The distinction between traditional cold therapy and instant localized cryotherapy is significant, particularly in how each method cools the body. Traditional methods like cold water, ice packs, or baths rely on “progressive cooling.” In this scenario, ice immediately begins to warm up as it interacts with ambient air. It also warms up as soon as it’s applied to an inflamed area, where there is heat and the horse’s skin temperature is higher than normal. The warming of ice by air or body heat causes ice to melt fairly quickly, only offering the most effective cooling within the first 5 to 7 minutes. Next, as the ice melts, the body‘s heat becomes trapped, especially when using boots, potentially leading to necrosis. The process is also time–consuming, cumbersome, and can cause discomfort or agitation in horses.
In contrast, instant localized cryotherapy operates at -108ºF with 52 bar (754 psi) of pressure, offering a much faster approach. This “thermal shock” message reduces the skin’s surface temperature to 39ºF which is the optimal temperature needed to immediately initiate several physiological processes necessary for healing; analgesic, anti–inflammatory, vasomotor, myorelaxant, and lymphatic. As a result, the use of instant localized cryotherapy enforces a reduction in pain, decreases swelling and edema, increases the delivery of oxygen, collagen, and proteins essential for healing as blood vessels expand four times in size, improves range of motion, and expels waste and toxins accumulated in the tissue. Additionally, unlike traditional methods, instant cryotherapy avoids the issues of moisture, gradual warming, and trapped heat. This rapid, controlled cooling provides a more effective, efficient, and safer treatment, making it a superior option in various therapeutic contexts.
