Potential benefits of cryotherapy

Potential benefits of cryotherapy

Advocates for cryotherapy cite a variety of health benefits, many relying on claims of reduced inflammation. Scientific studies that demonstrate actual effectiveness are sparse as testing is still in the early stages and almost all benefits are currently theoretical.

Pain relief and muscle recovery are the primary reasons people try cryotherapy, since WBC could potentially be a quicker solution to problems solved by ice packs or ice baths. In 2000, a small study did show that WBC can provide short-term relief from pain caused by rheumatoid arthritis. A 2014 review of several studies determined that WBC has a small impact on pain relief and muscle recovery – with results comparable to cold-water immersion or local ice pack application.

It has been hypothesized that cryotherapy could prevent dementia by reducing inflammation associated with cognitive decline or impairment, but this theory requires more research and testing.

The same hypothesis of reduced inflammation has led to theories of WBC treating mental health conditions. A 2008 study of 60 outpatients found evidence that WBC could be a short-term treatment for depression and anxiety. WBC advocates with mental health conditions have claimed to feel a euphoria upon exiting a cryochamber, but there is not enough evidence to support long-term benefits or draw concrete conclusions.

Others believe WBC can support weight loss by using cold temperatures to force the body to work harder to stay warm. The theory is that the increased effort will boost metabolism, but a 2016 study found no significant evidence of body composition change after 10 sessions of WBC. There are more effective and safer ways to lose weight, including changing eating habits and exercising.

Cryotherapy facials conducted with a cryotherapy wand are increasing in popularity. While a formal study has not been conducted, proponents claim cryofacials can shrink pores, freeze off dead skin cells, rejuvenate skin and reduce redness.
