking firsthand experience with the condition or those who suffer from it. PTSD Awareness Day is designed to help change that.

The Department of Defense publishes circulars, articles, and other materials to help educate and inform military members and their families about the condition. The Department of Veterans Affairs official site has several pages dedicated to PTSD, and when military members retiring or separating from the service fill out VA claim forms for service-connected injuries, illnesses, or disabilities, there is an option to be evaluated for PTSD as a part of the VA claims process.

What Is Post-Traumatic Stress Disorder?

The current American Psychiatric Association’s Diagnostic and Statistical Manual, DSM-IV, says PTSD can develop through a range of exposures to death or injury: direct personal involvement, witnessing it or, if it concerns someone close, just learning about it.  Post-traumatic stress disorder is a form of anxiety that can happen after experiencing or witnessing actual or near death, serious injury, war-related violence, terrorism or sexual violence.  While most people typically connect this disorder to military veterans or refugees, it can happen to anyone.

Almost no other psychiatric diagnosis has generated as much controversy.  The diagnosis is almost four decades old.  PTSD is not a sign of weakness, and people can be affected by PTSD even when they were not directly part of the traumatic event.

The specific nature of the trauma can and does vary greatly. Experts are quick to point out, while combat and combat-related military service can be incredibly challenging, and while witnessing or being a victim of an event that rips the fabric of daily life can be traumatic, not everyone responds the same way. Some may develop symptoms of PTSD, while others may be unaffected.

Post-Traumatic Stress Disorder: How Widespread Is It?

Some sources estimate that as many as 70% of all Americans have experienced a traumatic event sufficient to cause PTSD or PTSD-like symptoms. That does not mean that all 70% of Americans WILL suffer from PTSD. Using these statistics, some 224 million Americans have experienced a traumatic event. Of that number, some 20% will develop PTSD symptoms, roughly 44 million people.

Of that 44 million, an estimated eight percent experience active PTSD symptoms at any one time. An estimated 50% of all mental health patients are also diagnosed with Post-Traumatic Stress Disorder.

PTSD: Often Misunderstood and Misidentified

“Shell shock” and “combat shock” were earlier attempts to define and understand the symptoms of PTSD. Post-traumatic stress disorder was often stigmatized in popular culture after the Vietnam conflict, and many films and television shows featured antagonists or unsympathetic characters suffering from “Vietnam flashbacks” or other issues.

The misunderstanding of PTSD slowly began to change in 1980 when it was recognized as a specific condition with identifiable symptoms. It was then the disorder was listed in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM).

This manual is a diagnostic tool for mental health professionals and paraprofessional workers in the healthcare field and is considered a definitive reference. The addition of PTSD to the DSM was a highly significant development.

Today, the symptoms of Post Traumatic Stress Disorder are better understood, treatable, and recognized by the Department of Veterans Affairs as a service-connected condition. PTSD is not exclusive to veterans or currently serving members of the United States military, but a portion of those who serve are definitely at risk for PTSD.

What Are the Symptoms of Post-Traumatic Stress Syndrome?

Some PTSD symptoms may seem vague and non-specific, others are more readily identified specifically as evidence of PTSD. In this context “non-specific” means that the symptoms may be related to other mental health issues and not specifically limited to Post-Traumatic Stress Disorder.

In the same way, more “specific” symptoms may be manifest outside PTSD, but when looking for specific signifiers, these issues are common “red flags” that indicate PTSD may be the cause of the suffering rather than a different condition. This is often circumstantial, and there is no one-size-fits-all diagnosis for the condition.

Suicidal thoughts or self-destructive acts are often a result of PTSD or related symptoms. Anyone experiencing thoughts or urges to self-harm should seek immediate care to prevent the condition from getting worse in the short-term. (See below)

That said, more non-specific symptoms include varying degrees of irritability, depression, and suicidal feelings. More specific problems-especially where veterans and currently serving military members are concerned-include something known as “hypervigilance” or “hyperarousal”.

Other symptoms include repeatedly experiencing the traumatic event(s) in the form of flashbacks, nightmares, persistent memories of the event(s), and intrusive thoughts about the traumatic event(s).

These symptoms vary in intensity depending on the individual and are not ‘standardized”. They may come and go, or they may be persistent over a span of time. Sometimes PTSD sufferers can be high-functioning, other times they may be more debilitated by the condition.

Get Treatment For PTSD

Those who experience symptoms of PTSD or PTSD-like issues should seek help immediately. Department of Veterans Affairs medical facilities, private care providers, counselors, and therapists can all be helpful in establishing an initial care regimen or refer those suffering from PTSD to a qualified care provider.

The Department of Veterans Affairs has more information on help for PTSD on its’ official site including help finding a therapist.

Those experiencing suicidal feelings or self-destructive urges should get help immediately. The Suicide Crisis Hotline (1-800-273-8255) has a specific resource for veterans and the Department of Veterans Affairs offers a Veterans’ Crisis Hotline confidential chat resource.

Forgiveness Fills Life with Research Proven Health Benefits

Maybe you are considering forgiveness for yourself or others, but you’re not sure it’s worth the emotional effort. You might prefer to ignore the painful memories, stuff it down and keep going about your daily affairs. You will just deal with it later, right?

To forgive, whether yourself or others, and to be forgiven, brings relief beyond just the emotional or even spiritual, if you at a person of faith.  Today is Forgiveness Day – one of many observed throughout the year.  The original was established as International Forgiveness Day in response to a call to set aside old differences made by Desmond Tutu.  There is also Global Forgiveness Day next Saturday, and National Forgiveness Day in October.  All have one purpose – to encourage us to set things right; and there are great health benefits to doing so!

Whether it’s a bout with your boss, a feud with a family member or friend, or a spat with your spouse, unresolved conflict can go deeper than you may realize—it may be affecting your physical health. Not forgiving has its costs. When we harbor grudges and grievances, we retain everything that goes with them: anxiety, irritability, anger, and depression.  We may suffer insomnia, experience weight gain or loss, endure depletion of trust in ourselves and others, get caught up in numbing addictions and get stuck in a nerve fraying fight-or-flight mode.

The list is long and disabling.  The good news: Studies have found the act of forgiveness can pay huge dividends for your health, And research points to an increase in the forgiveness-health connection as you age.

What are the health benefits of forgiveness?

In a study at Virginia Commonwealth University, researchers sought to prove what many might already feel is common sense. They wrote, “Chronic unforgiveness causes stress. Every time people think of their transgressor, their body responds. Decreasing your unforgiveness cuts down your health risk. Now, if you can forgive, that can actually strengthen your immune system.” [1]

Dr. Bernie Siegel, author, surgeon and retired medical professor at Yale University, said, “I have collected 57 extremely well-documented so-called cancer miracles. At a certain particular moment in time, they decided that the anger and the depression were probably not the best way to go, since they had such little time left.

And so, they went from that to being loving, caring, no longer angry, no longer depressed, and able to talk to the people they loved. These 57 people had the same pattern. They gave up—totally—their anger, and they gave up—totally—their depression, by specifically a decision to do so. And at that point, the tumors started to shrink.” [2]

Medical researchers have become increasingly interested in studying the effects of forgiveness as a healing process. Evidence is mounting:  holding onto painful memories and bitterness results in long-term health problems. Forgiveness, on the other hand, offers numerous benefits, including:

  1. Lower blood pressure

When we no longer feel anxiety or anger because of past grievances, our heart rate evens out and our blood pressure drops. This normalizes many processes in the body and brings us our heart and circulatory system into stability.

  1. Stress reduction

Forgiveness eases stress because we no longer recycle thoughts (both consciously and subconsciously) that cause psychic stress to arise. By offering our burdens for healing, we learn how to leave irritation and stress behind.

  1.  Less hostility

By its very nature, forgiveness asks us to let go of hostility toward ourselves and others.  Spontaneous hostile behavior, like road rage and picking a fight for no reason, diminishes as our commitment to forgiveness goes up.

  1. Better anger-management skills

With fewer and fewer burdens from the past weighing us down, we have more self-control when we do get angry. We’ll be better able to take some breaths, count to ten, take a time-out or get some exercise—rather than strike out or lash out in anger.

  1. Lower heart rate

Forgiveness relaxes our hearts –  pain will ease out of our system. Our hearts calm down, and our heart rate decreases as a result.

  1. Lower risk of alcohol or substance abuse

This is a big one – possibly the biggest and best reason to jump into a forgiveness practice without delay. Substance abuse is a mask for underlying pain. Forgiveness helps release that pain and find the gifts in our situation instead.

  1. Fewer depression symptoms

Similar to lowering substance abuse, this is a crucial issue with retained anguish. Depression is debilitating and can lead to suicide. On the other hand, forgiveness gives us healing and can leave room to replace depression with a sense of purpose and compassion.

  1. Fewer anxiety symptoms

Almost everyone needs to forgive him or herself as well as others. Anxiety often arises when we fear we’ve done something wrong. Our guilty conscience causes tension at a deep level. Forgiveness helps us to love ourselves deeply, relieving inner pain.

  1. Reduction in chronic pain

Physical pain often has psychological underpinnings. When we allow a profound shift to happen with forgiveness, we heal ourselves on both psychological and physical levels. Thus, chronic pain can be reversed, and we can be restored to best health.

  1. More friendships

When we’re no longer holding grudges, we can get a lot closer to friends and family. Old relationships have a chance to change and grow, and new relationships can enter—all because we made room for them with forgiveness.

  1. Healthier relationships

When we make forgiveness a regular part of our emotional practice, we start to notice all of our relationships begin to blossom. There’s far less drama to deal with, and that’s a huge bonus.

  1. Improved psychological well-being

A good life, full of quality relationships, service to others and fun, is something that most of us hope for without ever knowing how to create it.  By releasing our grievances, we become more harmonious on all levels. Nightmares recede, and exciting new life visions become commonplace. We feel calmer, happier and ready to give compassion and love to the world.

  1. Enhanced immune function

Forgiveness lowers cortisol – a steroid hormone produced in response to stress that causes weight gain – and boosts immune function. You’ll feel more relaxed and centered, and you won’t get sick as easily once you’ve let go for good through forgiveness.

Looking at the list, it’s easy to see that if you had lower stress, hostility, blood pressure and chronic pain, you’d be far healthier for it. Also, if you had better relationships, improved psychological well-being and greater emotional connection, you could be living a life of joy and purpose.

Can You Learn to Be More Forgiving?

Now, look at this list below to see if you would enjoy improvements in any of these areas of your life:

  • Your Physical Health
  • Relationships with Loved Ones (Lovers, Spouse, Exes, and Friends)
  • Family Issues with Parents, Siblings and Children
  • Trauma from Childhood
  • Impacts of Racism, Sexism and Other “Isms”
  • Money Worries
  • Sexual Issues
  • Blocked Creativity

Forgiveness is not just about saying the words. It is an active process in which you make a conscious decision to let go of negative feelings whether deserved or not. As you release anger, resentment and hostility, you make room for empathy, compassion and sometimes even affection for the person who wronged you.

Studies have found some people are just naturally more forgiving. Consequently, they tend to be more satisfied with their lives and to have less depression, anxiety, stress, anger and hostility. People who hang on to grudges, however, are more likely to experience severe depression and even post-traumatic stress disorder, as well as other health issues described earlier. But that doesn’t mean they can’t train themselves to act in healthier ways. 62 percent of American adults say they need more forgiveness in their personal lives, according to a survey by the nonprofit Fetzer Institute.

Making Forgiveness Part of Your Life

Forgiveness is a choice.  You are choosing to offer compassion and empathy to the person who wronged you.  The following steps can help you develop a more forgiving attitude—and benefit from better emotional and physical health.

Reflect and remember.

That includes the events themselves, and also how you reacted, how you felt, and how the anger and hurt have affected you since.

Empathize with the other person.

For instance, if your spouse grew up in an alcoholic family, then anger when you have too much to drink might be understandable.

Forgive deeply.

Simply forgiving someone because you think you have no other alternative or because you think your faith requires it may be enough to bring some healing, but one study found people whose forgiveness came in part from understanding no one is perfect were able to resume a normal relationship with the other person.  This was true even if that person never apologized. Those who only forgave in an effort to salvage the relationship typically wound up with a worse relationship.

Let go of expectations.

An apology may not change your relationship with the other person or elicit an apology from them. If you don’t expect either, you won’t be disappointed.

Decide to forgive.

Once you make that choice, seal it with an action. If you don’t feel you can talk to the person who wronged you, write about your forgiveness in a journal or even talk about it with someone else in your life whom you trust and can be supportive.

Forgive yourself.

The act of forgiving includes forgiving yourself. Failings of the past are not a reflection of your worth.

If you are suffering any of the debilitating effects of unforgiveness, it is a great day to relieve yourself and others of the tremendous burden of holding on to hurt.  And if you need a professional to speak with about any of the physical effects you are feeling, find them in HealthLynked.

Insight into Vitiligo: The Truth and Treatment of Leucoderma

Today, June 25th, marks World Vitiligo Day, aimed at raising awareness about the disease.  Vitiligo affects roughly 100 million people worldwide and almost 2 million in the US. It’s not contagious or fatal, but scientists are unsure of what causes it.

What is Vitiligo

Vitiligo is a patchy loss of skin coloring (pigmentation). The average age of onset of vitiligo is in the mid-twenties, but it can appear at any age.  95 percent of people with vitiligo have been diagnosed before reaching age forty. It tends to progress over time, with larger areas of the skin losing pigment. Some people with vitiligo also have patches of pigment loss affecting the hair on their scalp or body.

Myths VS Facts

Myth 1: Vitiligo is an outcome of the wrong combination of foods, for instance, milk consumption shortly after eating fish can bring on the disorder.

Fact: Vitiligo has no apparent link with the diet. It is irrational to deprive patients of healthy foods they enjoy in the hope of declining the possibility of the disease.

Myth 2: Vitiligo is a kind of leprosy and is communicable.

Fact: Though often referred to those who do not understand the disease as “white leprosy”, vitiligo is in no way linked to leprosy. It is not infectious or contagious and, hence, cannot pass on from one person to another.

Myth 3: Vitiligo is connected to serious skin diseases, such as skin cancer and albinism.

Fact: There are clear dissimilarities among each of these syndromes, and not of them are linked to Vitiligo.

Myth 4:  There are no effective treatments for vitiligo.

Fact: Medications like steroids, Ultraviolet A, immunomodulator drugs and the newer narrowband Ultraviolet B are accessible, along with several surgical options.

Types of Vitiligo

Generalized vitiligo, also called non-segmental vitiligo, is the most common form.  It involves loss of pigment (depigmentation) in patches of skin all over the body. Depigmentation typically occurs on the face, neck, and scalp, and around body openings such as the mouth and genitals. Sometimes pigment is lost in mucous membranes, such as the lips. Loss of pigmentation is also frequently seen in areas that tend to experience rubbing, impact, or other trauma, such as the hands, arms, and places where bones are close to the skin surface (bony prominences).

Segmental vitiligo is associated with smaller patches of depigmented skin that appear on one side of the body in a limited area; this occurs in about 10 percent of affected individuals.

What causes Vitiligo?

Vitiligo is generally considered to be an autoimmune disorder. Autoimmune disorders occur when the immune system attacks the body’s own tissues and organs. In people with vitiligo the immune system appears to attack the pigment cells (melanocytes) in the skin. About 15 to 25 percent of people with vitiligo are also affected by at least one other autoimmune disorder, particularly autoimmune thyroid disease, rheumatoid arthritis, type 1 diabetes, psoriasis, pernicious anemia, Addison disease, or systemic lupus erythematosus.

In the absence of other autoimmune conditions, vitiligo does not affect general health or physical functioning. However, concerns about appearance and ethnic identity are significant issues for many affected individuals.

Some researchers think that the melanocytes destroy themselves. Others think that a single event such as sunburn or emotional distress can trigger vitiligo. But these events have not been proven to cause vitiligo.

Role of Genetic Changes

Variations in over 30 genes, occurring in different combinations, have been associated with an increased risk of developing vitiligo. Two of these genes are NLRP1 and PTPN22.

The NLRP1 gene provides instructions for making a protein that is involved in the immune system, helping to regulate the process of inflammation. Inflammation occurs when the immune system sends signaling molecules and white blood cells to a site of injury or disease to fight microbial invaders and facilitate tissue repair. The body then stops (inhibits) the inflammatory response to prevent damage to its own cells and tissues.

The PTPN22 gene provides instructions for making a protein involved in signaling that helps control the activity of immune system cells called T cells. T cells identify foreign substances and defend the body against infection.

The variations in the NLRP1 and PTPN22 genes that are associated with an increased risk of developing vitiligo likely affect the activity of the NLRP1 and PTPN22 proteins, making it more difficult for the body to control inflammation and prevent the immune system from attacking its own tissues.

Studies indicate that variations in a number of other genes also affect the risk of vitiligo. Many of these genes are also involved in immune system function or melanocyte biology, and variations in each likely make only a small contribution to vitiligo risk. Some of the gene changes associated with an increased risk of vitiligo have also been associated with an increased risk of other autoimmune conditions.

It is unclear what specific circumstances trigger the immune system to attack melanocytes in the skin. Research suggests that the immune system of affected individuals may react abnormally to melanocytes that are stressed by factors such as chemicals or ultraviolet radiation. In addition, the melanocytes of people with vitiligo may be more susceptible to stress than those of the general population and therefore may be more likely to be attacked by the immune system. The condition probably results from a combination of genetic and environmental factors, most of which have not been identified.

What are the symptoms of Vitiligo?

White patches on the skin are the main sign of vitiligo. These patches are more common in areas where the skin is exposed to the sun. The patches may be on the hands, feet, arms, face, and lips. Other common areas for white patches are:

  • The armpits and groin (where the leg meets the body)
  • Around the mouth
  • Eyes
  • Nostrils
  • Navel
  • Genitals
  • Rectal areas.

People with vitiligo often have hair that turns gray early. Those with dark skin may notice a loss of color inside their mouths.

Will the white patches spread?

There is no way to tell if vitiligo will spread. For some people, the white patches do not spread. But often the white patches will spread to other areas of the body. For some people, vitiligo spreads slowly, over many years. For other people, spreading occurs quickly. Some people have reported more white patches after physical or emotional stress.

How is vitiligo diagnosed?

A doctor will use family and medical history, physical exam, and tests to diagnose vitiligo. The doctor may ask questions such as:

  • Do you have family members with vitiligo?
  • Do you or family members have any autoimmune diseases?
  • Did you have a rash, sunburn, or other skin problem before the white patches appeared?
  • Did you have some type of stress or physical illness?
  • Did your hair turn gray before age 35?
  • Are you sensitive to the sun?

A physical exam will be completed to rule out other medical problems.

Tests might include:

  • Taking a small sample (biopsy) of the affected skin to be examined
  • Blood tests
  • An eye exam.

How is vitiligo treated?

Treatment may help make the skin look more even. The choice of treatment depends on:

  • The number of white patches
  • How widespread the patches are
  • The treatment the person prefers to use.

Some treatments are not right for everyone. Many treatments can have unwanted side effects. Treatments can take a long time, and sometimes they don’t work.

Current treatment options for vitiligo include medical, surgical, and other treatments. Most are aimed at restoring color to the white patches of skin.

Medical treatments include:
  • Medicines (such as creams) that you put on the skin
  • Medicines that you take by mouth
  • A treatment that uses medicine plus ultraviolet A (UVA) light (PUVA)
  • Removing the color from other areas so they match the white patches.
Surgical treatments include:
  • Skin grafts from a person’s own tissues. The doctor takes skin from one area of a patient’s body and attaches it to another area. This is sometimes used for people with small patches of vitiligo.
  • Tattooing small areas of skin.
Other treatments include:
  • Sunscreens
  • Cosmetics, such as makeup or dye, to cover the white patches
  • Counseling and support.

Complications

Vitiligo does not develop into other diseases, but people with the condition are more likely to experience:

  • painful sunburn
  • hearing loss
  • changes to vision and tear production

Overcoming social challenges

If the skin patches are visible, the social stigma of vitiligo can be difficult to cope with. Embarrassment can lead to problems with self-esteem, and in some cases, anxiety and depression can result.  75% of those with vitiligo report having social anxiety in some from as a result of the changes to their skin.

People with darker skin are more likely to experience difficulties, because the contrast is greater. In some countries, vitiligo is known as “white leprosy.”

Increasing awareness about vitiligo, for example, by talking to friends about it, can help people with the condition to overcome these difficulties. Connecting with others who have vitiligo may also help.

Anyone with this condition who experiences symptoms of anxiety and depression should ask their dermatologist to recommend someone who can help.

Five [PLUS] Senses Working Overtime. Are You Tuned In…?

Today is Celebration of the Senses Day – a time to consider your amazing sensory abilities and how they interrelate. We all learn as children humans have five basic senses: touch, sight, hearing, smell and taste. Science has done a fantastic job describing the organs associated with each, how they send information to the brain to help us understand and perceive the world around us, and has gone even further to uncover how they uniquely cross-talk for heightened awareness.

Touch

Touch is thought to be the first sense humans develop, according to the Stanford Encyclopedia of Philosophy. Touch consists of several distinct sensations communicated to the brain through specialized neurons in the skin. Pressure, temperature, light touch, vibration, pain and other sensations are all part of the touch sense and are all attributed to different receptors in the skin.

Touch isn’t just a sense used to interact with the world; it also seems to be very important to a human’s well-being. For example, touch has been found to convey compassion from one human to another.

Touch can also influence how humans make decisions. Texture can be associated with abstract concepts, and touching something with a texture can influence the decisions a person makes, according to six studies by psychologists at Harvard University and Yale University, published in the June 24, 2010, issue of the journal Science.

“Those tactile sensations are not just changing general orientation or putting people in a good mood,” said Joshua Ackerman, an assistant professor at the Massachusetts Institute of Technology. “They have a specific tie to certain abstract meanings.”

Sight

Sight, or perceiving things through the eyes, is a complex process. First, light reflects off an object to the eye. The transparent outer layer of the eye – the cornea – bends the light that passes through the hole of the pupil. The iris (the colored part of the eye) works like the shutter of a camera, retracting to shut out light or opening wider to let in more light.

The cornea focuses most of the light. Then, it passes through the lens, which continues to focus the light.  The lens of the eye then bends the light and focuses it on the retina, which is full of nerve cells. These cells are shaped like rods and cones and are named for their shapes. Cones translate light into colors, central vision and details. The rods translate light into peripheral vision and motion. Rods also give humans vision when there is limited light available, like at night. The information translated from the light is sent as electrical impulses to the brain through the optic nerve.

People without sight may compensate with enhanced hearing, taste, touch and smell, according to numerous studies. Their memory and language skills may be better than those with sight, as well.

“Even in the case of being profoundly blind, the brain rewires itself in a manner to use the information at its disposal so that it can interact with the environment in a more effective manner.”  That’s according to Dr. Lotfi Merabet, senior author of a 2017 study and the director of the Laboratory for Visual Neuroplasticity at Schepens Eye Research Institute of Massachusetts Eye and Ear.

Hearing

This sense works via the complex labyrinth that is the human ear. Sound is funneled through the external ear and piped into the external auditory canal. Then, sound waves reach the tympanic membrane, or eardrum. This is a thin sheet of connective tissue that vibrates when sound waves strike it.

The vibrations travel to the middle ear. There, auditory ossicles — three tiny bones called the malleus (hammer), incus (anvil) and stapes (stirrup) — vibrate. The stapes bone, in turn, pushes a structure called the oval window in and out, sending vibrations to the organ of Corti.  This spiral organ is the receptor organ for hearing. Tiny hair cells in the organ of Corti translate the vibrations into electrical impulses. The impulses then travel to the brain via sensory nerves.

People retain their sense of balance because the Eustachian tube, or pharyngotympanic tube, in the middle ear equalizes the air pressure there with the air pressure in the atmosphere. The vestibular complex, in the inner ear, is also important for balance, because it contains receptors that regulate a sense of equilibrium. The inner ear is connected to the vestibulocochlear nerve, which carries sound and equilibrium information to the brain.

Smell

Humans may be able to smell over 1 trillion scents, according to researchers. They do this with the olfactory cleft, which is found on the roof of the nasal cavity, next to the “smelling” part of the brain – the olfactory bulb and fossa. Nerve endings in the olfactory cleft transmit scents to the brain, according to the American Rhinologic Society.

Dogs are known as great smellers, but research suggests humans are just as good as man’s best friend. Research published in the May 11, 2017, issue of the journal Science suggests humans can discriminate among 1 trillion different odors; it was once believed humans could discern only about 10,000 different smells.

“The fact is the sense of smell is just as good in humans as in other mammals, like rodents and dogs,” John McGann, a neuroscientist at Rutgers University-New Brunswick in New Jersey and the author of the new review, said in a statement. The Rutgers study backs up a previous study at the Rockefeller University in New York, whose findings were published in the March 2014 issue of the journal Science.

Humans have 400 smelling receptors. While this isn’t as many as animals that are super smellers have, the much more complicated human brain makes the difference.  In fact, poor smelling ability in people may be a symptom of a medical condition or aging. For example, the distorted or decreased ability to smell is a symptom of schizophrenia and depression. Old age can also lessen the ability to smell properly. More than 75 percent of people over the age of 80 years may have major olfactory impairment, according to a 2006 paper published by the National Institutes of Health (NIH).

Taste

The gustatory sense is usually broken down into the perception of four different tastes: salty, sweet, sour and bitter. There is also a fifth taste, defined as umami or savory. There may be many other flavors not yet discovered. Also, spicy is not a taste. It is actually a pain signal, according to the National Library of Medicine (NLM).

The sense of taste aided in human evolution, according to the NLM, because taste helped people test the food they ate. A bitter or sour taste indicated that a plant might be poisonous or rotten. Something salty or sweet, however, often meant the food was rich in nutrients.

Taste is sensed in the taste buds. Adults have 2,000 to 4,000 taste buds. Most of them are on the tongue, but they also line the back of the throat, the epiglottis, the nasal cavity and the esophagus. Sensory cells on the buds form capsules shaped like flower buds or oranges. The tips of these capsules have pores that work like funnels with tiny taste hairs. Proteins on the hairs bind chemicals to the cells for tasting.

It is a myth that the tongue has specific zones for each flavor. The five tastes can be sensed on all parts of the tongue, although the sides are more sensitive than the middle. About half of the sensory cells in taste buds react to several of the five basic tastes. The cells differ in their level of sensitivity. Each has a specific palette of tastes with a fixed ranking, so some cells may be more sensitive to sweet, followed by bitter, sour and salty, while others have their own rankings. The full experience of a flavor is produced only after all of the information from various parts of the tongue is combined.

The other half of the sensory cells are specialized to react to only one taste. It’s their job to transmit information about the intensity — how salty or sweet something tastes.

Other factors help build the perception of taste in the brain. For example, the smell of the food greatly affects how the brain perceives the taste. Smells are sent to the mouth in a process called olfactory referral. This is why someone with a stuffy nose may have trouble tasting food properly. Texture, translated by the sense of touch, also contributes to taste, and recent studies even show color and shape can affect the way we perceive a properly attribute taste to a food.

The sense of space

In addition to the traditional big five, other senses help us translate a myriad of inputs into how we perceive and relate to the physical world.  One deals with how your brain understands where your body is in space. This sense is called proprioception.

Proprioception includes the sense of movement and position of our limbs and muscles. For example, proprioception enables a person to touch their finger to the tip of their nose, even with their eyes closed. It enables a person to climb steps without looking at each one. People with poor proprioception may be clumsy and uncoordinated.

Researchers at the NIH found that people who have particularly poor proprioception through mechanosensation — the ability to sense force, such as feeling when someone presses down on your skin — may have a mutated gene that is passed down from generation to generation. That comes from a September 2016 study in the New England Journal of Medicine. “The patient’s version of [the gene] PIEZO2 may not work, so their neurons cannot detect touch or limb movements,” said Alexander Chesler, a principal investigator at the National Center for Complementary and Integrative Health and the lead author of the study.

Additional senses & variations

There are more-subtle senses that most people never really perceive. For example, there are neuron sensors that sense movement to control balance and the tilt of the head. Specific kinesthetic receptors exist for detecting stretching in muscles and tendons, helping people to keep track of their limbs. Other receptors detect levels of oxygen in certain arteries of the bloodstream.

While our five  basic sense seem to operate independently, as distinct modes of perceiving the world, in reality, they collaborate closely to enable the mind to better understand our surroundings. We can become keenly aware of this collaboration under special conditions.

In some cases, a sense may covertly influence another we think is dominant. When visual information clashes with that from sound, sensory crosstalk can cause what we see to alter what we hear. When one sense drops out, another can pick up the slack.  For instance, people who are blind can train their hearing to play double duty. Those who are both blind and deaf can train touch to step in—even to help them interpret speech.

Our senses must also regularly meet and greet in the brain to provide accurate impressions of the world. Our ability to perceive the emotions of others relies on combinations of cues from sounds, sights and even smells.  Perceptual systems, particularly smell, connect with memory and emotion centers to enable sensory cues to trigger feelings and recollections, and are incorporated within them.

The crosstalking of the senses provides some of the most magnificent material for interesting science, illusions, inventions and just plain art.  Here are a few of the best examples of the complex interactions – and extraordinary feats – of our cross-wired senses.

Calling to See

Bats and dolphins, among other animals, emit sounds into their surroundings —not to communicate with other bats and whales — but to “see” what is around them.  They read echoes of the sound waves, which bounce off objects, to identify and locate objects.

This sensory system is called echolocation. Although most of us can only imagine the pictures that form from sound, some sightless people have managed to master a form of echolocation. By uttering sounds and clicks, these individuals can use their ears to navigate. Some, such as Daniel Kish, have even taught others to use this form of human sonar. Kish once described human echolocation as “something like seeing the world in dim flashes of light.”

Fingers Do the Hearing 

People who are both deaf and blind are incredibly good at using other senses, such as touch, to navigate and understand the world. Some use the Tadoma Speechreading Method to perceive speech by touching the lips of another person as they talk. First taught in the 1920s, lip-reading by touch was a popular form of communication among the deafblind. Helen Keller was one of its early adopters.

If taught early in development, the Tadoma Method can help a deaf-blind child learn to speak as well as to understand others. Those who lose their sight and hearing later in life can use it to read lips.

But because the method is extremely difficult and time consuming to learn, by the 1950s it began to lose ground to American Sign Language as the dominant teaching method. Today, only about 50 people in the world still use of the Tadoma Method.

Still, In ASL, the deaf-blind place their hands over another signer’s hands and follow the motions with their fingers—which is easier because the movements are far less subtle.

Beep Baseball

Blind baseball seems almost impossible to even imagine, but since 1975, when a few blind Minnesotans invented “beep baseball”, those who lack sight have taken part in America’s favorite pastime. Thanks to a one-pound beeping oversized softball and some tweaks to the game, players can hit a home run without ever seeing the ball. They use the sound the ball emits to orient themselves, make contact using a bat and to field.  Special bases make it possible to round the diamond. They might be particularly well-suited to this form of the game, as previous research suggests that blind individuals can more easily localize sounds than sighted people can.

Then there is synesthesia

For a few individuals with a condition called synesthesia, the senses collide dramatically and uniquely to form a kaleidoscope world in which chicken tastes like stars, a symphony smells of fresh baked bread or words are bathed in red, green or purple.

People with synesthesia have a particularly curious cross wiring of the senses in which activating one sense spontaneously triggers another. They see colors when they hear noises, associate particular personalities with days of the week, or hear sounds when they see moving dots.

Synesthesia is thought to be genetic, and recent research even suggests it may confer an evolutionary advantage.  Most synesthetes don’t notice anything strange about the way they perceive their environments until it is brought to their attention.

Given that, at any moment in time, we are bombarded by such a diverse combination of sensory experiences, our appreciation of the individual senses can become somewhat muddled. Our taste experience is affected by the smell, texture and temperature of our food. Similarly, our hearing is said to decrease after overeating, and our sight is affected by noises around us. Sight can also be hampered after eating fatty foods.

Here’s another interesting snippet – if a sad, depressed person tells you their world is dull and grey, and flowers have lost their smell, they’re not just speaking metaphorically. Research shows sensory perception can actually be diminished in depressed individuals.  So focussing on a renewed appreciation of your senses can actually help one get out of an emotional rut.

Five senses? More than ten!

The categorization of our five primary senses (sight, smell, hearing, taste and touch) is attributed to Aristotle. While this basic list is still valid, humans have a number of additional ‘sensory abilities’ not covered above. These secondary senses include:

  • Sense of balance and acceleration– the ability to sense body movement, direction and acceleration, and to maintain balance and equilibrium.
  • Temperature sense– the ability to sense heat and the absence of heat (cold).
  • Sense of Pain– the sense of pain was previously believed to be an overloading of pressure receptors, but it has since been identified as a distinct phenomenon that intertwines with the other senses, including touch.
  • Sense of Time– the ability to perceive the passage of time, both short passages as well as longer time cycles.

We are gifted with a complex system of basic and intertwined senses designed to help us take it all in….If any of these seem a little “off” for you, consider seeing a physician who can help you with a tune up.

14 Injections of Fact and Folklore Surrounding the first “Killed” Vaccine

Just 60 years ago, polio was one of the most feared killers in the U.S.

Every year, as the warmer months approached, panic over polio intensified. Late summer was dubbed “polio season.” Public swimming pools were shut down. Movie theaters urged patrons not to sit too close together to avoid spreading the disease. Insurance companies started selling polio insurance for newborns.

The fear was well grounded. By the 1950s, polio had become one of the most serious communicable diseases among children in the United States. In 1952 alone, nearly 60,000 children were infected with the virus; thousands were paralyzed, and more than 3,000 died. Hospitals set up special units with iron lung machines to keep polio victims alive.

Then in 1955, the U.S. began widespread vaccinations. By 1979, the virus had been completely eliminated across the country. Now polio is on the verge of being eliminated from the world. The virus remains endemic in only two parts of the globe: northern Nigeria and the border between Afghanistan and Pakistan.

On this day, June 23rd, 1995, the creator of the first ever “killed” vaccine, which started the US down the path of eliminating the disease, died. Dr. Jonas Salk was 80 years old. Here are a few facts about the medical genius and the disease he and his colleagues worked to eradicate.

Although polio was the most feared disease of the 20th century, it was hardly the top killer.
The first major polio epidemic in the United States hit Vermont in 1894 with 132 cases. A larger outbreak struck New York City in 1916, with more than 27,000 cases and 6,000 deaths. As the number of polio cases grew, the paralytic disease changed the way Americans looked at public health and disability.

Polio, while definitely on a meteoric rise in the 1950’s, was not the rampant killer it has been portrayed to be. During the 50s and 60s, 10 times as many children died in accidents and three times as many succumbed to cancer. Polio inspired such fear because it struck without warning, and researchers were unsure of how it spread from person to person. In the years following World War II, polls found the only thing Americans feared more than polio was nuclear war.

Salk was rejected by multiple laboratories after medical school.
After graduating from medical school at New York University and completing his residency training, Salk applied to laboratories to work in medical research. Rather than treat patients as a practicing physician, Salk hoped to work on the influenza vaccine, a research area he began studying in medical school.

Although he was rejected from multiple labs, perhaps due to quotas that discriminated against Jewish people, he didn’t get discouraged. “My attitude was always to keep open, to keep scanning. I think that’s how things work in nature. Many people are close-minded, rigid, and that’s not my inclination,” he revealed in his Academy of Achievement interview.

Franklin D. Roosevelt and Harry Truman proved instrumental in the vaccine’s development.
A year after his nomination as a Democratic vice presidential candidate, rising political star Franklin D. Roosevelt contracted polio while vacationing at his summer home on Campobello Island in 1921. The disease left the legs of the 39-year-old future president permanently paralyzed. In 1938, five years after entering the White House, Roosevelt helped to create the National Foundation for Infantile Paralysis, later renamed the March of Dimes Foundation, which became the primary funding source for Salk’s vaccine trials. Employing “poster children” and enlisting the star power of celebrities from Mickey Rooney to Mickey Mouse, the grassroots organization run by Roosevelt’s former Wall Street law partner Basil O’Connor was raising more than $20 million per year by the late 1940s.

In 1946, President Harry Truman declared polio a threat to the United States and called on Americans to do everything possible to combat it. “The fight against infantile paralysis cannot be a local war,” Truman declared in a speech broadcast from the White House. “It must be nationwide. It must be total war in every city, town and village throughout the land. For only with a united front can we ever hope to win any war.”

Science initially failed
Early attempts to develop a vaccine ran into numerous hurdles. A vaccine tested on 10,000 children by two researchers at New York University provided no immunity and left nine children dead. Other vaccine trials used “volunteers” at mental institutions.

Salk challenged prevailing scientific orthodoxy in his vaccine development.
While most scientists believed that effective vaccines could only be developed with live viruses, Salk developed a “killed-virus” vaccine by growing samples of the virus and then deactivating them by adding formaldehyde so that they could no longer reproduce. By injecting the benign strains into the bloodstream, the vaccine tricked the immune system into manufacturing protective antibodies without the need to introduce a weakened form of the virus into healthy patients.

Many researchers, such as Polish-born virologist Albert Sabin, who was developing an oral “live-virus” polio vaccine, called Salk’s approach dangerous. Sabin even belittled Salk as “a mere kitchen chemist.” The hard-charging O’Connor, however, had grown impatient at the time-consuming process of developing a live-virus vaccine and put the resources of the March of Dimes behind Salk.

Since Sabin and Cincinnati Children’s Hospital couldn’t gain political support in the U.S. for what he viewed as his superior vaccine, he moved testing to the Soviet Union instead.

Salk tested the vaccine on himself and his family.
After successfully inoculating thousands of monkeys, Salk began the risky step of testing the vaccine on humans in 1952. In addition to administering the vaccine to children at two Pittsburgh-area institutions, Salk injected himself, his wife and his three sons in his kitchen after boiling the needles and syringes on his stovetop. Salk announced the success of the initial human tests to a national radio audience on March 26, 1953.

The clinical trial was the biggest public health experiment in American history.
On April 26, 1954, six-year-old Randy Kerr was injected with the Salk vaccine at the Franklin Sherman Elementary School in McLean, Virginia. By the end of June, an unprecedented 1.8 million people, including hundreds of thousands of schoolchildren, joined him in becoming “polio pioneers.” For the first time, researchers used the double-blind method, now standard, in which neither the patient nor person administering the inoculation knew if it was a vaccine or placebo. Although no one was certain that the vaccine was perfectly safe—in fact, Sabin argued it would cause more cases of polio than it would prevent—there was no shortage of volunteers.

Salk did not patent his vaccine.
On April 12, 1955, the day the Salk vaccine was declared “safe, effective and potent,” legendary CBS newsman Edward R. Morrow interviewed its creator and asked who owned the patent. “Well, the people, I would say,” said Salk in light of the millions of charitable donations raised by the March of Dimes that funded the vaccine’s research and field testing. “There is no patent. Could you patent the sun?” Lawyers for the foundation had investigated the possibility of patenting the vaccine but did not pursue it, in part because of Salk’s reluctance.

Although a tainted batch of the Salk vaccine killed 11 people, Americans continued vaccinating their children.
Just weeks after the Salk vaccine had been declared safe, more than 200 polio cases were traced to lots contaminated with virulent live polio strains manufactured by the Cutter Laboratories in Berkeley, California. Most taken ill became severely paralyzed. Eleven died. In the haste to rush the vaccine to the public, the federal government had not provided proper supervision of the major drug companies contracted by the March of Dimes to produce 9 million doses of vaccine for 1955. Although the United States surgeon general ordered all inoculations temporarily halted, Americans continued to vaccinate themselves and their children. Outside of the “Cutter Incident,” not a single case of polio attributed to the Salk vaccine was ever contracted in the United States.

A rival vaccine supplanted Salk’s in the 1960s.
Once Sabin’s oral vaccine finally became available in 1962, it quickly supplanted Salk’s injected vaccine because it was cheaper to produce and easier to administer. Ultimately, both vaccines produced by the bitter rivals nearly eradicated the disease from the planet. According to the World Health Organization (WHO), there were only 416 reported cases of polio worldwide in 2013, mostly confined to a handful of Asian and African countries. Since Sabin’s live-virus vaccine, which is responsible for about a dozen cases of polio each year, is seen as the final obstacle to eliminating the disease in most of the world, the WHO has urged polio-free countries to return to Salk’s killed-virus vaccine.

Salk was the stepfather of Pablo Picasso’s Children
In 1970, Salk married Françoise Gilot, a French artist who had two children, Claude and Paloma, with Pablo Picasso. In an interview in 1980, Paloma remembered the fear people had of polio, and that as a child, she didn’t visit her father’s house in the South of France due to a polio outbreak. She also revealed that she got along well with her stepfather: “He’s very cute. He’s a wonderful person,” she said. After his death in 1995, Gilot continued her late husband’s legacy by working at the Salk Institute for Biological Studies.

Salk worked on cures for cancer and AIDS
After Salk developed the polio vaccine, he tried to develop vaccines for cancer, AIDS, and multiple sclerosis. Although he wasn’t ultimately successful, he did patent Remune, a vaccine for AIDS to delay the progression of HIV into AIDS. In 2001, six years after Salk died, Pfizer stopped funding clinical trials for Remune due to a lack of evidence that it worked.

Salk was much maligned by the medical community
At the University of Pittsburgh, Salk launched what was then the largest human trial in history and introduced new scientific rigor now used as the gold standard in development of new treatments and tests for pathology. When it was announced that his vaccine worked, Salk was hailed as a humanitarian hero. By 1957, new polio cases had fallen below 6,000.

While heads of state around the globe rushed to celebrate him, many in the medical community derided his efforts. According to Dr. Charlene Jacobs in a interview with the Oxford Press, this was for many reasons:

  1. He preferred the “killed” vaccine, which most in medicine feared would be too weak.
  2. He worked in secret and with a small team.
  3. They claimed he grabbed the limelight and failed to share credit with others.
  4. It appeared he pandered to the press, crossing an imaginary line medicine had set up between science and the media.

Salk won few awards for what is still considered one of the greatest medical breakthroughs
While nominated several times, he did not win the Nobel Peace prize, and he was blackballed from the Academy of Sciences. He won a great deal of social celebrity, for sure, but his insistence on using intuition as much as rigor left many wondering what he really was doing. His dismissal in actual scientific communities is attributed to envy by many who review the history of the time.

Over the years, polio was found to be a highly contagious disease that spread, not in movie theaters or swimming pools, but from contact with water or food contaminated from the stool of an infected person. Along with the vaccine, much was done to improve hygiene in the Americas, The U.S. recorded its last case of polio in 1979, among isolated Amish communities in several states. Then the effort to eradicate polio globally began in earnest. The Western Hemisphere reported its last case, in Peru, in 1991.

Both Salk’s and Sabin’s vaccines are still used today. Although Jonas Salk is credited with ending the scourge of polio because his killed-virus vaccine was first to market, Albert Sabin’s sweet-tasting and inexpensive oral vaccine continues to prevent the spread of poliomyelitis in remote corners of the world. While the later version, which requires just two drops in a child’s mouth, proved much easier to use in mass immunization campaigns, today, it is being marked as the final barrier to truly eliminating polio – it does occasionally infect patients. The complete return to Salk’s vaccine has been promoted by the World Health Organization (WHO) since 2000.
