Sweaty/restless at 2 a.m.? Can’t fall asleep for the first 40 minutes you’re in bed? Sick of a blaring alarm clock blasting you into a groggy morning?
Your temperature regulation key to all these scenarios.
And according to my podcast guest Dr. Michael Breus, fixing that single pattern can transform your entire night of sleep.
In today’s episode, we break down the physiology behind thermal sleep architecture and the tech that now lets you control it with precision.
Here’s what you’ll learn:
- Why a drop in core temperature signals your brain to initiate sleep and the evening habits that keep you too warm to wind down.
- What today’s mattress coolers get right (and wrong)—durability, EMFs, performance, and the science behind next-generation systems like Orion.
- How warming–cooling cycles deepen sleep, including the paradox of warm feet, pre-bed heat exposure, and the real reason “night sweats” happen.
- Michael’s travel playbook—the airplane seating tool he relies on, the hotel room setup he never skips, and the gear that keeps his rhythm consistent anywhere in the world.
If you want deeper sleep, better recovery, and mornings that actually feel restorative — this episode is worth your time.
