We always here hear, even from medical professionals, that, reading in dim light damage your eyes; you need eight glasses of water a day to stay healthy and shaving your legs make the hair grow back faster. A group of researchers delved on scientific bases to prove these common beliefs but it turned out there were none.
Here are the seven common “medical myths”:
- 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.
