I do it much longer at a warmer temperature.

And the data there, there's a few things.

There's anecdotal data about affecting menopause hot flashes.

I've seen good data with those with joint pain, rheumatoid arthritis, systemic inflammation.

The data that I would say I'm watching emerge is there seems to be an impact on the central nervous system.

There seems to be an impact with dopamine release.

There is also a way in which I think that you can – there's nothing more painful than a really cold plunge.

I mean, it just is.

It's shocking, and it does seem to affect mood in a positive way for people.

Also, there seems to also be somewhat of an adrenaline dump for other people.

It can make them exhausted.

Again, I think it's very important to parse out what is the scientific evidence, where is the scientific evidence strongest.

Scientific evidence is strongest with a larger body of literature for saunas.

For even people that can't do cardiovascular activity, it acts as almost an exercise mnemonic versus the cold plunging seems to, I think we're going to start to see more and more data from a systemic inflammatory response, from there's even some data about browning of fat.

Again, is this human models?

I cannot say.

That is not the reason I do it.

Anecdotally, my patients tell me that it makes them leaner.

But what it does do is it seems to really help reset the nervous system in a very short period of time.

If you are having the worst day and cannot get out of your own way, nothing is more effective than the cold plunge.
