Would you consider that exposing your physique temperatures of damaging 182 to 292 levels Fahrenheit is definitely extra gratifying than getting hit with a blast of freezing wind on an icy day? That’s what I discovered once I visited KryoLife, a New York Metropolis cryotherapy heart, on a wet winter day this March.
To check the frigid fad, I stood in a freezing chilly chamber for almost three minutes — clothed in solely my underwear, and the wool gloves, socks and clunky white clogs supplied to me. The icy temps are stated that will help you bounce again from exercises extra shortly and battle muscle and joint ache, amongst different claims.
“Muscle restoration is far sooner [after cryotherapy] due to elevated blood stream and diminished irritation,” says Joanna Fryben, CEO of KryoLife. Fryben first discovered of whole-body cryotherapy in her native Poland, when a physician really helpful it to her mom after knee substitute surgical procedure. Later, after shifting to the U.S. and changing into a private coach at Equinox, she realized that the advantages of whole-body cryotherapy may very well be helpful to a few of her shoppers, too.

The teeth-clatteringly chilly remedy, which has been used to alleviate joint ache and arthritis, cut back irritation, promote restoration and ship a rush of endorphins, appeared like a “no-brainer” for her consumer base, she says. Fryben opened KryoLife in 2014, providing remedies for $90 a session, and says enterprise has been so good they’re within the technique of opening a second location later this 12 months.
Getting into the Cryotherapy Chamber
Although suspicious of a few of cryotherapy’s claims (I’ve learn that it burns as much as 800 energy a session), I made a decision it was price battling the chilly. After signing a waiver (pregnant ladies, folks with cardiovascular issues, chilly allergy symptoms and hypertension ought to keep away from it), I used to be ushered right into a small, spa-like altering room.

“Whereas I felt refreshed after my one-time cryo remedy, the advantages of a practising cryotherapy long-term are nonetheless murky.”
Sweat is a no-no throughout cryotherapy — it may result in hypothermia! — so I used to be instructed to dry off my complete physique with a towel earlier than the remedy started. I used to be relieved to seek out that shoppers stand upright within the cryotherapy chamber. This allowed my head to poke out the highest so I may speak to the attendant controlling the machine. (To not point out, forestall the “Oh god, I’m locked in a freezer” panic assaults.)
No fan of the chilly, I braced myself for the 180 seconds of below-polar temps. Nonetheless, as soon as the liquid nitrogen-chilled air streamed into the chamber, I discovered that cryo-cold is definitely far more tolerable than the freezing blasts I’d be coping with all winter. The sensation was similar to experiencing dry warmth — the temperature is noticeable, however not as depressing as sticky humidity.
“The idea may be very easy: You go into the chamber, and it’s a struggle or flight response,” Fryben says. “You begin to breathe a lot sooner. It’s a little bit short-lasting stress on the physique.” My breath certainly grew extra fast, and after a minute or so I began feeling a tingling sensation in my limbs. Fryben assured me this was regular. It’s attributable to a launch of endorphins that happens all through your physique.

Simply as I used to be beginning to expertise an uncontrollable case of the shivers, my time was up and I hopped out of the chamber. Regardless of skipping my regular espresso that morning, I felt noticeably energized. My pores and skin was flushed and glowing, and I loved one thing akin to a “runner’s excessive” upon exiting the chamber.
The Science Behind Cryotherapy
Whereas I felt refreshed after my one-time cryo remedy, the advantages of a practising cryotherapy long-term are nonetheless murky. Cryo fans will typically bear remedies as typically as as soon as a day, to assist ease muscle restoration, or to battle situations like arthritis, says Mary Riley, LMT, ART, of Synergy Sports activities Remedy in Cleveland, Ohio. “We work with athletes, from weekend warriors all the way in which as much as professional, and we use it quite a bit for muscle restoration and serving to them to be on prime of their recreation,” she says. “We even have a pair rheumatoid arthritis shoppers who get nice profit from it, and are capable of transfer extra freely for the primary time in years.”

A assessment printed within the Journal of Sports activities Drugs in 2014 analyzed 10 whole-body cryotherapy research and located that whereas the remedy appeared to enhance subjective restoration and muscle soreness, there was, “little profit in the direction of useful restoration.” Whereas the examine didn’t determine any drawbacks to the remedy, they famous that icing, or ice baths, might supply comparable results, at much less price.
Riley notes that many think about cryotherapy a extra nice (and fewer time consuming) various to brutally chilly ice baths, which might typically last as long as 20 minutes. “Whenever you get out of an ice bathtub your muscle groups and tissues are chilly for hours,” Riley says. “Step out of cryotherapy and inside 10 minutes your physique is 100 % again to regular. You don’t danger harm from being so chilly and your physique can recuperate faster and get the precise some outcomes.”

But, each say that shoppers are sometimes hooked quickly after taking the plunge.
“Seeing what it does to folks, once I take heed to folks raving about it, to me that’s convincing sufficient,” Fryben says. “You see this of their faces, they’re [feeling] stronger.”
