Sleep quality has been associated with various diseases, such as dementia and diabetes. Scientists know about a causal relationship between inadequate sleep and impaired regulation of blood glucose levels. While good sleep has been found to enhance glucose metabolism and improve overall blood sugar control.

But the reason behind it continues to elude us!

With a new study, researchers at the University of California are a step closer to understanding the significance of sleep-in blood glucose control. Their recent study sheds light on the role of brain wave patterns generated during deep sleep.

Deep sleep is an important stage of sleep characterized by slow brain waves. It plays a crucial role in memory consolidation, hormone regulation, and overall brain health.

Why is a lack of quality sleep considered to increase the risk of diabetes?

In this study, the correlation between blood sugar control and deep sleep brain waves was examined. The findings revealed that individuals who exhibit better blood sugar control tend to have more stable and elevated levels of deep sleep brain waves.

In a comprehensive analysis of sleep data from 600 participants, researchers discovered that a robust and frequent synchronization of slow waves and spindles in the brain resulted in the activation of the parasympathetic nervous system (PNS). This network of nerves induces relaxation in the body after periods of stress or danger, as evidenced by variable heart rate.

The study revealed that PNS activation enhanced the body’s responsiveness to insulin, the hormone responsible for regulating glucose levels. Consequently, the cells were more efficient in absorbing glucose from the bloodstream, effectively averting a surge in blood glucose levels.
