Cryotherapy chamber therapy, scientifically known as whole-body cryotherapy (WBC) or whole-body cryostimulation, is a non-invasive therapeutic modality that involves exposing the body to extremely cold air for a short duration, typically ranging from 1 to 3 minutes . The technology subjects the entire body to temperatures that can drop as low as -110°C to -195°C, depending on the device and manufacturer specifications . Originally developed in the 1970s for treating rheumatic inflammation and pain, this technology has since expanded into sports medicine, rehabilitation, and wellness applications.
Modern cryotherapy chambers utilize different technological approaches to achieve extreme cold temperatures. Some devices operate using liquid nitrogen or compressor technology to produce cold air, while others employ cascade or mixed refrigerant Joule-Thomson cycles . A key safety feature in advanced systems is maintaining optimal oxygen levels (approximately 22%) within the chamber, which allows even patients with respiratory conditions such as asthma to undergo treatment safely.
• Whole-Body Cryotherapy (WBC): This involves chambers where the entire body, except the head, is exposed to cold air. Patients enter a chamber or cabin wearing minimal clothing—typically a bathing suit or trunks—with acral parts (hands, feet, and head) covered by gloves, slippers, and a headband or mask for protection . Some advanced systems incorporate forced convection technology, generating frontal unilateral wind at speeds around 2.3 m/s at -40°C, which reduces the boundary layer of warm air around the skin and enhances heat transfer .
• Partial-Body Cryotherapy (PBC): This method involves exposing only specific parts of the body to cold temperatures, often using devices that direct cold air or nitrogen vapor onto targeted areas such as joints or muscles .
During a cryotherapy session, the body mounts a physiological "emergency reaction" to extreme cold. Blood vessels constrict (vasoconstriction), accelerating blood flow to the core to maintain optimal body temperature . This process activates the sympathetic nervous system, leading to changes in hormone and neurotransmitter levels . Research demonstrates that mean skin temperature can drop significantly—by approximately 11°C immediately following a 3-minute exposure—without reaching critically low levels that would cause tissue damage. Upon exiting the chamber, blood flows back to the periphery (vasodilation), bringing oxygen and nutrients to tissues while facilitating the removal of metabolic waste products.
The therapeutic effects of cryotherapy are mediated through multiple physiological pathways. Cold exposure triggers anti-inflammatory and antioxidant responses by increasing the body's antioxidative capacity and reducing pro-inflammatory cytokines . It also decreases nerve conduction velocity and reduces the capacity of nerve ganglia to synthesize acetylcholine, which may explain its effectiveness in relieving itch and pain . Furthermore, repeated cold exposure has been linked to endocrine and metabolic effects, including modulation of myokines such as irisin, which may have implications for metabolic health.
Cryotherapy chamber therapy has demonstrated clinical benefits across a diverse range of conditions, supported by both clinical studies and emerging research.
This represents one of the most established applications of whole-body cryotherapy. The therapy is widely used as an add-on treatment for rheumatological conditions, particularly in Eastern Europe, where it helps manage inflammation and pain . It provides significant relief for patients with chronic inflammatory joint diseases by reducing pain and improving function through its anti-inflammatory and analgesic effects
Cryotherapy is extensively utilized in sports medicine for recovery from injuries, trauma, overuse, and post-season recovery . Athletes benefit from reduced muscle soreness after intense training, with studies showing that post-exercise cold exposure can decrease perceived discomfort and accelerate recovery . The therapy also serves as a preventive strategy against the deleterious effects of exercise-induced inflammation . Some evidence suggests that cryotherapy performed approximately three hours before competition may enhance athletic performance by regulating hormones such as testosterone and cortisol, and by modulating neurotransmitter activity.
Clinical research has demonstrated the efficacy of whole-body cryotherapy for inflammatory skin diseases. In a study of patients with atopic dermatitis, twice-weekly cryotherapy sessions over four weeks produced significant improvements . The mean Scoring of Atopic Dermatitis index (SCORAD) decreased by 19.6%, transepidermal water loss improved by 19.4%, and patients reported a 32.6% reduction in pruritus (itch) and a 37.5% improvement in sleep disturbances . The therapy demonstrated a steroid-sparing effect, as it was successfully administered as monotherapy without concurrent anti-inflammatory topical preparations.
Emerging evidence supports the use of cryotherapy in managing various neurological and psychiatric disorders . Clinical applications have been documented for multiple sclerosis, Parkinson's disease, and spasticity, where the therapy may help reduce pain and fatigue while improving function . Patients with fibromyalgia have also reported benefits, including pain reduction and improved quality of life . Additionally, cryotherapy has been associated with improved mood, reduced stress, and enhanced psychological well-being, which may be particularly valuable for individuals with mood disorders or those seeking mental wellness support.
Recent research has unveiled significant metabolic effects of chronic exposure to cryogenic temperatures . Whole-body cryostimulation represents cutting-edge research in the management of obesity and diabetes . Exposure to cold mimics certain aspects of exercise by affecting myokine expression, which may have therapeutic implications for metabolic diseases . The therapy may influence energy consumption by activating brown adipose tissue, which helps the body burn fat to maintain temperature homeostasis.
Cryotherapy has shown promise in addressing post-viral conditions, including post-COVID-19 and long-COVID symptoms . Patients have reported improvements in fatigue, mood, and quality of sleep following treatment . The therapy is also used for general health improvement and biological regeneration, with proponents citing enhanced recovery, reduced stress, and improved overall functioning.
