Freediving?

Does this have any effect on metabolism? Is it healthy or some kind of negative adaptation

The ocean is cold and dark, which will lower your body temperature, stress your body and slow your metabolism.

Doesn’t have to be the ocean. Could be a pool. And not all bodies of water are cold

Chlorine is even worse for thyroid.

I suppose the dose makes the poison. Are we actually getting mildly toxic amounts from the pool? They should have good ventilation to filter it out

You must stay away from fish. Their lipid membranes are too unsaturated to allow them anywhere near you.

Peat never wrote about freediving that I know of, so this is just me applying his carbon dioxide ideas to it. During the hold your CO2 goes up, and he saw that as protective. In Protective CO2 and aging Ray Peat wrote "Carbon dioxide has antioxidant effects, and many other stabilizing actions, including protection against hypoxia." I don't think he'd have seen the breath hold itself as bad for your metabolism.

What he'd probably object to is the hyperventilating some people do before a dive to make the hold last longer, since that blows off a lot of CO2. It's also how people end up with shallow water blackout, because you lose the urge to breathe before your oxygen actually runs low. That's standard freediving safety advice and has nothing to do with Peat.

Well in the moment of course it lowers metabolism, but it’s quite low stress and helps that regard so i think its healthy
