Life today is full of stressors, and this is especially true for college and university students. To improve students’ mental and physical well-being, Don Rakow, an associate professor in the Horticulture Section of the School of Integrative Plant Science at Cornell, recommends a prescription of fresh air. In a book coauthored with Gregory T. Eells, Nature Rx: Improving College-Student Mental Health (Cornell University Press, 2019), Rakow argues that campus programs encouraging students to spend more time outdoors can reduce the stress and anxiety of academic, social, and relationship pressures, particularly for those also dealing with mental health issues, trauma, or substance abuse. In this Chats in the Stacks talk, Rakow will discuss the value of Nature Rx programs and present a step-by-step formula for constructing and sustaining them on college campuses. This book talk is supported by the Mary A. Morrison Public Education Fund for Mann Library.
