“At the very moment the bond is breaking between the young and the natural world, a growing body of research links our mental, physical, and spiritual health directly to our association with nature – in positive ways.” Richard Louv Author of “Last Child in the Woods --Saving Our Children from Nature-Deficit Disorder”
Goal: This training will create Nature Champions among healthcare providers to connect children and families with nature for health benefits
Learning Objectives • Explain the evidence surrounding health and activity levels of children, particularly as they pertain to natural environments. • Explain the benefits of outdoor play on children’s physical and mental health. • Examine the role that natural environments have in improving outdoor physical activity for children. • Prescribe resources available to help your patients access the outdoors for health benefits.
The Challenge… • “Physical inactivity is the major public health issue in this country.” • “If we are going to survive as a nation, if we’re going to thrive as a nation, we really have to change that focus on sickness and illness to one of health, prevention and wellness.” Acting US Surgeon General Rear Admiral Boris Lushniak
Your Role… • “Health care professionals are on the front lines of the battle against obesity and metabolic disease. They are uniquely positioned to prompt change among individuals, families and society as a whole. That’s why we need to ensure that they have the tools to help their patients practice healthy lifestyles.” Donna Shalala, former Secretaryof Health and Human Services and President of the University of Miami
