Sustaining the Human Spirit: The Effect of Interior and Outdoor Greening on Urban Inhabitants

Tina Marie (Waliczek) Cade, Texas State University – San Marcos 
Human beings are drawn to nature. With urbanization and technological advances, this need for natural places is often overlooked in both indoor and outdoor settings. However, passive and active interactions with plants and green spaces have positive effects on well-being, including physical, psychological, and spiritual effects. The benefits have been shown for both the general population and special populations of people. These research findings will be introduced, as well as the theoretical basis as to why we need nature in our environments.
