  1. The study analyzed data from over 95,000 people who wore wrist accelerometers for seven consecutive days and nights.

  2. Greater amounts of REM and deep sleep were associated with lower risks of dozens of diseases.

  3. People who slept less than 5 hours a night had an increased risk of 37 conditions.

  4. The study found that maintaining a consistent sleep schedule can help reduce the risk of many diseases.

More REM Sleep Linked to Lower Risk of Many Diseases

Topic: Health

A new study found that people who sleep more during their REM stage have a lower risk of getting many diseases. The study looked at data from over 95,000 people and found that sleeping less than 5 hours a night is linked to a higher risk of disease.

A recent study published in the journal PLOS Medicine has made an important discovery about sleep and health. Researchers led by Shengzhi Sun from Capital Medical University in China analyzed data from over 95,000 people who wore wrist accelerometers for seven consecutive days and nights. The researchers used a deep-learning algorithm to calculate sleep stages, including REM (rapid eye movement) sleep, deep sleep, and light sleep.

The study found that greater amounts of REM and deep sleep were associated with lower risks of dozens of diseases. In fact, people who slept more during their REM stage had a 74% lower risk of heart failure, a 54% lower risk of dementia, and a 20% lower risk of Parkinson's disease.

The researchers also found that sleeping less than 5 hours a night is linked to a higher risk of disease. People who slept in this range had an increased risk of 37 conditions, including anxiety and substance use disorders.

However, the study cannot prove that sleep patterns directly cause disease risk. The findings suggest that maintaining a consistent sleep schedule and getting enough sleep can help reduce the risk of many diseases.

Why It Matters

This research is important for Indians because it highlights the importance of getting enough sleep to stay healthy. With many Indians facing sleep deprivation due to busy lifestyles, this study's findings can serve as a reminder to prioritize sleep and maintain a healthy lifestyle.
