Using ice or cold water to relieve soreness and reduce swelling has a long history. More recently, cold shock therapies such as whole body cryotherapy and cold water immersion have emerged as treatments to alleviate chronic pain, combat inflammation, and promote faster muscle recovery. Whole body cryotherapy exposes the body to extremely cold temperatures (-140 to -160 degrees Celsius) by circulating concentrated nitrogen gas within a cryosauna for 1 to 3 minutes. This invigorating and non-toxic treatment has been used for decades throughout Europe and in Japan by people looking to manage pain, reduce inflammation, and recover faster.
