European countries possess excellent natural resources and lush forests, which have a positive impact on human life and have also encouraged medical and academic professionals to conduct research on how trees can benefit human development.
Recently, a study by the University of Illinois found that looking at trees can reduce psychological stress, and the greater the number of trees, the better the stress-reduction effect. This study confirms the long-held belief that natural landscapes can help alleviate stress.
Similarly, a study published by the University of Glasgow in 2012 showed that for people with depression and anxiety, running through forests has positive health benefits, which are 50% greater than exercising in a gym.
