This is me taking an ice bath in our bath tub. In the background, the timer shows nine minutes.

What I Love About Ice Baths

The nurse took the temperature under my tongue. “Your temperature is 93°F! That’s not good,” She said.

Normal body temperature is 98.6F. The life-threatening emergency medical condition known as hypothermia is defined as the core body temperature dropping below 95°F. I was technically hypothermic.

“Wait, your pulse is 33! That’s not possible. I’m not even going to write that down.” She continued, before rushing out of the room to bring in a physician’s assistant. He ran all the tests again. When I stopped talking to him, my pulse slowed back down to 33 again.

“I thought my resting pulse rate was low.” he said, “It’s in the fifties because I run a lot.”

“Mine is usually about 38 bpm.” I said, “I meditate a lot.”

“How are you feeling? Do you feel light-headed?” He asked me, looking very concerned.

I responded, “No, I feel fine.” I felt great: calm, relaxed, clear minded, and focused.

“Well, your blood oxygen level is 100%, so you have good profusion,” he said, with some relief.

I had already told them more than once, including just after I arrived for the routine test, that only twenty minutes earlier I had gotten out of a 15-minute ice bath at 41°F (5°C). It takes some time for the body to warm up again.
