A study of healthy adults is one of the first to show a correlation of sleep amount and time with the body’s metabolism. Researchers pointed out that going to bed too early may prove as problematic as going too late. Postulated is that a¬†misalignment in everyday life may impact risk for obesity with sleep as a driver of the body’s metabolic activity. All agree that more study is needed. At this posting there is no bedtime practice to suggest.

Subjects kept food diaries, blood draws were taken to determine melatonin levels. FYI-people produce melatonin starting 2 hours before bedtime. Furthermore each subject was weighed each morning, their height was measured to determine BMI and body fat was measured using dual emission x-ray absorptiometry.

Other study results also suggest sleep timing is linked to obesity, diabetes, and the risk for metabolic syndrome.
