What Happens During Whole Body Cryotherapy

Whole body cryotherapy (WBC) involves standing in a chamber cooled to extreme temperatures, typically between -110°C and -160°C (-166°F to -256°F), for 2 to 4 minutes. The exposure triggers a systemic cold stress response: blood vessels constrict, your nervous system activates, stress hormones surge, and anti-inflammatory processes kick in.

Two types of chambers exist. Cryosaunas (also called partial-body cryo) use liquid nitrogen to cool a single-person chamber from the neck down; your head stays above the chamber in ambient air. Walk-in cryochambers cool the entire room, including the air you breathe, using electrical refrigeration. Walk-in chambers are considered more consistent and allow exposure of the whole body, including the head and face.

The practice has grown rapidly since the early 2010s, with cryotherapy studios now common in most major cities. But which claims hold up to scientific scrutiny? For a broader overview of the therapy, visit our cryotherapy guide.

The Physiology of Extreme Cold Exposure

When your body encounters extreme cold, several things happen in rapid sequence:

Peripheral vasoconstriction: Blood vessels in the skin and extremities constrict sharply, redirecting blood toward the core. This is a protective mechanism to preserve core temperature.

Norepinephrine release: Cold exposure triggers a significant spike in norepinephrine (noradrenaline), often 2-3x baseline levels. This catecholamine is both a neurotransmitter and hormone that affects attention, mood, pain perception, and inflammation.

Endorphin release: The cold stress activates endogenous opioid pathways, producing a natural analgesic and mood-elevating effect that many users describe as a “high” or euphoria after exiting the chamber.

Anti-inflammatory signaling: Studies show reductions in pro-inflammatory cytokines (IL-1β, TNF-α, IL-6) and increases in anti-inflammatory cytokines (IL-10) following WBC sessions.

Post-exposure vasodilation: After leaving the cold, blood vessels reopen and blood rushes back to the periphery, carrying oxygen and nutrients. This “flushing” effect is part of the recovery benefit.

Benefit #1: Post-Exercise Recovery

Athletic recovery is the most heavily marketed and most studied use of WBC. The rationale is straightforward: intense exercise causes microtrauma, inflammation, and oxidative stress in muscle tissue. WBC reduces inflammation and may accelerate the recovery process.

The evidence is mixed but leans positive. A 2017 Cochrane review found limited evidence that WBC reduced muscle soreness after exercise compared to passive rest, but the effect sizes were small and study quality varied. More recent research has been more favorable. A 2022 meta-analysis in Sports Medicine found that WBC significantly reduced subjective muscle soreness and improved perceived recovery, particularly when used within 1-2 hours of exercise.

What the research consistently shows:

Reduced subjective muscle soreness (DOMS) ratings
Improved perceived recovery
Reduced creatine kinase levels (a marker of muscle damage) in some studies

What remains less clear:

Whether WBC actually accelerates tissue repair or just reduces the perception of soreness
Whether it provides meaningful benefit over cold water immersion (ice baths), which is much cheaper

WBC vs. Cold Water Immersion
Ice baths (10-15°C for 10-15 minutes) have a longer research history and stronger evidence base than WBC for post-exercise recovery. WBC is more comfortable for most people (dry cold feels less intense than wet cold) and takes less time. Head-to-head studies show similar outcomes for muscle soreness, with neither method showing clear superiority. Ice baths cost almost nothing; WBC costs $40-100 per session.

Benefit #2: Pain Relief and Inflammation Reduction

WBC shows genuine promise for short-term pain relief. The combination of norepinephrine release (which modulates pain signaling), endorphin production, and local nerve conduction slowing creates a multi-pathway analgesic effect.

Conditions where WBC has shown pain-relieving effects in clinical studies:

Rheumatoid arthritis: A 2008 study in the journal Rheumatology International found that 10 sessions of WBC significantly reduced pain and disease activity in RA patients
Ankylosing spondylitis: WBC improved pain scores and spinal mobility in a controlled trial
Fibromyalgia: Mixed results; some studies show benefit for pain and quality of life, while others show no significant difference from control
Osteoarthritis: Short-term pain relief documented in several small studies

The anti-inflammatory effect appears real but temporary. Cytokine changes typically last 1-3 hours after a session. Cumulative benefit may build over multiple sessions, but the evidence for lasting anti-inflammatory effects beyond the treatment period is thin.

Benefit #3: Mood and Mental Health

This is one area where the subjective experience and the science actually align well. The norepinephrine surge from cold exposure has clear neurological effects on mood, alertness, and focus. Users consistently report feeling energized, alert, and positive after WBC sessions.

A 2008 study in Medical Hypotheses proposed WBC as an adjunct treatment for depression, based on the cold-induced activation of the sympathetic nervous system and the dense network of cold receptors in the skin that, when stimulated, send electrical impulses to the brain. A subsequent pilot study found that WBC improved depression and anxiety scores in patients with mood disorders.

The mood benefit is one of the most reproducible effects of WBC and does not require belief in any elaborate mechanism. Cold stress reliably produces norepinephrine and endorphins. These neurochemicals improve mood. The effect is acute and real.

Benefit #4: Skin Conditions

Some preliminary research suggests WBC may benefit certain skin conditions:

Atopic dermatitis: A small study found improved skin barrier function and reduced itching after repeated WBC sessions
Psoriasis: Case reports and one small study suggest possible improvement, likely through immune modulation

This area of research is very early-stage. No dermatological society recommends WBC as a treatment for skin conditions based on current evidence.

Claims vs. Evidence: An Honest Breakdown

Claimed Benefit	Evidence Level	Reality Check
Post-exercise recovery	Moderate	Reduces perceived soreness; unclear if it speeds actual tissue repair
Pain relief	Moderate	Short-term analgesic effect is real; lasting pain reduction requires ongoing sessions
Mood improvement	Moderate-Strong	Norepinephrine and endorphin response is well-documented
Anti-inflammation	Moderate	Acute cytokine changes observed; long-term systemic effects unproven
Weight loss / metabolism boost	Weak	Caloric burn from a session is minimal (50-80 calories). Brown fat activation is real but the metabolic impact is small.
Immune boosting	Weak	Some studies show transient white blood cell changes; no evidence of reduced illness
Anti-aging / collagen production	Very Weak	No credible evidence. Marketing claim without scientific support.
Cellulite reduction	Very Weak	No credible evidence. Marketing claim.

The Bottom Line on Weight Loss Claims
Some cryotherapy studios advertise “burn 500-800 calories per session.” This is misleading. Research shows a 2-4 minute WBC session burns approximately 50-80 extra calories. Your body does activate brown adipose tissue and increase metabolic rate after cold exposure, but the magnitude is modest. WBC is not a weight loss intervention. If a studio makes dramatic calorie-burning claims, treat their other health claims with similar skepticism.

Who Gets the Most Benefit?

Based on the available evidence, WBC offers the most value for:

Athletes and serious exercisers who train at high volume and need to recover between sessions. Professional sports teams use WBC precisely because even marginal recovery improvements matter at elite levels.
People with inflammatory joint conditions (rheumatoid arthritis, ankylosing spondylitis) who are looking for adjunctive pain relief alongside their standard medical treatment.
Those seeking a mood boost or stress relief tool as part of a broader wellness routine. The endorphin and norepinephrine effects are reliable and enjoyable.

WBC offers less value for people primarily seeking weight loss, anti-aging, or immune enhancement. The claims in these areas significantly outpace the evidence.

Safety and Contraindications

WBC is generally safe when performed at a professional facility with proper equipment and trained operators. Serious adverse events are rare but have been reported:

Frostbite or cold burns (usually from wet skin/clothing or malfunctioning equipment)
Transient blood pressure elevation
Asphyxiation risk in nitrogen-cooled cryosaunas (a death was reported in 2015 when an employee used a cryosauna alone after hours)

Contraindications include: uncontrolled hypertension, Raynaud’s disease, cold urticaria, cold agglutinin disease, untreated cardiac arrhythmias, acute cardiovascular or respiratory disease, and seizure disorders.

Frequently Asked Questions

How often should I do whole body cryotherapy?

For general wellness and mood, 1-3 times per week is typical. Athletes during heavy training blocks may go daily. There is no established maximum frequency, but most facilities recommend at least 24 hours between sessions.

Is WBC better than an ice bath?

Not definitively. Head-to-head research shows similar benefits for recovery and pain relief. WBC is faster, more comfortable for many people, and treats the whole body uniformly. Ice baths are much cheaper and have a longer evidence history. Choose based on preference, access, and budget.

What should I wear in the cryotherapy chamber?

Minimal clothing: underwear or shorts, sports bra (for women), socks, slippers or clogs provided by the facility, and gloves. Skin must be completely dry. Remove all jewelry and metal. Some facilities provide additional ear protection.

Can cryotherapy help with anxiety or depression?

Preliminary evidence is promising for mood improvement, likely through norepinephrine and endorphin pathways. WBC should not replace evidence-based treatments for clinical anxiety or depression (therapy, medication), but it may serve as a helpful adjunct for some people.

Is WBC FDA-approved?

No. The FDA has not approved or cleared any WBC device for any medical condition. It is marketed as a wellness service, not a medical treatment. In 2016, the FDA issued a consumer alert noting that WBC devices lack evidence of safety and effectiveness for medical conditions.

How quickly do you feel effects?

The mood and alertness boost is typically immediate, noticeable within minutes of exiting the chamber. Pain relief may last several hours to a day. Recovery benefits for muscle soreness are usually noticed the following day. Cumulative benefits (if they occur) build over multiple sessions.
