Cryotherapy Studies

Clinical studies conducted worldwide have examined the physical effects of whole body cryotherapy (WBC). The following summarizes the results of several of these studies.

Physical Performance

A single exposure to WBC significantly decreases inflammation after strenuous exercise and may accelerate recovery and reduce exercise induced muscle damage.

WBC caused a decrease in pro-inflammatory (bad) interleukins (ILs) and rise in anti-inflammatory (good) ILs. By contrast, ice application has been shown to increase proinflammatory ILs by as much as 29% (Reference 8 in article). In any case, whether blood flow is shunted away from muscles is slowed and physiologically results in less muscle damage and faster recovery. (Reference 49 in article).

Norepinephrine is the only hormone that responded positively to WBC (3x/wk) and may play a role in pain relief effect. (Reference 60 in article).

No effect on aerobic or anaerobic capacity.

Medical Conditions

A study of rheumatoid arthritis patients reported the one variable that showed definite improvement with WBC (vs local cold treatment) was pain. Patients report less pain following WBC.

Effects of whole body cryotherapy on multiple sclerosis patients was positive (and postulated to be) beneficial. The total antioxidative state is distinctly reduced in MS patients vs. healthy population. The WBCT proved beneficial in treatment of MS patients and better than exercise alone.

“WBC is used widely in many applications, especially degenerative and inflammatory joint diseases and fibromyalgia.” (Reference 2 Sieron A, Cieslar G. The application of cold in medicine – cryosurgery and cryotherapy. Bielsko-Biala Poland:a-Meica Press; 2003).

Study of a small sample suggests positive effects on treatment of depressive and anxiety disorders. It is postulated/suspected that the pain relief associated with WBC and that commonly accompany emotional disorders may be responsible for the perceived benefits.

Lung and Cardiac Function

Blood Pressure is not affected with acute or long-term WBC.

(The blood pressure response to an acute and long-term whole-body cryotherapy (-110C) in men and women. Tmja Westerlund, Juhani Smolander, Arja Uusitalo-Koskinen, Marja Mikkelsson. Journal of Thermal Biology 2004; 29:285-290.

WBC has no effect/does not impair cardiac function).

WBC has no demonstrated or reported adverse effects on lung function in normal individuals and only minimal effect on asthmatics. When they occur, those mild effects reverse quickly after treatment. There are no reports of need to terminate treatment due to interference with lung function.

If concerned about potential adverse effects a simple paper face mask can be worn during treatment. Lung function after repeated WBC treatment: several pressure studies have demonstrated pain relief from fibromyalgia and arthritis (Metzger 2000) as well improved lung function (Yamauchi 1988). This study focused on lung function and showed a mild bronchoconstriction effect as opposed to bronchodilatory effect reported by Yamauchi. This effect was "minor" after 30 minutes total WBC time.

Asthmatics exposed to WBC had minor bronchoconstriction and had full recovery in 30 minutes to 2 hours duration. Use of a thin paper mask may be protective against facial cold exposure. These patients were in an enclosure higher than head level. Impact Cryotherapy does not cover the head or mouth and therefore any effect would be much less likely.

No significant effect on forced expiratory volume.
