The Real Science Behind Cold Exposure: What Huberman Wants You to Know

Short answer: Whole-body cryotherapy is a brief, supervised exposure to very cold, dry air in a specialist chamber. Sessions usually last only a few minutes. People commonly use it as part of a recovery or wellness routine, but individual responses vary and it is not a cure or a substitute for medical treatment.

At LondonCryo, whole-body cryotherapy takes place at our St John’s Wood clinic after a suitability check. If you already know you want to try it, view our whole-body cryotherapy options and current prices.

What is whole-body cryotherapy?

Whole-body cryotherapy exposes most of the body to extremely cold, dry air for a short, controlled period. It differs from applying ice to one area and from sitting in cold water. Clients wear protective items supplied or specified by the clinic and remain able to communicate with the team throughout the session.

Why do people book cryotherapy?

Recovery routines

Some clients use brief cold exposure around demanding training or busy schedules.

Cold exposure

It offers a short, dry alternative for people who dislike immersion in an ice bath.

Wellbeing

Clients often describe the experience as invigorating, although responses are personal.

What does the evidence say?

Research into whole-body cryotherapy is still developing. Some studies explore exercise recovery, soreness and perceived wellbeing, but findings and protocols vary. It should therefore be presented as an optional recovery or wellness treatment—not as a proven way to burn fat, treat disease, “boost immunity” or guarantee a particular result.

Cryotherapy versus an ice bath

Both involve cold exposure, but the experience is different. Cryotherapy uses cold, dry air for a very brief period, while an ice bath uses cold water and generally lasts longer. Water transfers heat differently from air, so temperatures and session times should not be compared directly.

What happens during a first session?

1. Screening: the LondonCryo team checks relevant health information and explains the experience.
2. Preparation: you change into the required clothing and protective items.
3. Brief session: you enter the chamber and remain in contact with the team throughout.
4. Warm up: after leaving, you dress and allow your body to return comfortably to its normal temperature.

Safety first: Cryotherapy is not suitable for everyone. Disclose pregnancy, uncontrolled high blood pressure, cardiovascular or circulatory conditions, cold-related disorders, reduced sensation, recent illness and any other relevant medical history. If you are unsure, seek advice from your healthcare professional before booking.

When should athletes use cold exposure?

The best timing depends on the training goal. Some athletes choose cold after competition or demanding endurance work. Those prioritising strength or muscle growth may prefer not to use intense cold immediately after every resistance session. Ask your coach or clinician for advice tailored to your programme.

Frequently asked questions

How long does whole-body cryotherapy take?

The cold exposure normally lasts only a few minutes, with additional time needed for screening, changing and preparation.

Is whole-body cryotherapy the same as an ice bath?

No. Cryotherapy uses cold, dry air; an ice bath uses cold water. The temperature, heat transfer and experience differ.

Does cryotherapy burn fat?

Cryotherapy should not be sold as a weight-loss or fat-removal treatment. Choose a consultation-led body-contouring pathway if that is your goal.

How much is a first session?

LondonCryo’s current first-time whole-body cryotherapy session is £59. Confirm the current price and suitability when booking.
