Cryotherapy is completely safe. The Nitrogen used to cool the chamber is the same Nitrogen that makes up 78% of the air we breathe. The client’s head remains outside of the chamber for the entire session and they breathe regular room air. For added safety, the client also wears socks, gloves and boots (provided by Vita CryoStudio) throughout the session. A Vita CryoStudio certified employee will be with the client throughout the duration of the treatment.
