7 medical prejudices without scientific basis

7 medical prejudices without scientific basis
Back in 2008, American scientists published 7 medical prejudices in the British Medical Journal. Those prejudices are all without almost any scientific basis.

  1. You should drink 8 glasses of water a day – women’s magazines often state that taking 8 glasses of water a day is extremely healthy, although doctors say that no one has proven this claim yet.
  2. Reading in low light is detrimental to vision – most ophthalmologists, however, claim that low light is unlikely to have lasting effects. It can only cause more frequent blinking or difficulty in visual acuity.
  3. Shaving accelerates hair growth – there is no evidence that shaving affects the thickness or density of hair, although short sharp hairs that grow after shaving leave such an impression (unlike long hairs that are thin at the ends).
  4. Taking turkey meat puts you to sleep – this is a misconception without scientific evidence. The fact is that it goes best with potatoes and a light salad. It contains the amino acid tryptophen, which is metabolized into serotonin (a substance that affects sleep and mood). Turkey meat, however, contains the same amount of tryptophen as chicken or beef.
  5. Many claim that people use only 10% of the brain’s capacity – neurologists say that no area of ​​the brain is completely inactive.
  6. Hair and nails grow after death – scientists have a different explanation. The skin dries and pulls off the nails after death. The nails look longer after a while.
  7. Mobile phones are dangerous in hospitals — research says there is minimal interference from mobile phones to medical equipment but this interference is not dangerous to health.
