Nature.

Stress Reduction:

Nature possesses a great power to quiet our minds and soothe our frazzled nerves. It has been demonstrated that exposure to the sights and sounds of nature, such as the soothing rustle of leaves in the breeze or the melodic singing of birds, reduces stress hormone levels and encourages relaxation. There can be a great deal of relief from the daily grind by spending time in green areas like parks, forests, or gardens.
