Shinrin-yoku (森林浴): A visit to a forest for relaxation and healing

I was lucky to have grown up close to nature for the Japanese, who live in a crowded city.  My parents frequently took me to the mountains, rivers and lakes.  I loved the sound of rivers and sweet smell of earthy air in the forest and mountains.  I feel at home when I’m in the woods because that’s where I can totally relax, get energized, and, above all, feel being part of the universe. 

I often heard of the term, shinrin-yoku, in Japan, so I was surprised to come across this Japanese word in English articles recently.  It’s no surprising that being in nature makes us feel better and relaxed.  However, the recent studies show scientific evidence that being exposed to the forest air has positive physiological effects.  In Japan, as of now, there are 64 accredited areas and trails for shinrin-yoku therapy.

Major effects noted in the studies are:
  • Boosted immune system: increased natural killer (NK) cell activity, the number of NK cells, and levels of anti-cancer proteins
  • Reduced stress: lowered cortisol (stress hormone) and pulse rate
  • Lowered blood pressure
  • Greater parasympathetic nerve activity  

The effects in the studies are often associated with phytoncides, aromatic volatile organic compounds released from trees and plants.  However, forest environments affect us through all of our senses: sight of scenery, smell of wood and flowers, sound of running streams, chirping birds, or the rustle of leaves, feel of grass and trees, and for some people, taste of edible plants.   

Let’s head out for the forests and relax!
