Acute injuries and surgery are painful and often prevent us from leading a normal life for weeks or even months. Localised cryotherapy minimises bruising and helps to speed up recovery time significantly. The extreme cold temperature isolates and reduces blood flow to the injured area, which helps to reduce swelling. Tissue damage is decreased by initially reducing metabolic rate, thus lessening the tissues’ need for oxygen and limiting secondary tissue injury caused by compromised circulation. The blood is infused with nutrients and enzymes, while the release of endorphins reduce pain perception.
