Is whole body cryotherapy worth the hype?


Short answer, Not really. I’ll explain further.

Cryotherapy is a method of recovery which is done by lowering the skin temperature of the body. Some of the most common modalities are ice packs, ice massages, gels and cooling creams. Recently whole-body cryotherapy (WBC) chambers have been introduced to high level foot ball and rugby teams. But is this new, and costly, method really the best way to enhance recovery through cryotherapy?

I hit the research hard. One of the first studies I found from Hausswirth, el al (2011) claims the benefits of WBC on highly trained runners. One large flaw in this study is that the other modalities involved were far-infrared (not a highly reliable modality) and basically sitting in a chair for ten minutes. These two “sham” modalities would, of course, show that WBC is a reliable way to recover after running.  It’s studies like this that make me angry. They manipulate the data by introducing two modalities they know won’t work to “prove” that WBC is reliable.

Other research I won’t even mention here were studies paid for and sponsored by companies that make WBC chambers. I don’t give research like this the time of day. Many involve manipulated data to sell a product to teams that can afford it.

A more recent study by Viera, et al (2015) studied the effect of WBC on a vertical jump after high intensity training by placing participants in a chamber at the suggested -110 degrees for 3 minutes and a control temperature of 21 degrees for the same time. In this study there was no significant difference between the WBC and control group. Thus, suggesting that some of the “benefits” of WBC are possibly due to the placebo effect. 

One of the better studies from Holmes & Willoughby (2016) looked at previous studies and compared WBC to cold water immersion on recovery and skin temperature. One of the claims of WBC is that the extremely cold temperature is more effective at lowering the skin temperature than other modalities. In this study participants used a WBC chamber at -110 to -120 degrees for 2-4 minutes and cold-water immersion at 8-14 degrees for 5-10 minutes. The results showed that using cold water immersion lowers the skin, muscle and core temperature more effectively than WBC. The study suggests that further high-level studies on WBC be performed to confirm their claims.

My personal opinion is that WBC is very expensive and some of the membership rates are well over £100 a month. Most people would not use the WBC more than once or twice a week, making it a very expensive means of recovery. Plus, it means coming home from your run or workout, getting in the car, driving to a centre, going in a chamber for 3 whole minutes then driving back home. A lot of effort when you can simply fill your tub with cool water once you get home and sit and chill in it. Studies are not conclusive of its claims, and with that kind of cost, you may be better off buying a gym membership or hiring a personal trainer.
However,  saying that, its definitely worth trying. I will admit though getting a snapshot of yourself in the mittens, slippers and headband in a chamber is pretty cool, but unless it works for you, it’s just a lot of money for cold air.
