Dr. Gray links the astronomical rise in childhood depression and anxiety disorders, which are five to eight times more common than they were in the 1950s, to the decline in free play among young children. “Young people today are less likely to have a sense of control over their own lives and more likely to feel they are the victims of circumstances, which is predictive of anxiety and depression,” he said.
There are also physical consequences to restricting children’s outdoor play because there are no adults available to supervise it. Children today spend many more hours indoors than in years past, which in part accounts for the rise in childhood obesity and Type 2 diabetes. Many elementary schools have even canceled recess, believing it is time better spent cramming children’s heads with facts and figures.
