Research shows that children who play outside regularly have healthier body weight, improved vision, and immune function, reduced stress, better sleep, improved motor skills. There are substantial immediate and long-term health consequences for children who aren't able to play outside or get enough physical activity such as increased obesity and chronic diseases. The research also shows us that kids who play outdoors have increased school readiness because outdoor play contributes to better social skills such as cooperation, increased attention span, improved school attendance, and improved brain development and cognition. Physical activity plays a critical role in supporting health and learning.

Families “are naturally concerned for their child’s safety, particularly when cared for outside of the home. However, children who spend more time in nonparental child care have a reduced risk of (unintentional) injury. This may be because child care centers and family day homes provide more supervision and/or safer play equipment. Nevertheless, injuries in child care settings remain a serious, but preventable, health care issue.”55
