Diabetes Risk Tied to Lack of Sleep
Sleeping for less than six hours or for more than nine hours each night is associated with an increased risk of diabetes and impaired blood sugar (glucose) tolerance, researchers report in this week's issue of the Archives of Internal Medicine.
Sleeping for at least seven hours a night, Dr. Daniel Gottlieb, of Boston University School of Medicine, concludes "is a good health practice for a variety of reasons, and this is one more reason."
Compared with subjects who slept for seven to eight hours each night, the risk of diabetes was increased by 2.5-fold in those sleeping five or less hours, 1.66-fold for those sleeping six hours, and 1.79-fold for those sleeping nine or more hours. The corresponding increased risks of developing impaired glucose tolerance were 1.33-, 1.58-, and 1.88-fold. Blood glucose levels were not significantly affected by insomnia.
