College students today display disturbing levels of stress, depression, and other psychological conditions. The reasons for this rise in mental health problems are many, from increased reliance on electronic technology, the related prevalence of social isolation, and anxiety regarding societal ills. College and university counselling centers are challenged to address student demand for psychological services, with many counseling directors having to reduce the number of visits for non-crisis patients to cope with the increasing number of clients.
While more serious mental health problems will continue to be addressed through intensive counseling, medications and, in extreme cases, hospitalization, the majority of young people can positively impact their mental well-being by simply spending time outside in nature. A large body of scientific evidence verifies that time spent in natural settings can lower young people's stress levels, anxiety, blood pressure and heart rate, and improve memory and cognitive functions.
College Nature Rx programs encourage students to spend time in nature and to develop greater appreciation for the natural world. We present a step-by-step formula for how such programs can be constructed, sustained, and evaluated, and profile four progressive Nature Rx programs at American colleges. In a final chapter, we argue for the need for such programs to the future health and strength of such institutions.
