Anecdata: ice plunges are a meta-cognitive skill. Several minutes in 45 F water results in a 12h+ boost in mood and good feelings in the limbs and skin, and 2-3 hours of heightened attention. I’m currently doing this ~4 times a week.

It’s the opposite of addiction’s dopamine cycle - a small pain the leads to a long-lasting high, rather than a drug’s small high that leaves you in its debt.

Do you have a cold plunge pool at home? If so, is it something you made?

I would go the cooler route if I was starting today.

I’m very lucky that a gym on my walking route to work installed a cold plunge. So I can get cardio and sauna from the same routine. (The effects in the first comment can and do come from pure plunge tho.)
Micro dosing versus macro dosing?
In my case, macro and more of it. Huberman recommends 11min per week. For better or for worse, I'm doing a little over twice that.
