Medical Myths

A new report debunks some long-held medical myths:

  • People should drink at least eight glasses of water a day
  • We use only 10% of our brains
  • Hair and fingernails continue to grow after death
  • Shaving hair causes it to grow back faster, darker, or coarser
  • Reading in dim light ruins your eyesight
  • Eating turkey makes people especially drowsy
  • Mobile phones create considerable electromagnetic interference in hospitals.
Authors Rachel Vreeman and Aaron Carroll checked them out and found all of them either false or unproven.
