First prescribed by Henry David Thoreau in 1854, eco-therapy is now scientifically proven to improve wellbeing. Forest bathing – basically just being in the presence of trees – is a type of eco-therapy that has proven to lower heart rate, blood pressure, stress hormone production, and increase the immune system and general feelings of wellbeing. This method of relaxation and health practice is gaining popularity, and not a minute too soon.
A forest bath requires a person to just immerse themselves in nature and relax, instead of trying to accomplish anything. For 8 years, Japanese researchers studied the physiological and psychological effects of this method. They found a boost in the immune system of participants, due to an increase in natural killer cells. These cells provide rapid responses to viral-infected cells and respond to tumor formation, and are associated with immune system health and cancer prevention. These positive affects after a few hours in the forest can last for up to a month. These effects can be attributed to phytoncide found in plants and trees in the forests. Trees use this essential oil to protect themselves against bacteria and insects, and humans can use it for an improved immune system.
Nature also had physiological results on participants. They had greater activity in their parasympathetic nerves, which controls the body’s ability to rest and relax. The psychological benefits from forest bathing involved reduced hostility and depressive tendencies among the participants.
Due to the findings of this study, the Japanese government implemented 48 therapy trails throughout local forests. To read the full article, click here.
