Researchers have discovered that deep sleep plays a crucial role in improving blood sugar control and reducing the risk of diabetes. According to a study by the University of California (UC) Berkeley, the synchronization of deep sleep brain waves, specifically sleep spindles and slow waves, activates the parasympathetic nervous system, which helps regulate heart rate and blood vessel dilation.
Measuring changes in heart rate, the researchers found that this activation enhances the body’s responsiveness to insulin, the hormone that regulates blood sugar levels. The findings, published in the journal Cell Reports Medicine, highlight the importance of deep sleep brain waves in managing blood sugar and preventing spikes.
The study built upon previous research in rodents and revealed a previously unrecognized function of deep sleep brain waves in regulating blood sugar. The researchers also discovered that the quality and coordination of these brain oscillations during deep sleep are more predictive of glucose levels than sleep duration or efficiency.
The study included data from 600 individuals and was replicated with an additional group of 1,900 participants. The findings suggest that sleep, as a modifiable lifestyle factor, could be used in the treatment of high blood sugar and Type 2 diabetes.
Furthermore, the study opens up the possibility of developing technologies that can safely alter deep sleep brain waves to help individuals better manage their blood sugar levels. This research provides valuable insights into the role of sleep in overall health and diabetes prevention.
