Less sleep could mean increased risk for diabetes
Findings from a study reported online in the Journal of Clinical Endocrinology & Metabolism found that deprivation of sleep may actually increase risk for diabetes. According to Plamen Penev, MD, PhD, of the University of Chicago, and colleagues, healthy volunteers, after just two weeks of shortened sleep, became insolent resistance and developed impaired glucose tolerance. When the participants were restricted to 5.5 hours of sleep each night for two weeks they developed a mean of two-hour glucose tolerance test values of 144 mg/dL compared with a mean of 132 mg/dL when they were allowed to sleep for 8.5 hours per night. “These findings suggest that combining the adverse metabolic effects of Westernized lifestyles with chronically reduced sleep duration may increase the long-term risk of developing impaired glucose tolerance and type 2 diabetes,” Dr. Penev and colleagues wrote.
