After reading our list of 10 Health Myths that even Doctors believe are true, you’ll understand even MDs don’t know everything.

But it’s not just Doctors who’ve fallen for these outdated health myths. Many so-called “Health Experts,” and supposed nutritionists have also been suckered as well.

Just make sure you don’t fall for these whoppers also.

The 10 Health Myths Even Doctors Believe

#1 Drink at least eight glasses of water a day

Despite the seemingly ubiquitous admonition to “drink at least eight 8-oz glasses of water a day”.

Accompanied by, of course, the obligatory warning that beverages containing caffeine and alcohol do not count. 

Rather than questioning this supposed sage advice. Most people just shrug and accept it as gospel.

Unfortunately, when Physiological experts sought to find the origin of this ‘8 Glasses Of Water A Day” advice (called “8 x 8” for short) and to examine the scientific evidence if any, that might support it. 

Researchers could find no evidence that supports the “8 x 8” claim.

The best advice for staying hydrated is to drink frequently throughout the day, even if you’re not thirsty. But please, forget trying to force yourself to drink 8 glasses a day!

#2 Plenty Of Bed Rest For Back Pain

Years ago, while I was playing basketball, I went one way and my back decided to go the other.

As a result, three ruptured disks, L1, L2, and L4.

When the hospital released me the physician was adamant about bed rest.

10 years later my back still isn’t where it was before my accident. But the one thing I have learned over the years was the more bed rest I got, the worse my back became.

Today, Doctors still hand out this advice—but it’s been decades since bed rest was prescribed for back pain.

The American College of Physicians now recommends that doctors and patients should treat low back pain with non-drug therapies like heat, massage, tai chi, yoga, acupuncture, or spinal manipulation (chiropractic), and over-the-counter pain meds. 

They also want patients to try and stay active, something that I’ve learned is the best thing you could do for an aching back.

#3 Shaved Hair Grows Back Faster, Thicker, and Darker

Shaving your hair doesn’t change its thickness, color, or rate of growth, according to the Mayo Clinic.

But you don’t need the Mayo Clinic to confirm this idiocy. All you need is a bit of logic.

If this myth was true imagine what would happen to a man who has been shaving his face for 50-years?

He would need a chain saw to shave. Besides the fact it would probably be regrown by the time he finished shaving.

Plus, if this myth was even remotely true. Then wouldn’t men start shaving their heads the moment they notice their hair was starting to thin or go gray?

#4 We Use Only 10 percent of Our Brains

Not only has everyone’s heard this one, but with movies such as Limitless, Hollywood has raked in millions off of this silliness.

Bottom line, we don’t use 10% or 25% of our brains…We use 100% of our brains, says Scientific American.

Hell, we even use our brains when we’re sleeping. 

#5 Reading in dim light will damage your eyesight

Dim lighting has no effect on eyesight, according to Harvard Medical School.

But, it will tire your eyes more quickly.

The best way to position a reading light is directly over the page; just make sure you position it to avoid glare.

#6 Hair and fingernails continue to grow after we die

Ah, you see this one a lot in horror films. When the supposed dead spring back to life, you know what you’re getting them for Christmas.

A gift certificate to Supercuts and another for a nice manicure, and if you’re feeling extra ‘Merry’ that year I’m sure a pedicure would make a wonderful stocking stuffer.

While Hollywood has done their best to make dead bodies as creepy as possible, it’s still untrue.

The growth of hair and nails requires a complex hormonal interaction that just isn’t possible after death.

This myth is probably rooted in the fact that after death, the human body dehydrates, and skin shrinks, exposing more of the nails and hair.

So it may appear that your hair and nails have grown, but the fact is your body tissue just decreased.

#7 If you don’t have a maternal history of breast cancer, you’re low risk

This couldn’t be further from the truth.

According to the National Breast Cancer Foundation, only about 10 percent of those diagnosed with breast cancer have a family history of the disease.

And among those, it’s not just mom that matters: Although many doctors were taught to ask about a woman’s mother when calculating breast cancer risk, we now know it’s possible to inherit problematic genes from your father’s or your mother’s DNA.

#8 If you have osteoarthritis of the knee, get surgery

Several landmark studies discovered that people do just as well—or better—when they skip surgery and just do physical therapy.

Arthroscopic knee surgery, a commonly performed orthopedic procedure in the United States, may only be effective for a narrow group of people with chronic knee pain, according to the results of a study published in the New England Journal of Medicine. 

This adds to earlier research suggesting that the procedure may be unnecessary for most people with knee osteoarthritis.

#9 Sex is painful for a woman because she can’t relax

Once doctors have ruled out obvious causes for painful sex like an infection or poor vaginal lubrication, they may offer this explanation.

But there are many reasons for painful sex, such as vestibulodynia—the most common cause of sexual pain in women under 50. This chronic vulvar pain doesn’t have a clear cause—or cure.

Any kind of touch or pressure can trigger discomfort, whether it’s sex, toilet paper, or tampons, according to Harvard Medical School.

Topical treatments and avoiding tight-fitting clothing can help; the condition can clear up on its own, though it can take months or even years.

But do Doctors really blame a woman when they can’t find an answer?

I can tell you that they absolutely, 100%, without a doubt, do.

After my wife had our first child, suddenly making love became painful. 

After suffering through a range of tests, not to mention the embarrassment of describing what ailed her.

The Doctor finally concluded that she just needed to relax.

In fact, multiple Doctors all concluded that my wife’s pain was emotional, not physical.

My Lord, one Doctor even went so far as to suggest we drop the little one off at granny’s and go out drinking.

#10 Strokes Only Happen When You’re Old

Stroke is the fifth-leading cause of death nationwide. But it’s common to mistake that it only happens to the elderly.

A 2016 study of New Jersey hospitalizations published in the Journal of the American Heart Association reveals that the incidence of stroke has more than doubled in people between the ages 35 to 39 over the last decade.

Another study in 2017, in JAMA Neurology found the highest increase was among women between 35 and 44—the group suffered a 42 percent jump. 

So the answer is an unequivocal NO!
