While you rest, your brain gets to work. During deep, slow-wave sleep, the brain clears out waste including beta-amyloid, a protein linked to Alzheimer's. Research connects consistent, quality deep sleep with stronger memory resilience, while ongoing poor sleep is associated with a faster buildup of that protein over time.
It isn't a cure or a guarantee, but protecting your sleep is one of the simplest things you can do for long-term brain health. If you or someone you love struggles to sleep well, it's worth a conversation with your doctor.
