How Poor Sleep Doubles Your Dementia Risk (And What to Do About It)

You already know sleep matters. But did you know that consistently poor sleep can double your risk of developing dementia — including Alzheimer's disease?

Scientists have discovered that your brain actually cleans itself while you sleep. During deep sleep, your glymphatic system flushes out toxic waste products — including the amyloid plaques linked to Alzheimer's. Miss that window night after night, and the damage accumulates.

In this episode, we break down:

• Why sleep deprivation is one of the most underrated dementia risk factors
• What happens in your brain during the hours you're unconscious
• The specific sleep habits that protect cognitive function as you age
• Practical, science-backed steps you can start tonight

Whether you're 50 or 75, it's not too late to protect your brain. The right sleep habits can make a measurable difference.
