WTF Fun Fact 12743 – Laughter is the Best Medicine

We’ve always had lots of anecdotal evidence that “laughter is the best medicine” and studies have shown correlations between laughter and happiness and laughter and better life satisfaction. But in 2005, the first study showed some of the physiological effects laughter has on the body’s cardiovascular system.

So when you say “laughter is the best medicine” to someone and they roll their eyes, you can now hit them with some facts (unless you’re at a funeral or something, then wait a few weeks, please).

The first study

The results of the study were first presented at the Scientific Session of the American College of Cardiology, on March 7, 2005 by researchers from the University of Maryland. It kicked off a whole slew of studies backing up the evidence and providing yet more clues that you can laugh your way into old age.

But first, let’s see how this works. The first study used movies to look at the immediate effects of laughter on subjects’ endothelium – the tissue that forms the inner lining of blood vessels and that dilates or expands during blood flow. (And if it’s been a while since you’ve had a biology class, the better blood flows around your body – and to your heart – the more oxygen and other vital molecules get where they need to be.)

The approach

There were two groups of subjects – one watched a movie clip known to cause mental distress (for example, scenes from Saving Private Ryan – a great film, but not exactly a “cinematic joy ride,” aka it’s sad). The other group watched scenes from funny movies (one example was King Pin, which we have never seen, but we’ll trust that the researchers found a good clip).

Ok, so the goal was really just to make one group laugh and the other get kind of mired in sadness and then measure their blood flow. And you can probably see where this is going.

The results

The distressed group’s blood vessels showed an unhealthy physiological response of the blood vessels called vasoconstriction (a narrowing of the vessels that impedes blood flow). That had been suggested by many other studies before – when we’re stressed, our blood vessels constrict. Not good.

On the other hand, those who laughed showed great blood flow. That’s good. But it’s not just good in the moment, it’s good in the long term because the endothelium helps tone our blood vessels, adjust coagulation rates, and secretes chemicals that help heal wounds and respond to infections.

The researcher’s commentary

In an interview about the study, the lead investigator Michael Miller, M.D., director of preventive cardiology at the University of Maryland Medical Center said: “The endothelium is the first line in the development of atherosclerosis or hardening of the arteries, so, given the results of our study, it is conceivable that laughing may be important to maintain a healthy endothelium, and reduce the risk of cardiovascular disease. At the very least, laughter offsets the impact of mental stress, which is harmful to the endothelium.”

The impact of laughter was so strong that they compared it to the benefits one may get from exercise (thought warned against trying to replace exercise with laughter).

“The magnitude of change we saw in the endothelium is similar to the benefit we might see with aerobic activity, but without the aches, pains and muscle tension associated with exercise,” Miller said. “We don’t recommend that you laugh and not exercise, but we do recommend that you try to laugh on a regular basis. Thirty minutes of exercise three times a week, and 15 minutes of laughter on a daily basis is probably good for the vascular system.”

Further evidence

Since 2005, there have been many studies that show laughter is good for health, including:

  • A study of older Japanese people which found that those who laughed more had fewer heart attacks and stroked.
  • A 2020 study showing that overall mortality, as well as cardiovascular disease, were significantly higher among subjects with a low frequency of laughter.
  • A review essay noting that “many kinds of studies, using different methods, conclude that happiness has a positive causal effect on longevity and physiological health.”

So, ask your doctor today about what a funny movie or a night out with fun friends can do for you. And if they look at you funny, just tell them you read that laughter is the best medicine on the internet. They love hearing that. – WTF fun facts

WTF Fun Fact 12742 – Your Corneas Need to “Breathe”

A lack of oxygen to the cornea can be a very dangerous thing. But we often don’t think about it, and many of us don’t understand why this is the case.

Our bodies need oxygen to function and we get it from our blood. Of course, the most outer layers of our skin and our eyes get some oxygen from the air around us, but there’s one one site on the body where ALL oxygen comes from outside – our corneas.

That’s because the corneas don’t have blood vessels, so there’s no way to get oxygenated blood to reach them.

Obviously, we don’t want blood vessels in that part of our eye anyway, since it needs to be transparent so we can see.

The very outer surface of the center of our eye is the cornea, and it’s in direct contact with the air. It contains cells that require oxygen to live and keep our eyes functioning properly, which is absorbed directly from the air.

This fact is most relevant to those who wear contact lenses, which block most oxygen to the cornea. This is why we’re told to give our eyes “a break” for a few hours each night and switch to eyeglasses. But not everyone does, and the results can be tragic and irreversible.

If our corneas are severely deprived of oxygen, we may experience watery eyes, burning, swelling, and blurred vision. But some vision loss can be permanent.

Without oxygen to your eye, your cornea may start to accumulate lactic acid and pull in more water, causing edema. Oxygen deprivation may result in the development of corneal hypoxia or corneal cysts, which can compromise our vision.

There is an anterior chamber in the eye that can use diffused oxygen and transport it to the cornea from behind, but in most cases, the best ways to keep your eyes safe is to make sure you don’t have them covered with contacts whenever you’re awake.

WTF Fun Fact 12741 – The Force of Teeth Grinding in Humans

Have you ever woken up feeling like someone punched you in the jaw? Or how about with unexplained headaches or even a loose tooth? You might be grinding your teeth.

Well, first, make sure your partner isn’t exhibiting some REM behavior disorder that makes them flail wildly in their sleep. If not, you might want to ask your dentist about bruxism because it can wreak havoc on more than just your teeth.

Bruxism

We all clench our teeth sometimes (like when we’re tense, for example, and it can even be subconscious). While this doesn’t typically do much harm, habitual teeth grinding can affect your jaw and all the muscles around it, leading to neck and head pain and dental issues.

Bruxism, as the teeth grinding condition is called, can also lead to facial changes (it can even change your facial profile) as you lose, chip, or wear down teeth. It can even cause your cheekbones to drop, making your face look droopy and prematurely aged.

Why we grind

According to The Cleveland Clinic, “Men and women get bruxism at roughly the same rate. If you have a family history of teeth grinding, you may face a higher risk. Other risk factors include:

  • Personality type, as people who are very driven may be more prone to teeth grinding.
  • Stress.
  • Cigarette smoking and caffeine use.
  • Certain anti-anxiety medications.”

As you might imagine, bruxism also affects getting a good night’s sleep. So if nothing else, it’s useful to solve the problem so sleep issues don’t cause other problems in your life.

Young children can have bruxism too, and the way they grind teeth it can be caused by anything from allergies to genetics. Often, they outgrow it as their jaws change.

Treatment usually consists of a nightguard, but if you habitually grind your teeth while awake, you may need to train yourself to stop and notice the habit and practice some stress relief techniques.

Two hundred and fifty pounds is a lot of force for a human jaw (most of the time, our molars have about 70 pounds of force, and a strong jaw tops out at about 160 if you’re really trying).

According to the New York Times, “By way of comparison, a well-publicized 1996 study of the tyrannosaurus, done at Stanford, estimated its bite strength ranged from 1,440 to 3,011 pounds, noting that this was fairly close to the power of an alligator’s jaws.”

Now just imagine being a T-rex with bruxism! Ouch. – WTF fun facts

WTF Fun Facts 12723 – No Such Thing As A “Safe Tan”

It’s been decades since we’ve known that tanning beds cause cancer and yet some folks just can’t get enough. It doesn’t help that the tanning industry continues to tout the benefits despite copious scientific evidence that they’re unsafe at best (and, at worst, deadly).

Of course, sun exposure is damaging too, but some of us can’t avoid that – you actually have to walk in and pay for skin damage at a tanning salon dispute there being no physiological benefit (for example, there’s no such thing as a “healthy base tan”).

In addition, a study published in JAMA Internal Medicine estimated that more than 3,200 people are treated for tanning-related injuries in US emergency rooms every year.

It’s hard to hear for many people as “tanning addition” becomes more of a problem, especially among young, white women.

But here are just a few facts from the American Academy of Dermatology Association to provide food for thought:

  • Even one indoor tanning session can increase the risk of developing skin cancer (melanoma by 20%, squamous cell carcinoma by 67%, and basal cell carcinoma by 29%).
  • Nearly 25% of young adults the Academy surveyed were unaware or unsure that tanning beds are not safer than the sun.
  • You can’t get enough vitamin D from tanning beds because the bulbs used emit mostly UVA light; however, your body needs UVB light to make vitamin D.
  • About 20% of 18- to 30-year-old white women who use tanning beds show signs of tanning addiction. When they don’t tan, they even report feeling fidgety or depressed.

And, finally, a Forbes article laid out the issues with indoor tanning as well as some research that shows our desire to tan may actually be influenced by genetics! — WTF fun facts

WTF Fun Fact 12716 – Insurance Pays For Man’s Dishonesty

We’re not even sure where to begin here. But one thing is for sure – if you know you have a sexually transmitted infection, that’s something you tell your partner.

Of course, we’re not sure a Missouri man has learned his lesson after failing to tell his girlfriend he had human papillomavirus (HPV), an STD that can cause cervical and other types of cancers. That’s because it’s his car insurance company, GEICO, who will be paying the $5.2 million in damages for his transgression.

We’ll let Yahoo News explain:

“According to court papers, the woman, identified in court records only as M.O., notified GEICO in February 2021 of her intention to seek monetary damages, alleging she contracted HPV, the human papillomavirus, from an insured member in his automobile. She contended the man caused her to be infected with the STD despite being aware of his condition and the risks of unprotected sex. The insurance company declined the settlement, sending the case to arbitration.”

Of course, GEICO appealed the verdict, but the Missouri Court of Appeals just upheld the settlement and their liability.

“In an opinion issued Tuesday, a three-judge panel found that the judgment entered against GEICO General Insurance Company through earlier arbitration proceedings was valid. The insurance companies sought to undo the action, claiming errors were made in Jackson County Circuit Court and the settlement agreement was not done in line with Missouri law,” writes Yahoo News.

The verdict was first handed down in May 2021, when an arbitrator found that “the man and woman had sex inside his vehicle that ‘directly caused, or directly contributed to cause’ the HPV infection. The man was found liable for not disclosing his infection status and the woman was awarded $5.2 million for damages and injuries to be paid by GEICO.”

The appeals court simply found that GEICO had no legal standing to try to relitigate the case. — WTF fun facts

WTF Fun Fact 12715 – Cherophobia

Anxiety is often irrational, but that doesn’t make it feel less real. However, it becomes a problem when we develop anxiety that interferes with our ability to live life to the fullest.

Take cherophobics for example. Many of us have met people who seem to just refuse to be happy. But those with cherophobia are genuinely concerned that if they do something to make themselves happy, that misery will follow – as if somehow the universe needs to balance out that way.

It’s common to wonder when the other shoe will drop when life is going a bit too well. But those with cherophobia get stressed out at even the thought of having fun.

There’s not a lot of research on the disorder yet, and it has not been added to the DSM to qualify as a mental illness.

But there is one interesting piece of research on cherophobia that gives 4 explanations as to why someone may want to avoid being happy or displaying happiness, and it may depend on culture and upbringing:

  1. A fear that happiness will bring on bad luck
  2. The belief that one doesn’t deserve to be happy while others suffer
  3. The belief that expressing happiness can cause envy in others who will want to prevent your happiness
  4. The idea that pursuing happiness is detrimental to your own soul or to the common good

Frankly, it makes a bit more sense when we see how it may play out in people.

Sadly, cherophobics may not only avoid doing things that make them happy, but they may also pass up opportunities to have meaningful and joyful relationships.

And on that note, we’re going to go call a friend and pour a glass of wine and be thankful for what we have! — WTF fun facts

WTF Fun Fact 12714 – Our Happiest Years

Even people over aged 90 are happier than many of us aged 40 – 59. At least that’s what a UK survey from the Office for National Statistics (ONS) found when they analyzed the well-being data of more than 300,000 adults from 2012 to 2015.

Of course, that doesn’t mean it’s true for everyone – some of us think of our 40s and 50s as a wonderful time when our careers flourish. But overall, that age group reports the lower levels of life satisfaction and the highest levels of anxiety. And while anxiety is higher in women, they tend to report more life satisfaction than men.

According to The Guardian’s report on the survey, “life satisfaction plummeted among respondents aged 35 and over.” This may be due to increased family responsibilities and less time to let loose and have fun.

Researchers stated that “Evidence shows that people are having children later. Therefore, another possible reason for lower scores for the middle-age groups could result from the burden caused by having to care for both parents and children at the same time”

If you are middle-aged and miserable, however, there is a bright spot. Once you hit 60, it’s largely uphill for life satisfaction. People aged 65-79 had the highest levels of personal wellbeing (peaking at ages 70 to 74).

Now, it may be a generational thing as well. Or perhaps with age comes wisdom and the realization that one can choose happiness. We just don’t know for sure.

The important thing to note is that if you feel unduly stressed in your 40s and 50s, you’re pretty much normal – and it does get better. However, ages 50 to 54 may be the worst years. — WTF fun facts

WTF Fun Fact 12682 – France’s Water Cures

Want a prescription to spend 3 weeks at a spa as part of your free healthcare? Become a French citizen! (Ok, that’s no easy task for most of us.)

The New Yorker just published an article that made us long for a doctor’s visit that ended in a “spa cure.” They say:

“Let’s say that you suffer from arthritis, arthritis, bronchitis, bursitis, colitis, diverticulitis, endometriosis, laryngitis, osteoporosis, rhinitis, sinusitis, tendonitis, diabetes, Parkinson’s disease, Raynaud’s disease, multiple sclerosis, angina, asthma, sciatica, kidney stones, sore throat, dizziness, spasms, migraines, high blood pressure, heart palpitations, back pain, earaches, vaginal dryness, menstrual cramps, itching, bloating, swelling, constipation, gout, obesity, gum disease, dry mouth, psoriasis, acne, eczema, frostbite, hives, rosacea, scarring, stretch marks, or varicose veins, or that you are depressed, trying to quit smoking, or simply dealing with a lot of stress. You also, crucially, live in France. You go see the doctor. She writes you a prescription for a thermal cure, indicating to which of the country’s hundred and thirteen accredited thermal spas you will be sent. Then you fill out a simple form and submit it, along with the prescription, to the national healthcare service. Your application is approved—it almost always is—and you’re off to take the waters.“

Ok, first of all, we have a hard enough time getting our medical care approved by our insurance company, we’d love to see their response to a thermal spa receipt for a sore throat. (Seriously, we mean that – we want it on camera.)

Yes, yes, the tax money. Of course. This is not an economic fun fact, because none of that discussion is fun. This is about notions of health and well-being – and you can call them kooky or brilliant, but it’s hard to deny that it’s also fascinating that these treatments – which date all the way back to the ancient world – are still practiced (and paid for) as part of mainstream(ish) medicine. Frankly, it dovetails nicely with much of what we know about the effects of stress and poor mental health on our physical health.

And wait, there’s more:

“The French government introduced “social thermalism” for the masses in 1947, proclaiming that “every man, whatever his social condition, has a right to a thermal cure if the state of his health demands it.” The full cure, consisting of treatments that use mineral water, mud, and steam from naturally occurring hot springs, lasts twenty-one days—six days of treatments with Sundays off, over three consecutive weeks. In 2019, around six hundred thousand French people undertook cures, targeting specific pathologies and subsidized by the state at sixty-five percent. Around three million more visited thermal spas as paying customers.” –  WTF fun fact

WTF Fun Fact 12671 – Appliance-Related Injuries

They don’t make ’em like they used to! While our appliances tend to be lighter as technology advances, they’re also sleeker and more likely to tip over. Unless you have another explanation as to how we end up under our appliances so often.

The U.S. Consumer Product Safety Commission (CPSC) collected ER reports from around the U.S. and found that 22,500 of our annual visits are related to furniture and appliance tip-over injuries.

Of course, when it comes to furniture, we’re thinking some of those are moving-related as well as due to our penchant for buying cheaper products that require us to construct them with a tiny wrench that comes in the box.

And then there are the obvious injuries that happen when our furniture is not secure and children are around. (How often do you use those little wall secure devices that come with bookshelves and console tables?)

The report was released right before the Superbowl, and it’s obvious that flat-screened TVs are a big culprit here, whether they’re on tables or wall-mounted.

According to Newsweek:

“The agency’s report assessed data on what it refers to as “tip-over incidents,” in which a heavy piece of furniture, a television or another appliance falls onto an individual and causes injury or death. The average number of injuries resulting from tip-over incidents reported annually between 2018 and 2020 was 22,500, the report said. About 17,900 of those injuries involved a combination of a piece of furniture and a television, while about 3,700 injuries were attributed to a television that tipped over without the involvement of a piece of furniture. An additional 900 injuries were attributed to appliances.

All of the 22,500 annual injuries required treatment in a hospital emergency department, the CPSC said.”
