How to never get ill: Take a nap
History has many accomplished nappers.Leonardo Da Vinci took short naps every few hours; Napoleon Bonaparte dozed on his horse. And very wise they were, too.
Lack of sleep causes the body to produce more of the hormone cortisol, which gives us energy but restricts production of human growth hormone — limiting the body’s ability to repair itself.
This backed up the theory that our bodies use dormant hours to regenerate and fight disease (by producing immune cells called monocytes).
