Good sleep may help prevent diabetes
These days people are looking for ways to cut their risk of developing diabetes and, it turns out, getting enough sleep may help. That’s the conclusion of a study at the Los Angeles Biomedical Research Institute. The researchers also found that the body's ability to clear glucose from the bloodstream improved after three nights of "catch-up sleep" on the weekends in men with sleep deprivation during the work week.
The research term studied 10 non-diabetic men, average age 28.6, who reported a period of six months or longer of inadequate sleep during the work week. On average, the men received 6.2 hours of sleep each weeknight, though they reported catching up on weekends, sleeping an extra 2.3 hours per night.
The men in the study spent consecutive weekends in a sleep lab hooked up to monitoring devices. The researchers randomly assigned the men to two of three sleep conditions: (1) 10 hours of sleep, (2) six hours of sleep or (3) 10 hours in bed, in which noises during deep sleep aroused them into shallow sleep without waking them.
Blood was drawn at the end of the study period, and it was determined that the men who slept 10 hours a night in catch-up sleep exhibited better insulin sensitivity than those who had persistent sleep restrictions. Insulin resistance can be a precursor of type 2 diabetes.
