Nature and Mental Health At this essay I make an effort to find the connection between the human mental health and the physical environment, including the animals as part of it. Generally, a positive effect at a person's mental balance seems to happen when one visit a forest or a river. It makes the person to relax and clear the mind. So, what are the factors that make this possible? Does the nature have a "secret" to improve our mood and alleviate us from stress? Lets break down the characteristics of the natural environment. Usually, a forest or a park is located far away from the noise of a city. Thus, stay some hours there, for example for walking, means the absence of noise.Furthermore, trees are the "factories" of oxygen. It makes sense to feel better if you breathe clear oxygen. Finally, the harmony of the colors around you in conjunction with the sound of birds subconsciously work as a therapist of your soul. Taking all this into account, we estimate the importance of the physical environment for the quality of our every day life, since a person with good mental healt can be more efficient at every aspect of the social life.
