Improving quality of sleep is an important step in preventing the onset of type 2 diabetes.
The study recruited five men and four women between the ages of 20 and 31. The study analysed participants for two nights of uninterrupted sleep, during which they slept for 8.5 hours, to establish their normal sleep patterns.
They then observed them over a three-night study period, during which the researchers deliberately disturbed their sleep when their brain waves indicated the beginning of slow wave sleep. Young adults spend 80 to 100 minutes per night in slow-wave sleep, while people over age 60 generally have less than 20 minutes.
At the end of each study, the researchers gave intravenous glucose to each subject and took blood samples every few minutes to measure the levels of glucose and insulin. When the researchers analyzed the data they learned that the participants were almost 25 percent less sensitive to insulin after nights of interrupted sleep.
As their insulin sensitivity declined, they needed to make more insulin to process the same amount of glucose.
