I’m curious about the cold water immersion technique that is used for physical and mental health. In particular I see all these videos of people getting in lakes with ice on the surface or in bathtubs full of ice and liquid water. Nearly freezing water, so around 1c to 2c. That’s really cold. I have gone swimming in water that cold, I’m not a fan.
So how long should we be in cold water and how cold should it be? Turns out it’s longer and warmer than i thought.
According to this research review the water should be 10c to 15c and immersion should last 11 to 15 minutes.

Even wirh that knowledge it doesn’t make me want to go swimming right now.
Here in the Netherlands we have a cold water celebrity. Dives and rests in ice cold water, there’s a whole cult around him.
He happens to have an identical twin brother. (from same egg).
That brother lives an average life with just warm showers. Both are examined and the doctors could not discern a single shroud of difference between the healths of both brothers …
