Medical Myths Overheard At The Chiropractic Office
In my San Diego based Chiropractic clinic, I hear wives tales regarding health and fitness all the time. The one that I hear most often doesn’t have anything to do with neck pain or back pain - it has to do with knuckle cracking. It seems that almost everyones’ parents have told them “Don’t crack your knuckles, they will get big and full of arthritis when you are older!” Believe it or not, this is not true. Cracking joints that are weight bearing ie, your neck, back, knees and ankles, etc can be harmful if you are not a trained chiropractor, but cracking your knuckles is only irritating to other people.
A study was just released that examined 7 common medical myths that are being circulated today. They are as follows:
Two US researchers took seven common beliefs and searched the archives for evidence to support them.
Despite frequent mentions in the popular press of the need to drink eight glasses of water, they found no scientific basis for the claim.
The complete lack of evidence has been recorded in a study published the American Journal of Psychology, they said.
The other six “myths” are:
Reading in dim light ruins your eyesight.
The majority of eye experts believed it was unlikely to do any permanent damage, but it might make you squint, blink more and have trouble focusing, the researchers said.
Shaving makes hair grow back faster or coarser.
It has no effect on the thickness or rate of hair regrowth, studies say. But stubble lacks the finer taper of unshaven hair, giving the impression of coarseness.
Eating turkey makes you drowsy.
It does contain an amino acid called tryptophan that is involved in sleep and mood control. But turkey has no more of the acid than chicken or minced beef. Eating lots of food and drink at Christmas are probably the real cause of sleepiness.
We use only 10 per cent of our brains.
This myth arose as early as 1907 but imaging shows no area of the brain is silent or completely inactive.
Hair and fingernails continue to grow after death.
This idea may stem from ghoulish novels. The researchers said the skin dries out and retracts after death, giving the appearance of longer hair or nails.
Mobile phones are dangerous in hospitals.
Despite widespread concerns, studies have found minimal interference with medical equipment.
The research was conducted by Aaron Carroll, an assistant professor of pediatrics at the Regenstrief Institute, Indianapolis, and Rachel Vreeman, fellow in children’s health services research at Indiana University School of Medicine.
