Whole-body cryotherapy (WBC) is increasingly being studied and used in various populations, mainly focusing on improving the body’s regenerative capacity. More comprehensive summaries of anti-inflammatory responses are needed. To systemically assess the effect of WBC on the inflammatory response in humans based on randomized controlled trials (RCTs).

Cold has been used to treat illnesses since at least 450 BC when Hippocrates advised packing wounded soldiers in ice to delay death. In the 1800s, wounded soldiers were cooled to promote recovery by reducing pain and bleeding.

Nowadays, whole-body cryotherapy is a medical physical treatment widely used in sports medicine. Recovery from injuries (e.g., trauma, overuse) and after-season recovery are the main purposes for application. However, the most recent studies confirmed the anti-inflammatory, anti-analgesic, and anti-oxidant effects of this therapy by highlighting the underlying physiological responses.
