Whole-Body Cryotherapy Session

A brief exposure to extreme cold in a nitrogen-free electric cryotherapy chamber, cooling the ambient air to approximately minus 110 degrees Celsius. The session lasts around three minutes and is supervised by a trained technician who monitors the patient throughout.

Wellth uses an electric whole-body cryotherapy chamber rather than the older nitrogen-vapour cryosauna design. The distinction matters for several reasons. Electric chambers cool the entire room uniformly, meaning the head and upper body receive the same cold stimulus as the torso and limbs — nitrogen saunas leave the head exposed above the unit, creating an uneven thermal gradient. Electric systems also eliminate the inhalation risks associated with nitrogen gas displacement and provide more precise temperature control, typically maintaining the chamber between minus 85 and minus 110 degrees Celsius. During the session, the patient enters the chamber wearing minimal clothing — typically underwear, socks, gloves, and ear protection — and remains standing for two and a half to three minutes. A technician monitors the session through a viewing window and maintains voice communication throughout. The extreme cold triggers a systemic vasoconstriction response: blood is redirected from the peripheral circulation toward the core organs, enriching it with oxygen, enzymes, and nutrients. Upon exiting the chamber and returning to ambient temperature, peripheral vasodilation occurs, flooding the tissues with this enriched blood. The physiological cascade involves activation of the sympathetic nervous system, release of norepinephrine (which plays a role in attention, focus, and mood regulation), and a transient anti-inflammatory effect driven by reduced pro-inflammatory cytokine activity. Cold exposure also activates brown adipose tissue, which burns calories to generate heat through uncoupled mitochondrial respiration. The actual time commitment at the clinic is roughly 15 to 20 minutes including changing, the three-minute session, and a brief warm-up period. No preparation is required beyond avoiding skin lotions or moisture on the body, which can cause discomfort at extreme temperatures. Wellth recommends starting with one to two sessions per week and adjusting frequency based on individual response and recovery goals.
