Episode Details

Are you trading your long-term brain health for late-night screen time? Dr. Paul Chung, physician and researcher at Northwestern University, joins host Deborah Westphal to reveal why sleep is far more than rest - and why ignoring it could cost you decades of cognitive health.

Dr. Chung is an Assistant Professor at Northwestern University, a pulmonary and sleep medicine physician, and a 2023 Toffler Scholar. His research sits at the intersection of sleep, circadian biology, and Alzheimer's disease - with a special focus on adults with Down syndrome as a model for understanding cognitive decline.

What You'll Learn in This Episode

• Why sleep is an active process of repair - not passive rest - and how it regulates your heart, brain, immune system, and metabolism
• What sleep apnea actually is (beyond snoring) and why it causes a body-wide stress response every single night
• Why sleep apnea remains dramatically underdiagnosed - even 60 years after being formally defined - and what patients say when asked why they skip sleep studies
• The shocking truth: a third of adults and children still aren't getting enough sleep, and the number is even worse for teenagers
• How disrupted circadian rhythms are linked to the buildup of amyloid beta - the protein central to Alzheimer's disease
• Why individuals with Down syndrome are an invaluable research population for understanding Alzheimer's progression in the broader population
• What "slow wave activity" in sleep EEG data reveals about cognitive decline
• The science of chronotherapy - why when you take a medication or vaccine may be just as important as what you take
• Night owls vs. early birds: the genetic reality behind your body clock, and why society quietly punishes night owls
• The future of personalized sleep medicine - beyond CPAP

Key Takeaway
Sleep is the third pillar of health alongside diet and exercise - yet it's the one most people sacrifice first
