A has about 500 calories.

The study compared data from other research projects on obesity and sleep duration. The findings are more pronounced for children and .

"While it might be natural to think that sleeping less (or being awake more) means you use more calories and should therefore lose weight, studies have shown the opposite to be the case," said the statement.

"Interventions as simple as extending the nightly sleep duration in these younger, habitual short sleepers should be explored to prevent obesity."

Six hours are considered a period in adults and seven to eight hours a healthier one.
