We all deal with various levels of stress and it can affect our bodies in a number of ways, both mental and physical.
High levels of long-term chronic stress can lead to reduced cognitive function, anxiety disorders and depression. Anxiety disorders are the most common mental illness in the U.S., affecting 40 million adults, or 18 percent of the U.S. population. This number results in a cost of $42 billion per year, which is almost a third of the country’s $148 billion mental health bill. According to the National Center for Health Statistics (NCHS), there has been a 400 percent increase in the number of teens and adults medicated with anti-depressants, which are used to treat anxiety, between 1988-1994 and 2005-2008.
Chronic stress is takes a major toll on our physical health, directly contributing to headache, poor sleep habits and a decreased immunity - people who are stressed out get sick more often. It can lead to high blood pressure and heart disease. Stress exacerbates anything that may already be wrong with us, making us feel worse.
How Nature Helps
Numerous studies have shown that access to trees and green spaces calm us and help to alleviate stress. One such study found that trees and green space are a major predictor of longevity, especially among people living of lower-incomes communities.

Role of the Landscape Architect
Understanding the importance that a place of peace and refuge can have on our day to day lives, landscape architects are able to take some of the edge off our modern existence by designing parks that provide us with quiet places.
Paley Park in New York City is a small and enclosed space, whose use of rushing water blocks out the noise of the city as soon as you walk in. The trees provide shade, and you are immediately cooled.
Lurie Garden in Chicago also makes use of water, offering places to sit for spell and inviting people to soak their feet, all within a lush garden densely planted with flowers.
