Nature boosts your immune system
Dr. Qing Li, a professor at the Nippon Medical School in Tokyo, believes humans benefit from the anti-viral, anti-fungal and anti-bacterial properties of “phytoncides” which are oils that trees secrete to protect them from rotting and predators. In his 2010 study of 12 Tokyo-dwelling men, 11 of them had an increased amount of “natural killer” cells in blood tests after a three-day trip to the forest. Natural killer cells are a type of white blood cell that act early to wipe out dangerous bacteria and viruses. In another study from Japan, women who spent a few hours in the forest on two consecutive days experienced a boost in white blood cell activity by 50 percent. Feel a cold coming on?
