Freezing frenzy: Cryotherapy makes big promises despite dearth of evidence – Calgary

When torn knee cartilage threatened a Calgary man’s career as a professional Brazilian Jiu Jitsu fighter, he kept his cool, stripped down to his underwear and climbed into a metal canister chilled to -145 C.

Tim Blanchard exposed his nearly naked body to temperatures lower than anything recorded in the natural world, in a controversial but increasingly popular treatment known as cryotherapy.

Unlike traditional ice-bath treatments, cryotherapy doesn’t require long, uncomfortable stints in frigid water. Advocates claim three minutes in a cryochamber is all that’s needed to enjoy the same benefits, including reduced inflammation.   

“A person that really brought it to the forefront was [retired basketball player] Kobe Bryant, back when he was playing. When it comes to that level of athlete, they know what’s working and what’s not because they’re so in tune with their body,” said Jaipaul Dhaliwal, owner of N2 Cryotherapy in northeast Calgary, one of two cryotherapy providers in the city.
