Forest bathing boosts the immune system

A series of experiments conducted by Dr Li in Japan found that the natural killer cell activity (an indicator of immune function) increased by up to 50% after 2-3 days walking in a forest. An increase of about 20% was maintained for up to 1 month after the forest immersion. Li continued studying the effects of forest bathing on the physiological and psychological wellbeing of humans over a period of 15 years. He measured heart rate, blood pressure, adrenaline, cortisol, brain activity and NK cells activity, before, during and after time spent in forests and found that forest bathing has a significant positive impact on human health.
