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. It may even reduce mortality, according to scientists such as public health researchers Stamatakis and Mitchell.
Research done in hospitals, offices, and schools has found that even a simple plant in a room can have a significant impact on stress and anxiety.
In addition, nature helps us cope with pain. Because we are genetically programmed to find trees, plants, water, and other nature elements engrossing, we are absorbed by nature scenes and distracted from our pain and discomfort
Spending time outside is good for the heart, research shows, and since high blood pressure costs the U.S. approximately $48.6 billion per year and affects 1 in 3 Americans, visiting green spaces may be a simple and affordable way to improve heart health. A large June 2016 study found that nearly 10% of people with high blood pressure could get their hypertension under control if they spent just 30 minutes or more in a park each week. “If everyone were to make time for nature, the savings on health care costs could be incredible,” says study author Danielle Shanahan, a research fellow at the University of Queensland in Australia.
