#341 - Overcoming insomnia: improving sleep hygiene and treating disordered sleep with cognitive behavioral therapy for insomnia | Ashley Mason, Ph.D.

And the fewer times you wake up in the night, the fewer times you risk not falling back asleep. So little things like that can actually make a difference for waking up in the middle of the night. The other one I have about the middle of the night is a little more out there, but hear me out.

If I had five cents for every time I took away a down comforter from someone and their sleep got better, I'd have like $8. I mean, this is huge. And this is because everybody's heard of circadian rhythm, but it's missing a word. Circadian temperature rhythm. Your body is supposed to be its coolest at night and its warmest during the day.

And my favorite people to talk with about this are actually anesthesiologists. They know more about body temperature than anyone. It's remarkable. But what I've had the great good fortune of learning is that your body temperature, it's supposed to be the warmest during the day and the coolest during the night.

When we do things like trap heat with down comforters, quilted nonsense, even cotton replacement, if the word duvet is in it, comforter is in it, it's a no for me. And I give people a handout. I'm like, here's the definition of a cotton blanket. Here are links to examples of what cotton blankets are. If you are cold, buy two. Buy three. Use these.

And I'm telling you, it's made a huge difference for a lot of women in particular with night sweats. And people wake up less sometimes because they're not giving their body this message that it's time to wake up because they're not as warm. People complain about their feet and their hands. And I say, that's fine. You can put your down comforter over the foot of your bed. You can wear some socks.

But I take body temperature regulation very seriously. And sometimes it's a quick fix and we don't need a whole lot of muss and fuss. This is a very long way to answer your question, but I'll finish after this. The people at the start of the night, it's worth asking people at the start of the night if they're cold, if their hands and their feet are cold.

Slightly different. But spoiler alert, it's pretty hard to fall asleep when you have cold hands and feet. And what we have data on from some interesting research in a totally different realm is that people with extremity circulation disorders who have really cold hands and feet, they will have what we call early insomnia, which is difficulty falling asleep at the beginning of the night.

And when they get successful treatment or when you warm their hands and their feet, much easier to fall asleep. The whole warm foot bath before bed thing, that's an actual thing. Your extremities help you dump heat. So when you actually warm your hands and your feet, you can actually help dump heat from your core because you're vasodilating.
