British Medical JournalThe British Medical Journal has released seven medical myths that they have debunked.

  1. Reading in dim light does not weaken your eyes and leads to glasses. You may have some limited eye blinking and blurriness but nothing should be permanent.
  2. You don’t need to drink 8 glasses of water each day. The American Journal of Psychology said there is no evidence to support this theory.
  3. Shaving does not makes hair grow back faster or coarser. Stubble may feel coarser but it isn’t.
  4. Eating turkey does not make you sleepy. Turkey contains no more trytophan (the amino acid involved in sleep) than beef or chicken.
  5. We use more than just 10% of our brains. The myth originally came about in 1907 but with the invention of the CAT scan and MRI, we can see that we use all of our brain.
  6. Hair and fingernails do not grow after death. The skin does dry out and retract which may give the appearance of longer hair or nails.
  7. Mobile phones do not interfere with medical equipment. Modern mobile phones are safe in hospitals. Although users of mobile phones can be annoying.
