“Spending 20 to 30 minutes in nature significantly reduces rates of depression, lowers blood levels of the stress hormone cortisol, blood pressure and heart rate, and stimulates memory and creativity,” said Dr. Claudel Pétrin-Desrosiers, a clinical lecturer at the University of Montreal’s Department of Family Medicine and Emergency Medicine and a family physician at the CLSC de Hochelaga-Maisonneuve. “Contact with nature is one of the only clinical approaches that has no adverse effects.”
In fact, the benefits of nature for physical and mental health are so great that “prescriptions for the great outdoors” are now part of many health care professionals’ arsenals, here at home and abroad. The recommended dose: a minimum of two hours per week spent surrounded by greenery, 20 minutes or more at a time.
“This is an attractive way to promote overall health as we adjust to climate change,” said Pétrin-Desrosiers, one of Quebec’s most prominent and credible figures in the fields of health and environment.
