The stress of an unpleasant environment can cause you to feel anxious, or sad, or helpless. This in turn elevates your blood pressure, heart rate, and muscle tension and suppresses your immune system. A pleasing environment reverses that.
Being in nature, or even viewing scenes of nature, reduces anger, fear, and stress and increases pleasant feelings. Exposure to nature not only makes you feel better emotionally, it contributes to your physical wellbeing, reducing blood pressure, heart rate, muscle tension, and the production of stress hormones.

In another interesting area, Andrea Taylor’s research on children with ADHD shows that time spent in nature increases their attention span later.
