Children who sleep less more likely to be overweight

A Northwestern University study found that getting inadequate sleep increases the risk of being overweight in children. The five-year study, conducted on a nationally representative sample of 2,182 children aged 3-18, suggests that even an extra hour of sleep can reduce a child's chance of being overweight.
