I've done cold plunges, but not voluntarily. When I would spend my summers away in Haiti, if I didn't want to waste my water to get warmed up, like heated by boiling water and mixing it with cold water, I would just do the cold punch style of taking a shower slash bath. So that was the way that I was doing that. And I see the benefits of it, but because I'm prone to being cold all the time, I trying to avoid that.
