Deep-sleep brain waves predict blood sugar control

New findings from the University of California, Berkeley suggests that deep-sleep brain waves at night play a role in regulating the body's sensitivity to insulin, improving sugar control the following day. The combination of two brain waves, sleep spindles and slow waves, increases the body's sensitivity to insulin, leading to lower glucose levels. This discovery could potentially be used as a therapeutic treatment for individuals with high sugar or Type 2 diabetes. Additionally, these deep-sleep brain waves could serve as an indicator of a person's next-day sugar levels, making them a valuable tool for mapping and predicting sugar control. The research, published in Cell Reports Medicine, reveals a new role for deep-sleep brain waves in managing sugar and complements previous studies that showed their role in learning and memory. The researchers analyzed sleep data from 600 individuals and found that the coupling of deep-sleep brain waves predicted next-day glucose control better than sleep duration or quality.
