Sleep Unplugged with Dr. Chris Winter

Deep sleep and REM sleep get lumped together as "good sleep," but they're almost opposite states — one is the quietest your brain gets all night, the other is nearly as active as being awake. In this episode we pull the two apart: how we stumbled onto each of them, what's happening chemically while they run, and why one of them quietly shrinks as we age while the other holds steadier. In this episode we will:
Break down what's actually happening in slow-wave sleep versus REM — brainwaves, muscle tone, and why one is a "quiet body, quiet brain" state and the other is "quiet body, active brain"
Trace the history back to 1953, when a University of Chicago graduate student stumbled onto REM sleep almost by accident
Get basic on the neurochemistry: the GABA-driven shutdown that produces deep sleep, and the acetylcholine surge that flips REM on
Bring in new data from SLEEP 2026 in Baltimore, including a 22-million-night wearable dataset showing how deep sleep changes across adulthood, and a mattress-temperature study that moved the needle on restful sleep by nearly 20 minutes a night
Cover what actually protects deep sleep — and what quietly wrecks it, from alcohol to late caffeine to a bedroom that's too warm

Thanks for listening and sleep well!

We tend to think of insomnia and sleep apnea as two completely different sleep disorders. One means you can't sleep. The other means you stop breathing. Simple, right? Not so fast. In reality, many people with sleep apnea don't complain about snoring or excessive daytime sleepiness. Instead, they complain that they wake up repeatedly throughout the night and can't stay asleep. In this episode we will:
Explain why sleep apnea often causes insomnia-like symptoms rather than daytime sleepiness 
 Explore the growing recognition of COMISA (comorbid insomnia and sleep apnea) 
 Discuss why women and non-traditional sleep apnea patients are especially likely to be misdiagnosed 
 Review the latest research on treating insomnia and sleep apnea together

This week marks the 12th month we have put out the Top 10 Sleep Threats Power Rankings, and this week, we have a special guest assessor, Upneet Chawla, MD (@sleeping.beauty_md). Upneet is an internist and board-certified sleep specialist.  In this episode, she has graciously provided us her list. In this episode we will:
Find out what Dr. Chawla thinks are the top threats to your sleep
Incorporate abstracts from the 2026 Sleep meeting to illustrate her points

Sleep duration has always been the headline number in sleep science, but mounting research is pushing the conversation toward something less obvious: how consistent your timing is from night to night. In this episode we dig into a debate that's far from settled, and into a statistical trap that may be quietly distorting it. WIn this episode we will:
Break down the four separable pillars of sleep health: duration, consistency, continuity, and circadian alignment
Walk through the landmark UK Biobank study showing sleep regularity outpredicting duration for all-cause mortality
Bring in brand-new data from SLEEP 2026 in Baltimore linking sleep consistency to long-term cardiovascular trajectories
Expose the "range restriction trap," why duration looks less important in these studies largely because almost nobody in them was severely sleep-deprived for years on end
Stress-test the theory with five hypothetical sleepers, each excelling at one dimension and failing at another, to figure out which variable really wins when you push it to the extreme

Menopause has always been linked to sleep disruption, but the story has changed dramatically since we last covered it in episode 3. Hot flashes and night sweats still matter, but newer research is pushing us to think more broadly about brain temperature regulation, insomnia, mood, sleep apnea, cardiometabolic risk, and a new generation of nonhormonal medications that directly target vasomotor biology. In this episode we will:
 Revisit why menopause so often produces sleep-maintenance insomnia 
 Explore the KNDy neuron/neurokinin pathway and why drugs like fezolinetant and elinzanetant matter 
 Separate hot-flash awakenings from true insomnia disorder 
 Discuss CBT-I, hormone therapy, and nonhormonal treatment options 
 Explain why sleep apnea and cardiometabolic risk should not be overlooked in midlife women
