Study Links REM Sleep to Reduced Risk of 83 Health Conditions
A new study published in PLOS Medicine has found a significant correlation between increased REM sleep and a lowered risk of 83 different diseases and conditions. Researchers analyzed sleep tracker data from over 95,000 individuals over one week and followed up approximately nine years later. The findings indicate that more REM sleep, the stage associated with dreaming, is linked to a reduced risk of conditions spanning blood and immune disorders, heart conditions, metabolic conditions like type 2 diabetes and obesity, gastrointestinal issues, infections, mental health disorders, musculoskeletal conditions such as arthritis, neurological conditions including Alzheimer's and Parkinson's, and respiratory illnesses. Deep sleep, the stage preceding REM, was also associated with a reduced risk of seven specific conditions: anemia, type 2 diabetes, anxiety, major depressive disorder, arthritis, Parkinson's, and sleep apnea. The study highlights the potential of readily available sleep tracker data from devices l...
