Your first sixty seconds in the cold

If this is your first ice plunge, you are about to do something the body has spent fifteen years trying to talk you out of. That is part of the point.

The most common mistake is to lower yourself in slowly, in stages, while holding your breath. The body reads this as a controlled emergency and responds in kind — heart rate spikes, shoulders climb to the ears, the lungs grab the smallest possible breath and hold it. You'll be miserable for ninety seconds, and you won't get the dose.

The thing that works, every time, is faster than you want it to be. Step in. Sit down. Exhale, slowly, all the way out. Then take the next breath through pursed lips, long and slow.

The first ten seconds are the loudest. The skin sings. The shoulders try to climb. You let them try, and you keep breathing out longer than you breathe in. By twenty seconds, the body has updated its read on the situation and stopped firing the alarm. By thirty, you are doing it on purpose.

For first-timers, sixty seconds is the number we suggest — not because it's the right dose, but because it's a number you can count to without negotiating with yourself. Most people stay longer. Some stay much longer. There is no medal for it, and the chemistry doesn't care.

When you climb out, walk. Don't run. The afterglow takes thirty seconds to land. It's worth the wait. By the time you reach the jacuzzi you will feel it — the flush, the focus, the laugh you didn't know was in there.

Then the only question is how soon you go back in.
