Whole Body Cooling (WBC)   Vs   Partial Body Cooling (PBC)

Walk-in Electric Cold Air Chamber versus Liquid Nitrogen Sauna

A study by Dr Hausswirth, et al, (France), 2013 has compared electric cooled air, walk-in chamber(s) to liquid nitrogen cooled saunas. Conclusions of the study are that WBC (Whole Body Cooling) is much more significant than PBC (Partial Body Cooling) in the activation of the autonomic nervous system (ANS), the system responsible for nerve function and cellular activation. Thermograms below show the measured skin temperature differences from a walk – in chamber (Group A) (-166F) to a cryo sauna (group B) (-256F). Outcomes prove that treatment effect is a direct result of uniform skin temperature reductions. WBC was statistically and significantly better in activation of the ANS and as measured by modulation markers in the blood (epinephrine, norepinephrine, and dopamine). Temperature comparisons of the systems are irrelevant. Skin temperature reductions during treatment exposure (measured in the neck, chest, and quadriceps regions) are the markers of treatment benefit.

Examples of thermograms obtained immediately before (a,b) and after (c, d) a partial-body cryostimulation (PBC) session (Group B) and a whole-body cryostimulation (WBC) session (Group A).

Group A

Walk-in Chambers
WBC – Whole Body Cooling


Before and after thermograms (thermal imaging camera) show skin temperature drops from head-to-toe in a walk-in chamber produces greater therapeutic results (figures C&D)

Group B

Open Faced Nitrogen Sauna
PBC – PARTIAL Body Cooling

Forced air cooling, or use of liquid nitrogen, regardless of temperatures stated , are not considered Whole Body Cryotherapy. WBC benefits are related to whole body skin temperature drops during exposure!

The more complete cooling of the skin with WBC (stimulation of cutaneous receptors in the face, neck, chest, and lower body), the greater the constriction of local arterioles and venules. This decreases metabolic processes, thereby decreasing inflammatory responses and the formation of edema (swelling) around the injured tissues. WBC has also been shown to reduce cell necrosis, neutrophil migration, and nerve conduction velocity, which in turn reduces secondary tissue damage and pain sensation.
