And then if you look at, well, how long should women go?

How cold compared to men?

I think a pretty good rule is that if you get out of a cold plunge and you're like distractingly cold and having to shiver for a long period of time to heat up, you probably overdid it.

That would be the same for men and women.

I mean, unless you're literally like going for some kind of a Wim Hof

world record or just massive amounts of fat loss or something like that because you're trying to burn a bunch off with cold.

And there's better ways to lose fat than stressing yourself with excess cold.

I think just a reasonable amount of cold.

For me, my sweet spot is two to three minutes, but I go pretty cold because it's just like a time hack.

Right.

Shorter time.

Colder, shorter time.

So I do 33 degrees for two to three minutes.

And I actually like to do

pre-workout cold because you get this surge of adrenaline.

And I have an awesome workout if I get cold before the workout.

And for that, it's literally just like 30 seconds.

It's like, there's a cold plunge between me and my gym.

It's at 33 degrees.

I'll walk out there, take off my shorts, jump in, get out, towel off, put my shorts on, go into the gym.
