I will be honest with you: when I first tried whole body cryotherapy, standing in a chamber at -110 C for three minutes, I had one thought on repeat: "Why am I paying for this?" Then the session ended, and I felt genuinely good. Alert, energized, oddly happy. The question I have been asking since, as a chemist who wants evidence before enthusiasm, is whether that feeling represents a real physiological response or just the relief of no longer being frozen.
This guide is my attempt to answer that question with published research. I cover the mechanism, the types of cryotherapy available, what the evidence supports (and what it does not), the costs, the safety profile, and how to find a legitimate provider near you.
What Is Cryotherapy?
Cryotherapy literally means "cold therapy." In the wellness context, it refers to brief, controlled exposure to extremely cold temperatures for therapeutic purposes. The most common form is whole body cryotherapy (WBC), where you stand in a chamber cooled to -100 C to -140 C for 2 to 4 minutes. Localized cryotherapy applies cold to specific body areas using targeted devices.
The concept is not new. Hippocrates recommended cold therapy for pain and swelling over 2,400 years ago. Modern WBC was developed in 1978 by Japanese rheumatologist Toshima Yamaguchi for treating rheumatoid arthritis. It spread to Europe in the 1980s, where Polish and German researchers studied it extensively for inflammatory conditions, and reached the United States wellness market in the 2010s.
The physiological mechanism involves cold-induced vasoconstriction followed by rewarming vasodilation. When your skin temperature drops rapidly, your peripheral blood vessels constrict, shunting blood toward your core. Your sympathetic nervous system activates, releasing norepinephrine, endorphins, and anti-inflammatory cytokines. When you exit the chamber and rewarm, vasodilation increases blood flow to peripheral tissues, delivering oxygen and nutrients while flushing metabolic waste products. A 2017 review in the European Journal of Applied Physiology confirmed that WBC triggers significant increases in plasma norepinephrine (2 to 3 fold) and modulates circulating cytokine profiles (PMID: 27957622).
Types of Cryotherapy
Not all cryotherapy is the same, and the differences matter for both safety and effectiveness.
| Type | Temperature | Duration | Coverage | Cost | Key Differences |
|---|---|---|---|---|---|
| Whole Body (nitrogen) | -110 to -140 C | 2-3 min | Body (head exposed) | $40-$100 | Open-top cryosauna; nitrogen vapor cools air |
| Whole Body (electric) | -85 to -120 C | 3-4 min | Full body including head | $50-$100 | Walk-in chamber; electric refrigeration; no nitrogen |
| Localized | -20 to -40 C | 5-15 min | Targeted area | $30-$50 | Handheld device or targeted unit |
| Cryo Facial | -10 to -30 C | 10-15 min | Face and neck | $40-$75 | Pressurized cold air on face |
| Ice Bath / Cold Plunge | 2-10 C | 5-15 min | Full body immersion | $15-$40 | Water immersion; slower cooling; different mechanism |
Nitrogen vs Electric Chambers
This distinction is more important than most studios will tell you. Nitrogen cryosaunas are open-top units where liquid nitrogen evaporates to cool the air around your body. Your head stays above the chamber. They are cheaper to operate but have a critical safety limitation: liquid nitrogen displaces oxygen. In poorly ventilated rooms, nitrogen cryosaunas can create dangerous oxygen-depleted environments. The FDA has investigated deaths and injuries related to nitrogen cryotherapy, including a 2015 incident where a spa employee died inside a nitrogen cryosauna.
Electric cryotherapy chambers use compressor-based refrigeration to cool a walk-in room. No nitrogen is involved, so there is no risk of oxygen displacement. You walk into the chamber fully (including your head), and the temperature is more uniform. The clinical research from Europe, where WBC has been studied the longest, primarily uses electric walk-in chambers.
If safety is your priority, electric chambers have a better risk profile. If you use a nitrogen cryosauna, verify that the studio has proper ventilation, oxygen monitoring, and trained staff who never leave clients unattended.
Cryotherapy Benefits: What the Research Shows
Exercise Recovery
This is the most popular reason people try cryotherapy, and the evidence is reasonably supportive. A 2017 systematic review and meta-analysis examined 16 studies on WBC for exercise recovery and found that WBC significantly reduced muscle soreness (DOMS) compared to passive recovery, particularly at 24 and 72 hours post-exercise (PMID: 28144836). The effect sizes were moderate, comparable to cold water immersion.
A randomized crossover trial in elite rugby players found that WBC (3 minutes at -110 C) reduced markers of muscle damage (creatine kinase) and subjective muscle soreness compared to passive recovery, though the differences were modest (PMID: 27957622). The practical takeaway: WBC appears to speed recovery from intense exercise, but the margin of benefit over simply resting or taking a cold shower is not enormous.
Pain and Inflammation
The original clinical application of WBC was rheumatic disease, and this remains one of the better-supported uses. A pilot study of 120 patients with rheumatoid arthritis, fibromyalgia, and ankylosing spondylitis found that WBC at -105 C significantly reduced pain scores both acutely (lasting about 90 minutes post-session) and cumulatively over a 4-week treatment course (PMID: 10832164). The authors concluded that the short-term pain reduction facilitated more intensive physical therapy participation.
For chronic low back pain, a 2020 randomized trial comparing WBC plus exercise versus exercise alone found that the WBC group showed greater improvements in pain, disability, and quality of life (PMID: 32053768). The combination approach is key here: WBC as a standalone pain treatment is less convincing than WBC as an adjunct that enables more effective rehabilitation.
Mood and Mental Health
This is where things get interesting. Multiple studies have documented significant mood improvements following WBC, likely mediated by the norepinephrine and endorphin release triggered by cold stress. A 2008 study found that a course of 15 WBC sessions significantly reduced anxiety and depression scores in patients with mood and anxiety disorders (PMID: 18549865). Participants reported improved wellbeing, sleep quality, and energy levels.
A Polish study of healthy volunteers found that 10 sessions of WBC over 2 weeks produced significant improvements in mood, vitality, and cognitive function compared to controls (PMID: 24326680). The norepinephrine response to extreme cold is the most likely mechanism. Norepinephrine is both a neurotransmitter (affecting attention, focus, and mood) and a hormone (increasing heart rate and blood flow). A single WBC session can increase circulating norepinephrine by 200 to 300%.
My take: the mood-boosting effect of cryotherapy feels real and is biologically plausible. Whether it is clinically useful for treating diagnosed depression or anxiety disorders requires more rigorous study, but as a complementary practice for general mood and energy, the data is genuinely encouraging.
Skin Conditions
Localized cryotherapy has established uses in dermatology for treating warts, actinic keratoses, and some skin cancers (cryosurgery). Whole body cryotherapy for cosmetic skin benefits (tighter skin, reduced cellulite, "glow") has very little published evidence. Cryo facials are popular but the clinical data supporting them for anti-aging is essentially nonexistent. If you enjoy the experience, that is fine, but adjust your expectations for skin outcomes accordingly.
Weight Loss
Some cryotherapy studios claim you can burn 500 to 800 calories per session. This is misleading. Yes, your body expends energy to maintain core temperature during cold exposure, but the actual caloric expenditure during a 3-minute WBC session is modest, estimated at 50 to 80 calories above baseline. The metabolic increase persists for some time after the session as your body rewarms, but total extra burn is likely in the range of 100 to 200 calories, not 500 to 800. Do not choose cryotherapy as a weight loss strategy.
Cryotherapy Risks and Side Effects
Cryotherapy is generally safe when administered properly, but it is not risk-free:
Common Side Effects
- Skin redness and tingling: Normal and temporary. Resolves within 10 to 20 minutes.
- Numbness in extremities: Expected during the session. If it persists for more than 30 minutes after, report it to the staff.
- Lightheadedness: Caused by the sympathetic nervous system response. Usually brief.
- Headache: Occasionally reported, especially with electric chambers where the head is exposed to cold.
Serious Risks
- Frostbite: Can occur if sessions exceed recommended duration or if skin is wet/damp entering the chamber. Always dry off completely before a session and remove all jewelry.
- Oxygen depletion (nitrogen chambers only): In poorly ventilated rooms, nitrogen gas can displace oxygen and create a suffocation hazard. The 2015 spa worker death was attributed to oxygen depletion. Electric chambers eliminate this risk entirely.
- Cold-induced urticaria: Some people develop hives or allergic-type reactions to extreme cold. If you have a history of cold urticaria, avoid WBC.
- Cardiac events: Extreme cold causes a spike in blood pressure and heart rate. People with uncontrolled hypertension, recent heart attack, or severe cardiovascular disease should not use WBC without medical clearance.
Contraindications
- Uncontrolled high blood pressure
- Recent heart attack or unstable angina
- Raynaud's disease (severe)
- Cold urticaria or cold allergy
- Peripheral vascular disease
- Deep vein thrombosis
- Pregnancy
- Open wounds or active skin infections
- Seizure disorders
How Much Does Cryotherapy Cost?
Here are real prices from studios in our BestDosage directory:

| Cold Plunge (studio) | $15-$40 | $75-$200 | $79-$149 |
Most studios offer a first-session discount ($25 to $40) or an introductory package. If you plan to go regularly (2 to 3 times per week), an unlimited membership typically saves 50 to 70% compared to per-session pricing.
Insurance does not cover cryotherapy. Medicare classifies it as experimental. Use our Treatment Cost Calculator to estimate your monthly spend and compare with other modalities.
How Often Should You Do Cryotherapy?
The clinical protocols provide a useful framework:
- Exercise recovery: Within 1 to 2 hours post-workout. Most athletes use it 2 to 4 times per week during heavy training blocks.
- Pain and inflammation: Daily or every other day for 2 to 4 weeks (the rheumatoid arthritis studies used this frequency), then 2 to 3 times per week for maintenance.
- Mood and wellbeing: 2 to 3 times per week showed significant mood improvements in the published studies.
- General wellness: 1 to 3 times per week is the most common recommendation from experienced providers.
Start with 2 sessions per week and see how you respond before increasing frequency. More is not necessarily better, and your body needs time to adapt to the cold stress.
How to Choose a Cryotherapy Center
Here is what I evaluate when scoring cryotherapy studios for BestDosage:
- Chamber type: Electric chambers are safer than nitrogen. If they use nitrogen, verify ventilation systems, oxygen monitors, and staff training.
- Staff training: Operators should be trained on emergency procedures, timing protocols, and contraindication screening. Ask about their training program.
- Intake screening: Before your first session, you should be asked about cardiovascular conditions, Raynaud's, cold allergies, pregnancy, and medications. No screening = red flag.
- Temperature verification: The chamber should display the actual temperature. Ask if they calibrate their equipment regularly.
- Emergency protocols: The studio should have procedures for cold injury, fainting, and allergic reactions. Staff should never leave you alone during a session.
- Clean, professional environment: Dry floors (wet floors + extreme cold = injury risk), clean towels, proper changing areas.

Frequently Asked Questions About Cryotherapy
Is cryotherapy better than an ice bath?
Different mechanisms, different experiences. Ice baths use water immersion at 2 to 10 C, which conducts heat away from your body much more efficiently than cold air. A 10-minute ice bath and a 3-minute WBC session produce comparable reductions in skin and muscle temperature. Ice baths are cheaper and have a longer research history (especially for athletic recovery). WBC is faster and more tolerable for most people. Neither is definitively "better." Choose based on your preference, access, and budget.
Can cryotherapy help with sleep?
Some users report improved sleep after cryotherapy sessions, likely related to the norepinephrine and endorphin response, post-session relaxation, and mild fatigue from the cold stress. There are no published RCTs specifically studying cryotherapy for sleep quality, but the mechanism is plausible. If you try it for sleep, schedule sessions in the late afternoon or early evening rather than right before bed, as the initial sympathetic activation can be stimulating.
What should I wear in a cryotherapy chamber?
Minimal clothing: shorts or underwear, sports bra for women, and the protective gear the studio provides (gloves, socks, slippers, ear band, face mask for electric chambers). Skin should be completely dry. Remove all jewelry, piercings, and wet clothing. Some studios provide robes for walking to and from the chamber.
How quickly will I feel results from cryotherapy?
Most people feel an immediate mood lift and energy boost after their first session, likely from the norepinephrine release. Pain and inflammation benefits typically require a series of sessions (5 to 10) before noticeable improvement. Recovery benefits for athletes are generally felt within hours of the session. Do not expect dramatic results from a single visit.
Can I do cryotherapy every day?
Daily cryotherapy is generally safe for healthy adults and was used in several clinical studies. The rheumatoid arthritis protocols used daily sessions for 4 weeks. However, for general wellness, 3 to 4 sessions per week is usually sufficient. Daily use increases cost without clear evidence of additional benefit for most people.
The Bottom Line
Cryotherapy has a real evidence base for exercise recovery, pain management in inflammatory conditions, and mood improvement. The strongest data supports it as a complementary treatment, enhancing the effectiveness of physical therapy, exercise programs, and rehabilitation protocols, rather than as a standalone therapy.
The safety profile is good when administered properly, but the type of chamber matters. Electric chambers eliminate the nitrogen-related risks that have caused the most serious incidents. Verify your studio's equipment, training, and screening procedures before your first session.
At $40 to $100 per session, cryotherapy is a moderate investment. If recovery, pain management, or mood support are your goals, a trial of 5 to 10 sessions will give you a solid sense of whether it works for you. Just keep your expectations grounded in what the research actually shows, not what the marketing promises.
