Hit the snooze button—Finally an excuse to stay in bed. A new study published in Paediatrics (2013, doi:10.1542/peds.2013-1274) has found evidence to suggest that increased sleep duration leads to lower weight. In this crossover study, researchers studied the effect of experimental changes in children’s sleep duration on self reported food intake, food reinforcement, appetite regulating hormones, and measured weight. Thirty seven children aged 8-11 years (27% classified as overweight or obese) slept their typical amount for one week; were randomised to either increase or decrease their time in bed by 1.5 hours for one week; and completed the alternative schedule in the third week. The participants randomised to sleep more consumed an average of 134 kcal/day less and had lower fasting morning leptin values than the other group (both P<0.05). Measured weights were 0.2 kg lower during the increased sleep condition (P<0.001).
