Sleep Unplugged with Dr. Chris Winter

Every June, thousands of sleep researchers descend on one city and quietly rewrite what we think we know about a third of our lives. This year it was Baltimore's turn, for the 40th annual SLEEP meeting — and the data that came out of it hits closer to home than usual: blood pressure, diabetes, teenage phones, and why "night owl" might really mean "lonely." Here are my Top 10 studies from SLEEP 2026 most likely to actually change how you sleep. In this episode we will:
Break down why being sleepy and wired at night is a uniquely dangerous combination for blood pressure — and why either symptom alone barely moves the needle
Sit with a staggering number out of Yale: veterans with both insomnia and sleep apnea face six times the risk of developing type 2 diabetes
Revisit the "regularity beats duration" thread from Episode 209 with two brand-new studies — one in preschoolers, one tracking teens all the way to age 22
Unpack why women's sleep apnea can look identical to men's on paper and feel completely different in the body, and why that's delaying diagnoses
Get into the psychology of sleep: why night owls' anxiety may really be about nighttime loneliness, and why expecting bad postpartum sleep can help create it

The Sleep Solution and The Rested Child
Thanks for listening and sleep well!

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

The Sleep Solution and The Rested Child
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
