Whole-body cryotherapy exposes the body to extreme cold, typically between minus 110 and minus 140 degrees Celsius, for two to three minutes in a purpose-built chamber. The immediate response is strong: blood vessels in the skin constrict to preserve core temperature, heart rate and blood pressure change, and the body releases stress hormones such as noradrenaline. Many people feel alert afterwards.
The evidence for recovery benefits is limited. A Cochrane review (Costello JT et al., 2015) found only four small trials, 64 participants in total, almost all young men. It concluded that there was insufficient evidence to determine whether whole-body cryotherapy reduces muscle soreness or improves subjective recovery after exercise, and noted that adverse effects had not been properly monitored. Laboratory studies of inflammatory markers exist, but they do not settle the question of clinical benefit.
Cold exposure also affects how people feel. Noradrenaline rises with cold, and many people report better mood and alertness after a session, but this has not been well tested against a control. Compared with ice baths, cryotherapy delivers cold through dry air rather than water, which some people find easier to tolerate. Neither approach is risk-free for people with heart or circulation problems.
A session at our clinic takes about three minutes of cold exposure, after preparation and a safety briefing. You wear minimal clothing with socks, gloves and ear protection to protect the extremities. The experience is intense but brief. There is no downtime, and you can resume normal activity straight away.
We offer cryotherapy for people who enjoy cold exposure and want it supervised, and we are clear that the recovery evidence is weak. Book a consultation with our longevity physician to discuss whether it suits you.
