An even more immersive option than an ice bath is whole body cryotherapy, which can only be administered by a professional in a controlled setting. Whole body cryotherapy involves being placed in a cryochamber that fully encapsulates your body, leaving only your head exposed. The air temperature in the chamber is decreased to between negative 200–300°F for about 2-4 minutes. WBC is popular with athletes for recovery, but it is being used for everything from brain and mood disorders to skin conditions.
