This cryotherapy involves rapid cooling of the whole body at extremely low temperatures
(cryogenic, below -100°C) to trigger physiological responses to cold. Such cryotherapy is
performed in a cryogenic chamber, ensuring appropriate treatment conditions - temperature
and humidity. While in the chamber, the patient must have regular contact with the
physiotherapist, usually through glass doors and speakers. A special alarm device allows the
patient to call for help in an emergency, and the door can be easily opened by the person
inside. The inside of the chamber is lined with a material that does not absorb moisture. The
walls do not have any sharp protruding metal parts to avoid contact with the patient, or to
cause very unpleasant feelings [Biały et al. 1998; Adamowicz 2005; Brojek & Warzocha 2006].
