A cold plunge routine that starts with full submersion to trigger the mammalian dive reflex, then uses box breathing (four counts in, hold, out, hold) for three minutes to shift from stress to calm.
So here's how I do the cold plunge. I go right in, I dunk. So I trigger the mammalian dive reflex. That is the reflex that all mammals have. So that when they dive deep in the water and the cold water is passing over their nose, it puts them into a parasympathetic state from a sympathetic state. So it actually calms your heart rate down and makes it not so difficult. Dunking at the beginning actually does help out. And then I'll do something called box breathing. Just gentle breathing. Four seconds in, four second hold. Four seconds out, four second hold. It looks just like this. This is my drug of choice. Nice and chilly. So I'm gonna go all the way under, pop up. And now I'll just relax right here. I'll cruise for three minutes. Deep breath in, four second hold, deep breath out, four second hold. And I'll just keep tracing that square until I get to the three minutes. That's the secret.
