A short transcript excerpt from a YouTube video by Aaron Hartman, MD about reasons people aren’t sleeping. In this segment Hartman highlights room temperature (ideally ~65°F) and cooling strategies—cool feet, cooling mats, and keeping the bedroom cool—as practical factors that influence core body temperature and sleep quality.

The other thing about it is the temperature in the room, you know, ideally about 65 degrees. I like it. Not quite that cold, but that's a huge factor. If you keep it hot, that will impact things. You know, things like core body temperature. Having your feet, like, a little cool actually affects your core body temperature, can improve sleep. That's the reason that you have these things, like these sleep mats that people. Cooling mats. And my wife actually had. Yeah, that actually helps with that. It's probably just cheaper to have your room cool than it is to buy a $2,000 chili, especially this time of year.
