WHAT IS IT? No, this isn’t what happens when you end up sobbing after a tough gym sesh. Cryotherapy involves standing in a “chamber” (basically a freezer) where you’ll experience a few minutes of temperatures as icy as -90ºc. The therapeutic effect of freezing cold water is well known to spa therapists, but this A-list version costs up to £95 for three minutes at legendary London department store Harrods. HOW DOES IT WORK? The cold temperature produces a fight-or-flight response in the body, and users claim to feel glowing and re-energised as the shock of the cold sends oxygen coursing through their bod, speeding up their metabolism. It’s also claimed to help sore muscles and anti-ageing, which may be why cryotherapy is said to be addictive.
