How forests help to improve immunity

From the beginning of the human civilization there has been a inseparable relationship between human beings and natural environment. This special attachment with the green surroundings is something unique and cannot be ignored even in the age of rapid urbanization. At present, it is time to analyse whether there is any correlation between natural healing and immunity with green environment. This is not a theoretical issue as it indirectly links up with serious perspectives like conservation of ecology as well.  The Japanese have previously propounded with this idea with their traditional ‘Shinrin-yoku’ where forest bathing is considered to be auspicious for human body including its immune-boosting powers. Forest bathing categorically helps in enhancing natural killer cells which are pivotal to fight diseases like cancer. In case of breathing in green environment of forest, terpenes, which are bioactive substances released by plants, is extremely helpful for the body. These terpenes are not only anti-inflammatory, anti-tumorigenic, and neuroprotective but also being anti-cancer reagents, are extremely beneficial. Interestingly, terpenes also help in reducing stress by lowering cortisol levels.

Phytoncide is another important component which does make camping in forests a brilliant idea. Phytoncide is an essential oil released by trees and plant which boosts immunity and reduces stress to a considerable extent.  Ample exposure to phytoncide promotes complete wellness and that too without any side effect. Let’s not forget its role in curing Attention Deficit Hyperactivity Disorder (ADHD) among kids. It is strange but true that exercising in forests and simply sitting looking at trees reduce blood pressure as well as the stress-related hormones cortisol and adrenaline. According to a study conducted by University of Michigan, walking in forests boost short term memory and helps to combat depression.

Many doctors also conceive that patients recover from surgery faster and better when they have a green view. In other words, green views of the forests can certainly help in fighting out pain, fear, and disruption of normal routine. Very recently, studies in Japan have come up with an interesting proposition. According to them, areas with greater forest coverage have lower mortality rates. Although it is too early to come to a general conclusion, but the research work seems to be extremely positive.

Overall it can be said that impact of green forest and its surrounding on mental health of a person is immense. Thus it won’t be an exaggeration to say that conservation of forests is necessary for the betterment of human civilization.
