HERE`S WHY
The liquid nitrogen and subsequent cool body temperature trick the brain into producing increased quantities of nutrients like collagen, oxygen, and erythrocytes, or red blood cells. Then, even as the body warms back to a higher temperature, the nutrient boost continues to take effect. The blood will carry them throughout the body, leading to benefits like improved healing, increased blood flow, and firmer, plumper skin. The process also eases inflammation and pain from injury, which is why it’s attractive to athletes. Think of cryotherapy as an ice pack, except a much more powerful one. Applying the cool temperature numbs the area, which aids in relief and sends an influx of immune-boosting cells and nutrients to the area.
