Struggle sleeping? These three common sleep habits are tied to signs of brain aging

Article excerpt

A University of Arizona study links three common sleep habits to signs of brain aging. Researchers discovered that how people sleep, not just how much, may have lasting impacts on brain health over time. The findings suggest that certain sleep behaviors accelerate cognitive decline and structural changes in the brain associated with aging. While the study doesn't yet identify which specific habits are most harmful, it adds to growing evidence that sleep quality matters as much as sleep quantity for long-term neurological health.
