The Cryosauna uses nitrogen gas to lower your skin’s surface temperature by 30-50 degrees Fahrenheit over a period of 2-3 minutes. The skin reacts to the cold in 2 major ways:
1) Messages are sent to the brain from the nerves in the skin which then stimulate the regulatory functions of the body. This creates a positive neurological effect. 2) The skin exposure to the extreme temperatures triggers the release of anti-inflammatory molecules and endorphins (feel good chemicals).
Cryosaunas have been used for the past 30+ years without any severe adverse reactions ever recorded. Problems have only arisen if a client steps into the machine with wet clothing, especially wet socks, as water will freeze immediately at these temperatures. The nitrogen being used to cool the single-person in the cryosauna is safe. Our operator will raise the platform you stand on so that your head is above the heavier nitrogen vapors so that you will breathe the room air. For added safety, our chamber is also equipped with an oxygen monitor at the level of the mouth, which will shut off the nitrogen supply should the oxygen concentration drop by 0.5%. In order to protect the more temperature sensitive tissues such as hands and feet, we will provide you with socks, slippers, and gloves.
A session is of short duration (2-3 minutes), and the cold is ‘dry’ so it is very tolerable. Towards the end of the session, you may get a ‘pins and needles’ sensation, which disappears immediately after you step out of the chamber.
During each session, the body releases endorphins, which are hormones that make you feel good and energetic. The mood-enhancing effects from each session can last for days. These endorphins are also what reduce pain and inflammation. The extreme contraction of the vessels in the skin can help to clear toxins from the body which also reduce inflammation and stimulate collagen to be produced, which rejuvenates and tighten the skin.
Depending on the condition of treatment, you should initially take 5 – 10 treatments in close succession (separated by 1-2 days — e.g. 3x/week) to maximize your results. After that, you can take fewer treatment spaced further apart to maintain and improve your results (e.g. once every week or two weeks).
The immediate cold impact of the cryosession will raise the internal body temperature for a short period of time. The stimulation of the immune system can help decrease the severity and frequency of future colds.
