What's cool (well, actually quite cold) is that you only spend a maximum of 180 seconds in the cryotherapy chamber. As Whole Body Cryotherapy, your entire body is in the chamber, yet your head remains outside the unit. Once inside our innovatively designed octagon chamber, you'll experience subzero temperatures created by nitrogen-chilled air, with chamber levels dropping to a range of -130 to -190 degrees Fahrenheit. Nitrogen is being introduced at -301 degrees negative Fahrenheit, but is being controlled to tolerable and safe levels. So, what actually happens? The extreme cold you're exposed to triggers the skin's sensors, which activate a response from your central nervous system. In actuality, the body “thinks” it is freezing and goes into survival mode, delivering blood to the core to protect your vital organs. There, your blood collects oxygen and nutrients, and when you step out of the chamber this oxygen rich blood flow back through the body and your extremities, flushing out toxins and boosting circulation. This is truly rejuvenation happening at the body's cellular level.
