Blowing on or licking a wound
Parents everywhere are known for spitting on a tissue and using it to clean their children’s faces and sometimes even to clean a wound. Blowing on or introducing saliva to a cut is very dangerous. “Our breath and saliva have tons of bacteria which can contaminate the wound and lead to an infection,” says Dr Kogan. Instead, use fresh water and consult a doctor if needed.
Vitamins
As long as you follow a healthy diet, you’ll get all the vitamins and minerals you need. That’s good because sliding into the habit of trying to make up supposed deficiencies with supplements can quickly lead to trouble, warns Dr Kogan. The danger comes when people ignore the recommended doses and take too much of a particular vitamin. Too much vitamin D, for instance, can cause liver and heart problems, while an overabundance of B6 can lead to nerve toxicity; a vitamin A overdose can even cause death in extreme cases.
