In a group of 900 healthy people, researchers observed sex-specific relationships between sleep duration and glucose metabolism, said study’s senior researcher,Femke Rutter, from the VU Medical Center in Amsterdam, The Netherlands. The study found that men who slept the least and the most were more likely to have an impaired ability to process sugar compared to those who slept an average of about seven hours. The men at either end of the spectrum had higher blood sugar levels than those who got the average amount of sleep.
Women who slept less or more than average, however, were more responsive to the hormone insulin than women who slept the average amount. The study was published in the Journal of Clinical Endocrinology and Metabolism.
