Poor Sleep Raises Blood Glucose Levels
Science has again shown the importance of a good night's sleep. Twenty-one people without diabetes got only six hours of shut-eye a day, at odd hours, for three weeks. By the end, their sleep-deprived bodies were making an average of 32 percent less insulin after a meal than they did at the study's start, leading to higher blood glucose that reached prediabetic levels in some people. What's more, the drowsy participants ended up with a lower metabolic rate, which would translate into a weight gain of almost 13 pounds over a year, the researchers say. After a nine-day recovery period, participants' blood glucose and metabolism returned to normal. These findings suggest a link between sleep schedules, obesity, and type 2 diabetes.
