The XO Directory

A review of evidence by US researchers surrounding seven commonly-hold medical beliefs suggests they are actually "medical myths". Two U.S. researchers searched the archives for evidence to support them, but they found nothing. Some are utterly untrue, while others have no evidential proof, the British Medical Journal reports.

The Seven Medical Myths Are:
1. Drink eight glasses of water daily
2. Reading in dim light ruins your eyesight
3. Shaving makes hair grow back faster or coarser
4. Eating turkey makes you drowsy
5. We use only 10 percent of our brains
6. Hair and fingernails continue to grow after death
7. Mobile phones are dangerous in hospitals
