Go Outside and Enjoy Nature to Improve Your Immune System

Spending time in nature might benefit your immune function.  Stress reduction is one reason, but another is the presence of phytoncides, the airborne chemicals that plants emit to protect themselves from rotting and insects.

One study found that being among plants resulted in lower concentrations of cortisol, lower pulse rate, and lower blood pressure.

According to the New York Times:

“A number of other studies have shown that visiting parks and forests seems to raise levels of white blood cells, including one in 2007 in which men who took two-hour walks in a forest over two days had a 50-percent spike in levels of natural killer cells. And another found an increase in white blood cells that lasted a week in women exposed to phytoncides in forest air.”
