So although some people feel like the cold wakes them up, you know, and so my husband –

I don't know if he's an outlier, but he likes to cool his body down.

Not like right before.

I mean, we're talking like a couple of hours.

Yes.

And the same goes with the sauna.

You want to do it a couple of hours before your bedtime because you want to cool down first.

And so what I like to do is I'll do a hot tub or a sauna a couple hours before bed and then I hit the cold shower to cool myself down.

Interesting.

Yes.

Well, I think, for example, the beta-hydroxybutyrate might come into play there and also, again, the cold exposure.

So for athletes that are like high-level elite, there are studies showing that cold exposure even done before, for example, like tennis players or kayaks, another one, if they do cold exposure before like a race, it actually improves performance.

As well, and that probably because it's lowering inflammation there's an acute response of lowering inflammation inflammation can also play a role in cognitive function anxiety in focus and attention.

You know all these things, but I would say the the beta hydroxy butyrate is sort of the the health hack that I would go to because.

Again it's being used as a really clean source of energy.

You also want to be able to make fast decisions, right?

Whether you're a football player or a tennis player or whatever, you want your brain to be able to make those decisions quickly.

That's something that's going to happen.

And then lowering the anxiety as well.

So I think all those sort of point to why, you know, taking an exogenous ketone may help.
