It goes without saying that rapid cooling of the body's surface causes blood vessels to constrict as the body goes into protection mode, and then once out of the Whole Body CryoTherapy sauna the blood rushes back to heat up those areas. No doubt this action increases metabolism. Now then, with continued regular use of Whole Body CryoTherapy sauna sessions the body will strengthen its immune system and blood delivery system. This will elevate your body's long-term Basal Metabolic Rate (BMR).
Now then, why is an elevated BMR desirable? Well BMR is your base daily calorie burn before you do much of anything, just existing without workouts. If your base is 1500 calories, then you burn that amount automatically. If you increase your BMR you burn more calories each day. Certainly you will burn more calories warming your body up after a CryoTherapy sauna session, but that is just one day. What about the rest of the year?
If you can raise your BMR you will burn more calories, you can burn more calories by burning them more efficiently. Let's discuss that for a minute. Increasing your BMR means you burn fat quicker, your body heals itself faster, and you are more efficient with energy as you demand it from your body. Increasing your BMR isn't difficult; you can do it through a selective diet and high-intensity exercise, and / or get your system better at energy conversion and direct that energy where you need it quickly. The latter is where Whole Body CryoTherapy comes into play. It is interesting to note that a single 3-minute session of Whole Body CryoTherapy will burn as many calories during and after as a high-intensity anaerobic work out.
If you build more muscle in your body you will find it takes more calories to sustain it. You can build muscle through intense work outs. You can do harder workers with faster recovery times back-to-back when you use Whole Body CryoTherapy as part of your strategy. As your body replaces white fat with brown fat, it will take more energy to keep your body warm, thus you'll burn more calories in doing so. Suffice it to say there are many ways Whole Body CryoTherapy will increase your BMR.
An interesting paper to read on this is; “The Influence of whole body cryotherapy on the levels of some hormones in professional footballers,” by Ilona Korzonek-Szlacheta, Tomasz Wielkoszymski, Agata Stanek, Elzbieta Świętochowska, Jacek Karpe, Aleksander Sieron. Endokrynologia Polska 2007; 58 (1): 27-33.
The conclusion of this research notes: “Whole body cryotherapy leads to a significant decrease in serum T and E2, with no effect on LH and DHEAS levels. As a results of cryotherapy, the T / E2 ratio was significantly increased. The changes observed are probably due to cryotherapy-induced alternation in the blood supply to the skin and subcutaneous tissue, as well as to modulation of the activity of aromatase which is responsible for conversion of testosterone and androstendione to estrogens. ”
It's getting harder and harder to deny that Whole Body CryoTherapy is just a fitness fad, the results seem to speak for themselves, which is why entire professional sports teams are now using it.
