Sleeping 90 minutes later a day leads to 0.5 kg weight gain in six weeks, study says
Cutting sleep by about 80 minutes a night can lead to weight gain in six weeks, a study found. Adults who usually slept 7 to 8 hours and delayed bedtime by about 90 minutes slept 78.4 minutes less on average and gained about 0.5 kg over six weeks. Researchers also saw more sedentary time and suggested mild but sustained sleep loss may affect weight, metabolic health and cardiovascular health.
