What does cryotherapy feel like?

A whole-body cryotherapy session lasts 2 to 3 minutes in a chamber cooled to between -110 degrees C and -140 degrees C using liquid nitrogen or electrically cooled air. You enter the chamber wearing minimal clothing — typically underwear, plus mandatory dry socks, gloves, ear protection, and sometimes a face mask. The initial sensation is a sharp, intense cold that is startling for first-time users but becomes more manageable with experience. Most people describe it as an extreme version of jumping into a cold lake. Within the first 30 to 60 seconds, your skin temperature drops rapidly and you will feel strong tingling and tightness across your body. The second minute is usually the most challenging as the cold intensifies, and many centers play music or encourage conversation to help pass the time. By the third minute, some people report a mild numbing sensation. Upon exiting, you will feel an immediate rush of warmth as blood flow returns to your extremities. Many users describe a surge of energy and endorphins — similar to a runner's high — that can last several hours. Skin redness is normal and typically fades within 15 to 30 minutes. First-time users often start with shorter 2-minute sessions before progressing to the full 3 minutes.

About Cryotherapy

Exposure to extreme cold (-110°C to -140°C for 2-3 minutes) triggers peripheral vasoconstriction, norepinephrine release, and cold shock protein activation.
