A good night’s sleep may help control blood sugar

In the deepest stage of sleep, slow waves of electrical activity travel through your brain. They help consolidate memories and flush out the buildup of unwanted chemicals, getting you ready for the day. This midnight orchestra is responsible for many of the benefits of a good night’s sleep, such as improved attention, mood and energy levels.

Scientists at the University of California, Berkeley, recently found that for some people, these waves could also serve as early warning signs of diabetes. The results, published in July in Cell Reports Medicine, suggest that getting a restful sleep may help control high blood sugar.
