Cold exposure is now sold commercially in several quite different forms, and they are routinely discussed as though they were the same thing. They are not — they differ in temperature, duration, mechanism and risk profile, and the evidence behind them differs too.
This is a companion to our guide on cold water immersion at home. Here the focus is on commercial and clinical settings: what is actually on offer, how the formats differ, and what to check before handing over money.
The Formats, and Why the Differences Matter
Cold water immersion. A tub or plunge pool, typically 5 to 15°C, for a few minutes. This is the format with the most research behind it, particularly for recovery from training. When studies refer to cold water immersion, this is generally what they mean.
Whole-body cryotherapy. A chamber cooled with nitrogen vapour or refrigerated air to extreme temperatures — often quoted around minus 110 to minus 140°C — for two to three minutes. It feels dramatic and markets well. The important physiological point is that air, even very cold air, transfers heat far less efficiently than water. A brief exposure to extremely cold air does not cool tissue the way a few minutes in cold water does. Evidence gathered on water immersion should not be assumed to apply.
Localised cryotherapy. A targeted device applied to a specific area. Used in some clinical settings; a different proposition again from whole-body exposure.
Contrast facilities. Sauna paired with plunge pool, increasingly common in recovery studios. Covered in our contrast therapy guide.
The commercial claim that these are interchangeable routes to the same benefits is not supported. If a facility’s marketing cites immersion research while selling chamber cryotherapy, that is worth noticing.
What to Check Before You Book
Water temperature is measured and displayed. For immersion, an actual thermometer, actually visible. “Ice cold” is not a specification.
Water hygiene, and this is the big one. A shared plunge pool is a shared body of cold water that many people have sat in. Ask directly: how is it filtered, how is it sanitised, how often is it fully drained and refilled, and is the sanitiser level tested and logged? A facility that cannot answer clearly is not one to use. Cold water does not prevent bacterial growth — it slows some organisms and does nothing to others.
Supervision. Someone trained, present, and actually watching. Given the gasp reflex and the cardiac load, unsupervised commercial cold immersion is a poor idea however experienced you are.
A screening process. A facility that takes no history from you before your first session has no way of knowing whether you have a cardiac condition. That is a bad sign about everything else too.
Clear time limits, enforced. Not left to the customer’s judgement.
A sensible rewarming space. Somewhere warm, with time built in. After-drop is real: core temperature can keep falling after you get out.
Questions Worth Asking a Cryotherapy Operator
- What temperature does the chamber actually reach, and how is it verified?
- Is the operator trained, and in what?
- What is the emergency procedure, and has it been rehearsed?
- For nitrogen systems: how is oxygen level in the room monitored?
That last one matters. Nitrogen vapour displaces oxygen. Reputable operators monitor for it and will tell you how without hesitating.
Clinical Versus Commercial
Cold is used in clinical practice — in physiotherapy and sports medicine — generally as one element of a plan, applied by someone who has assessed the person in front of them.
The difference from a commercial studio is assessment. A clinician takes a history, has a defined purpose, and adjusts. A studio sells sessions. Both can be legitimate; they are not equivalent, and the clinical route is the appropriate one if you have an injury or a health condition.
Nothing in this article is guidance on using cold exposure to manage a medical condition. That conversation belongs with a qualified practitioner.
The Recovery Timing Question
One point worth carrying into any commercial setting, because staff will rarely raise it.
Cold immersion after training reduces perceived soreness. It may also blunt some of the adaptive response that strength and muscle growth depend on. If you are training for strength or size, routinely plunging straight after every session may work against your goal.
The reasonable approach: use it when rapid recovery matters more than adaptation — competition, tournaments, heavy fixture congestion — and be more sparing during dedicated strength blocks. If a facility tells you more is always better, they are selling sessions rather than advising you.
Cost and Commitment
Commercial cold exposure is typically sold as memberships or session packs, and often at premium prices for cryotherapy in particular.
Before committing, consider that the cheapest effective version of this practice is a cold shower in your own bathroom, and the second cheapest is a bath with ice in it. Those are the formats most of the research actually used. Paying substantially more for a colder, briefer, less-evidenced format is a choice worth making deliberately.
Safety, in Any Setting
- Never submerge your head. The gasp reflex is involuntary.
- Never use a facility that leaves you unsupervised.
- Disclose your health history honestly at screening.
- No alcohol beforehand.
- Get out at the first sign of dizziness, confusion or uncontrollable shivering.
- Rewarm gradually. Do not drive immediately afterwards.
Speak to a doctor before starting if you have any cardiovascular disease, arrhythmia or uncontrolled high blood pressure, Raynaud’s syndrome or severe cold sensitivity, diabetes with impaired sensation, epilepsy or any condition involving loss of consciousness, or if you are pregnant.
The Practical Summary
Commercial cold exposure ranges from well-run and genuinely useful to expensive theatre with questionable hygiene. The variables that matter are measurable: water temperature, sanitation practice, supervision, screening and emergency preparedness.
Ask the questions. A good operator will welcome them.
