Revealed: The seven great "medical myths"
LONDON (Reuters) - Reading in dim light won't damage your eyes, you don't need eight glasses of water a day to stay healthy and shaving your legs won't make the hair grow back faster.
These well-worn theories are among seven "medical myths" exposed in a paper published Friday in the British Medical Journal, which traditionally carries light-hearted features in its Christmas edition. Two U.S. 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 believe it is unlikely to do any permanent damage, but it may 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 percent 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.

Unhappy? Self-Critical? Maybe You’re Just a Perfectionist
Just about any sports movie, airport paperback or motivational tape delivers a few boilerplate rules for success. Believe in yourself. Don’t take no for an answer. Never quit. Don’t accept second best.
Above all, be true to yourself.
It’s hard to argue with those maxims. They seem self-evident — if not written into the Constitution, then at least part of the cultural water supply that irrigates everything from halftime speeches to corporate lectures to SAT coaching classes.
Yet several recent studies stand as a warning against taking the platitudes of achievement too seriously. The new research focuses on a familiar type, perfectionists, who panic or blow a fuse when things don’t turn out just so. The findings not only confirm that such purists are often at risk for mental distress — as Freud, Alfred Adler and countless exasperated parents have long predicted — but also suggest that perfectionism is a valuable lens through which to understand a variety of seemingly unrelated mental difficulties, from depression to compulsive behavior to addiction.
Some researchers divide perfectionists into three types, based on answers to standardized questionnaires: Self-oriented strivers who struggle to live up to their high standards and appear to be at risk of self-critical depression; outwardly focused zealots who expect perfection from others, often ruining relationships; and those desperate to live up to an ideal they’re convinced others expect of them, a risk factor for suicidal thinking and eating disorders.
“It’s natural for people to want to be perfect in a few things, say in their job — being a good editor or surgeon depends on not making mistakes,” said Gordon L. Flett, a psychology professor at York University and an author of many of the studies. “It’s when it generalizes to other areas of life, home life, appearance, hobbies, that you begin to see real problems.”
Unlike people given psychiatric labels, however, perfectionists neither battle stigma nor consider themselves to be somehow dysfunctional. On the contrary, said Alice Provost, an employee assistance counselor at the University of California, Davis, who recently ran group therapy for staff members struggling with perfectionist impulses. “They’re very proud of it,” she said. “And the culture highly values and reinforces their attitudes.”
Consider a recent study by psychologists at Curtin University of Technology in Australia, who found that the level of “all or nothing” thinking predicted how well perfectionists navigated their lives. The researchers had 252 participants fill out questionnaires rating their level of agreement with 16 statements like “I think of myself as either in control or out of control” and “I either get on very well with people or not at all.”
The more strongly participants in the study thought in this either-or fashion, the more likely they were to display the kind of extreme perfectionism that can lead to mental health problems.
In short, these are people who not only swallow many of the maxims for success but take them as absolutes. At some level they know that it’s possible to succeed after falling short (build on your mistakes: another boilerplate rule). The trouble is that falling short still reeks of mediocrity; for them, to say otherwise is to spin the result.
Never accept second best. Always be true to yourself.
The burden of perfectionist expectations is all too familiar to anyone who has struggled to kick a bad habit. Break down just once — have one smoke, one single drink — and at best it’s a “slip.” At worst it’s a relapse, and more often it’s a fall off the wagon: failure. And if you’ve already fallen, well, may as well pour yourself two or three more.
This is why experts have long debated the wisdom of insisting on abstinence as necessary in treating substance abuse. Most rehab clinics are based on this principle: Either you’re clean or you’re not; there’s no safe level of use. This approach has unquestionably worked for millions of addicts, but if the studies of perfectionists are any guide it has undermined the efforts of many others.
Ms. Provost said those in her program at U.C. Davis often displayed symptoms of obsessive-compulsive disorder — another risk for perfectionists. They couldn’t bear a messy desk. They found it nearly impossible to leave a job half-done, to do the next day. Some put in ludicrously long hours redoing tasks, chasing an ideal only they could see.
As an experiment, Ms. Provost had members of the group slack off on purpose, against their every instinct. “This was mostly in the context of work,” she said, “and they seem like small things, because what some of them considered failure was what most people would consider no big deal.”
Leave work on time. Don’t arrive early. Take all the breaks allowed. Leave the desk a mess. Allow yourself a set number of tries to finish a job; then turn in what you have.
“And then ask: Did you get punished? Did the university continue to function? Are you happier?” Ms. Provost said. “They were surprised that yes, everything continued to function, and the things they were so worried about weren’t that crucial.”
The British have a saying that encourages people to show their skills while mocking the universal fear of failure: Do your worst.
If you can’t tolerate your worst, at least once in a while, how true to yourself can you be?
