Walking through the woods you enjoy and relax in the beauty of nature. This is why some people choose to live in or near forests, and why other people travel thousands of miles to walk in the rainforests of Costa Rica or Ecuador.
However, scientists in Japan have found that a tradition called Shinri-ioku or “bathing in the forest” is still strong, and why this is so, the reasons are biochemical.
Specifically, scientists have found that staying in the forest enhances natural immunity, which is important for preventing cancer and other chronic diseases.
How is this happening?
When scientists tested people before and after a two-hour walk in the woods, they found that all but one person had 50% or more T-grains. They had lower blood pressure, they felt calm as well as clear in the head.
Forest trees and plants emit “antimicrobial organic compounds of plant derivatives, called phytoncides, to exterminate fungi and bacteria”. Fungi and bacteria can be a problem for our immune system, and it turns out that trees don't like them either.
Trees and other plants have perfected protection, that is, compounds that can kill fungi and bacteria. When you walk through the woods, your breath combines with these components. The effect lasts about 2 months.
