They also have a positive impact on the immune system by multiplying the number and the activity of the natural killer cells that destroy cancer cells.

Findings of the study suggest that closeness with nature makes one feel more alive and revitalized.

Details of the study
To reach this conclusion, researchers at the University of Rochester looked at 537 student volunteers and carried out five different experiments on them.

In the first experiment, the participants were asked to walk for 15 minutes through indoor hallways or along a tree-lined river path.

In the second experiment, the students were made to view photographic scenes of buildings or landscapes.
