Cryo­therapy

Extreme Cold.
Rapid Stimulus.

Cryotherapy is whole-body exposure to extreme cold temperatures — typically between -110°C and -140°C — for a short, precisely controlled duration of two to three minutes. Unlike cold water immersion, which achieves its effects through thermal conduction in water, cryotherapy operates through a cold air environment that surrounds the entire body simultaneously, producing a systemic stimulus that activates the body's cold-response mechanisms without the same thermal load.

The distinction matters. Cold water immersion at 6°C over three minutes produces a different stimulus profile than cryotherapy at -120°C for two minutes. Both activate cold-response pathways. The mechanisms and downstream effects have similarities and differences that make them complementary rather than interchangeable recovery tools.

How Cryotherapy Works

Cryotherapy chambers use liquid nitrogen or refrigerated cold air to rapidly drop the ambient temperature of the chamber environment. The user enters the chamber — typically a walk-in cabin — wearing minimal protective clothing to maximise skin surface area exposed to the cold. The two-to-three minute exposure is sufficient to trigger a profound cold stimulus across the entire body surface area simultaneously.

The skin surface cools rapidly but core temperature changes are minimal during the brief exposure — the body's thermoregulatory response is activated but does not have sufficient time to produce significant core cooling. The stimulus is primarily peripheral: cold receptors across the skin surface fire simultaneously, triggering a whole-body sympathetic response and a powerful release of norepinephrine and other stress response hormones.

The post-exposure rewarming phase produces the primary therapeutic effects: vasodilation, blood flow increase into cooled peripheral tissues, and a systemic anti-inflammatory response that continues for hours following the session.

Anti-Inflammatory Effects

The whole-body anti-inflammatory response produced by cryotherapy is one of its primary applications in professional sport. Following exposure to extreme cold, pro-inflammatory cytokine production is downregulated while anti-inflammatory mediators are upregulated. This systemic shift in the inflammatory profile is beneficial for athletes managing the chronic low-grade inflammation associated with high training volume.

The effect is not identical to localised icing or cold water immersion. Whole-body cryotherapy produces a systemic inflammatory modulation — affecting the entire body's inflammatory state — rather than a localised effect on specific muscle groups. For athletes who are managing total-body training load or who need to manage inflammation across multiple sites simultaneously, this systemic effect is directly relevant.

Cryotherapy vs Cold Water Immersion

Both modalities activate cold-response pathways. The practical differences are relevant to session planning. Cold water immersion at 4–6°C produces stronger local cooling of the muscles, particularly in the limbs, and the hydrostatic pressure of the water adds a compression component that cryotherapy does not provide. Cryotherapy produces a more uniform whole-body surface stimulus and tends to produce a more intense acute systemic response in a shorter duration.

For many athletes, cryotherapy is used as an alternative to cold water immersion when time is limited — the two-to-three minute exposure delivers a meaningful stimulus in a session that might not accommodate a ten-minute ice bath. It is also preferred by some athletes who find full cold water immersion psychologically harder to tolerate, as the short duration and dry environment makes it more accessible.

Used within a complete protocol, both have a role. The modalities are complementary — cryotherapy for the systemic cold stimulus, cold water immersion for the local muscle cooling and compression effect. At Nomadic, both are available as part of the full recovery stack.

Performance and Recovery Benefits

• Systemic anti-inflammatory response lasting hours post-exposure
• Norepinephrine release supporting mood, energy, and focus
• Reduced delayed onset muscle soreness in post-exercise protocols
• Accelerated recovery of performance capacity between training sessions
• Whole-body cold stimulus in a two-to-three minute duration
• Management of chronic low-grade inflammation in high-volume training
• Accessible cold exposure for athletes who find water immersion challenging

Who Uses Cryotherapy

Professional and semi-professional athletes across all disciplines. AFL clubs, rugby programs, elite cycling, athletics — cryotherapy has been a standard recovery facility component in professional sport for over a decade. Outside professional sport, competitive amateur athletes in any discipline that produces significant training load benefit from the same stimulus. It is particularly relevant for athletes managing chronic inflammation, in tournament or competition schedule with compressed recovery windows, or in intensive training blocks where daily recovery quality is critical.
