Short Sleep Duration Linked to Increased Abdominal Fat

April 01, 2018 - Admin

The Hitachi Health Study in Japan found that sleep-deprived people had greater body mass index (proportion of weight to height), waist circumference and surface fat than people who slept seven to nine hours per night. They used CT scans to precisely measure abdominal fat and fat around the organs. Age, physical activity, smoking, drinking, or health status did not influence the relationship. Researchers concluded that short sleep duration was linked to total body fat, abdominal fat and surface fat in Japanese men. Many studies linked inadequate sleep to obesity, but scientists aren’t sure why. (International Journal of Obesity, 37: 129-134)
