You snooze, you win? A new study reveals that poor sleep habits in your 40s could accelerate brain aging by up to 2.6 years by the time you reach your 50s. Published in Neurology, the study suggests that quality sleep is crucial for maintaining brain health and reducing dementia risk as we age.
Researchers from the University of California, San Francisco, monitored sleep habits in 589 adults over 10 years, using MRI scans to estimate brain age. They found that individuals with three or more poor sleep traits—like frequent awakenings and trouble falling asleep—had a brain age 2.6 years older than those with healthier sleep patterns.
Experts stress that quality sleep supports brain health, reduces inflammation, and boosts the immune system. Dr. Kristine Yaffe, a co-author of the study, emphasized the key to good sleep hygiene, such as maintaining a consistent sleep schedule and avoiding caffeine and electronics before bed.
The findings underscore sleep’s role in overall health. Experts recommend regular exercise, a cool, dark bedroom, and tech-free evenings to promote a restful night.
