More REM Sleep Linked to Lower Risk of 83 Diseases, Major Study Shows

A large investigation tracking over 95,000 individuals suggests a potential link between how we sleep and the risk of developing dozens of diseases. The results indicate that different sleep stages may be associated with distinct risk profiles for various health conditions.

According to the study, participants who spent more time in REM (Rapid Eye Movement) sleep showed lower risks for a total of 83 conditions. Among the illnesses with reduced risk linked to REM sleep are dementia, heart failure, and Parkinson's disease. REM sleep is a phase of the sleep cycle characterized by intense brain activity, vivid dreaming, and rapid eye movements, and it is essential for processes such as memory consolidation and emotional regulation.

Conversely, the research also observed that longer durations of deep (slow‑wave) sleep were associated with lower risks for other specific conditions. Deep sleep is crucial for physical and mental recovery. Conditions for which greater deep sleep correlated with reduced risk include type 2 diabetes and major depression, highlighting the complexity of the relationship between sleep stages and overall health.

The findings of this extensive study underscore the importance of a deeper understanding of how sleep patterns can influence long‑term health. By correlating sleep stages with the risk of developing a remarkably wide range of diseases, the research emphasizes sleep as a factor potentially tied to the prevention and management of numerous health conditions. It serves as a reminder that sleep is a fundamental biological process, and its quality and composition can have significant implications for well‑being.
