A study in the Oct. 1 issue of SLEEP suggests that children and teens who keep an “early to bed and early to rise” schedule may be slimmer and more physically active than their night-owl peers. A WebMD article noted that previous studies of sleep and weight may have “missed the mark” by focusing on sleep duration while ignoring sleep schedules.  An article in the Herald Sun reports that the results seem to contradict the idea that a later sleep pattern is healthy for teens.
