- More naps, higher risk? Research links daytime sleep to health warnings in aging adults
A study by Mass General Brigham found that excessive daytime napping in older adults is linked to higher mortality risk. Using wrist-worn trackers, researchers observed that longer, more frequent naps—especially in the morning—correlated with increased mortality, suggesting potential early signs of health decline. However, the study notes correlation does not imply causation.
