“…The temperature mentioned (setpoint temperature) often refers to the temperature of the air at the outlet or in the vicinity of the expansion device. Unlike in cryosaunas (partialbody cryotherapy), where studies have demonstrated significant differences between the actual temperature inside the cryocabin and the temperatures reported by manufacturers [15,16], no research has been conducted on this topic for whole-body cryotherapy. To answer the question regarding the agreement between the setpoint temperature and the actual temperature in the middle of the cryochamber in WBC, Figure 2 presents the time evolution of both these fields.…”

(1) Background: This article presents a study that aims to provide a precise understanding of the temperature distribution within a whole-body cryostimulation (WBC) chamber, whether it is empty or occupied by one or several individuals; (2) Methods: The study employs a mixed numerical and experimental approach, utilizing simplified computational fluid dynamics (CFD) simulations and experimental analysis; (3) Results: The results reveal a non-negligible temperature difference between the setpoint and actual temperature in the middle of the cryochamber. Furthermore, it is shown that the presence of individuals inside the chamber results in both an average temperature rise and a more heterogeneous thermal behavior associated with the number of individuals present. As the number of occupants in the cryochamber increases, the magnitude of the thermal gradient (up to 10 °C) and temperature heterogeneity (up to 13%) also increase; (4) Conclusions: The results suggest that when the cryotherapy chamber is occupied by three people, it becomes necessary to extend the duration of cold exposure to obtain a dose/effect ratio and analgesic threshold equivalent to those obtained when only one person is present. The findings of this study emphasize the need for further research to establish temperature guidelines and standardize measurement methods for effective WBC treatment.

(1) Background: This article presents a study that aims to provide a precise understanding of the temperature distribution within a Whole-Body Cryostimulation (WBC) chamber, whether it is empty or occupied by one or several individuals.; (2) Methods: The study employs a mixed numerical and experimental approach, utilizing simplified Computational Fluid Dynamics (CFD) simulations and an experimental analysis that employs thermocouples to determine the 3D thermal field in actual conditions.; (3) Results: The results reveal a non-negligible temperature difference between the setpoint and actual temperature in the middle of the cryochamber. Furthermore, it is shown that the presence of individuals inside the chamber results in both an average temperature rise and a more heterogeneous thermal behavior, which appear to be associated with the number of individuals present.; (4) Conclusions: The findings of this study emphasize the need for further research to establish temperature guidelines and standardize measurement methods for effective WBC treatment.
