This reminds me of a thing I do when I prepare for a cold shower. I rhythmically start walking in place. Just moving my weight from one foot to the other at a constant pace. At the same time, I breathe in and out at the same pace. I've noticed this helps me take the shock of the cold water so much better. I feel like it helps my emotional mind latch onto a simple task. It's like when you're air drumming and you nail all of the parts in a song and you feel great because there's something so satisfying about your mind predicting an outcome and then that our coming happening rhythmically. I feel it's the same but on a simpler scale when doing my steps and breathing.
