Remaining still in cold water generates a thermal layer that makes the water feel warmer than moving around.

“The stillness is actually reducing the stimulus. If they sift around a little bit, you break up that thermal layer. That's where the real action is.”

“Now another important aspect of deliberate cold exposure that I rarely if ever hear discussed, but is vitally important is whether or not you move around or not. And here's the reason. When you get into cold water and you remain there for some period of time, your body is generating heat and that heat generates what's called a thermal layer that surrounds your entire body. So if you stay still, you are actually warmer than if you move around, you”

“If you stay still, you are actually warmer than if you move around, you can try this the next time you're doing your deliberate cold exposure.”

“If you really want to push the resilience aspect, or for instance, if you want to use a given temperature that you're comfortable in, but that you want to increase the stimulus and you want to get some more benefit for mental resilience training, well then get into the cold water, move your body around continuously, but try and keep your mind still, or even do some sort of cognitive task.”

“being very still in the cold water is actually the weaker way to go”

“if you can't get your water super cold just make the water move so if you have Jets and stuff you can turn on and anyone who's tried this and you're like okay I can do a 40 Dee bath awesome uh try 60 when the water's moving right because you break up the thermal layer normally you have a little thin layer of water that you're heating up you break that up it's a whole new world”
