Kids who exercise tend to be happier: Did you know
Syracuse (WSYR-TV) -- We all know that exercise is good for us. But did you know that physically active children tend to be in happier moods and show fewer symptoms of depression?
Researchers looked at a group of 258 8-year-old kids. They wore accelerometers on their wrists for at least four days that registered the quality and quantity of their physical activity. Their parents also took swabs of their saliva to measure levels of the hormone cortisol, which is induced by physical or mental stress.
The research showed that children who were not as physically active had higher levels of cortisol when presented with a stressful situation, such as having to solve arithmetic problems or storytelling challenges. The children who were more active had a more positive response.
