The calm of nature benefits us all. When we escape from the crowded and grey environment of towns and cities, we experience a noticeable relaxation and lifting of mood as the green of nature fills our vision. Walking through woodland where the light is predominantly filtered through green leaves creates a sense of calm in the emotions and an expansive , increased sense of connection with our surroundings. The feeling of relaxation and the renewed sense of mental perspective during and after a country walk is so common that few of us will stop to think about it when the walk is over, but we will subconsciously feel profound benefits from the experience .
