Study Links Poor Sleep in 40s to Accelerated Brain Aging

Research suggests that inadequate sleep quality may age the brain by nearly three years, impacting cognitive health in middle age.

A study published in Neurology found that poor sleep quality in middle-aged adults is associated with signs of accelerated brain aging.
Participants with multiple poor sleep characteristics had brains up to 2.6 years older than those with better sleep habits.
Key sleep issues linked to faster brain aging include poor sleep quality, difficulty falling and staying asleep, and early morning awakening.
Researchers emphasize the importance of addressing sleep problems early to preserve brain health and reduce risks of cognitive decline.
The study highlights the need for consistent sleep schedules, regular exercise, and avoiding caffeine and alcohol before bed to improve sleep quality.
