Dr. Melissa Lem, a Vancouver family physician and longtime advocate of the health benefits of nature, remembers feeling that same quieting effect while spending time outdoors. Despite the challenges, she loved the work and credits easy access to nature as part of what helped her cope. A systematic review from 2018 included 143 studies on the topic from the previous decade, illustrating a recent and rapid growth in the study of nature and health. Nature prescriptions, or “nature pills,” are a growing area of interest for researchers and medical practitioners. “I think it’s important for nature to become routine advice during a health care visit—diet, exercise, sleep, and nature time.” Lem calls these the four central pillars of health, and she’s excited to see the movement growing among physicians.
