The principle behind cryotherapy is rooted in the body’s natural response to extreme cold. When exposed to such low temperatures, the body’s survival instincts kick in, triggering a cascade of physiological reactions. Blood vessels constrict, redirecting blood flow from the extremities to vital organs. This process, known as vasoconstriction, is followed by rapid vasodilation upon exiting the chamber, flooding the body with nutrient-rich, oxygenated blood.

This sudden temperature change stimulates the release of anti-inflammatory molecules and endorphins, the body’s natural pain-killers. Additionally, the cold exposure activates the body’s “fight or flight” response, releasing norepinephrine, a hormone that can enhance focus and energy levels.

From Niche Treatment to Mainstream Recovery Tool

The journey of cryotherapy from obscure medical treatment to sports recovery staple is a testament to its perceived effectiveness. Originally developed in Japan in the 1970s to treat rheumatoid arthritis, cryotherapy quickly gained traction in Eastern Europe for its potential in sports medicine.

The turning point came in the early 2000s when professional sports teams, particularly in soccer and basketball, began incorporating cryotherapy into their recovery protocols. High-profile athletes like LeBron James and Cristiano Ronaldo publicly endorsed the treatment, catapulting it into the spotlight.

Today, cryotherapy chambers are a common sight in professional sports facilities, high-end gyms, and specialized recovery centers. The NFL’s Dallas Cowboys were among the first to install a cryotherapy chamber in their training facility, setting a trend that many teams across various sports have since followed.
