But if you're like shivering, hyper cold, that's too much physiological excitement before bed.

And there's no reason you couldn't do both.

So it just kind of depends on how cold we're talking.

Like a lot of times since I'm playing tennis or pickleball or doing something fun with my kids in the evening before dinner, a lot of times like right before dinner, I'm just getting into a lukewarm shower or even jumping into the hot tub and letting the ambient air cool me off, which kind of cools you a little bit.

Not my wife.

My wife's a freaking furnace.

She's so hot.

Like a lot of times, like I'll get, sometimes I'm cold, I'll snuggle up to her and I'll just be like,

But in the evening, I'll do like kind of cold and in the morning, really cold.

warm within a couple of minutes.

And the general rule for sleeping temperature is that like when you get into bed or you take off your clothes to get in the bed, you want to feel like a mild cognitive resistance because it's just a little bit cold, but it's not freezing, shivering cold.

I actually interviewed this doctor.

She's called the thyroid fixer doctor on my podcast.

This is fresh in my mind because that podcast came out like three days ago.

It's just like, okay, this is going to take me a few minutes to warm up or snuggle up with my husband or wife or lay in bed and get warmed up a little bit.

Her name is Dr. Amy Horniman.

And she talked about this little known molecule called T2.

It's not what you find in thyroid medications.
