Shows how outdoor play and unstructured freedom of movement are vital for children's cognitive development and growth, and offers tons of fun, engaging ways to help ensure that kids grow into healthy, balanced, and resilient adults. Today's kids have adopted sedentary lifestyles filled with television, video games, and computer screens. But more and more, studies show that children need "rough and tumble" outdoor play in order to develop their sensory, motor, and executive functions. Disturbingly, a lack of movement has been shown to lead to a number of health and cognitive difficulties, such as attention deficit/hyperactivity disorder (ADHD), emotion regulation and sensory processing issues, and aggressiveness at school recess break. Nature is the ultimate sensory experience, and psychological and physical health improves for children when they spend time outside on a regular basis.
