Many people think that ice application simply involves applying something cold to an injured area, but it's actually a science.
Ice application, professionally known as "cryotherapy," uses low temperatures to rapidly cool the injured area, thereby achieving hemostasis, reducing swelling, relieving pain, and reducing inflammation.
It acts like a calm commander, quickly controlling the situation when the body experiences "chaos" (injury).
Vascular "constriction": Low temperature causes capillaries to constrict rapidly, like temporarily tightening a damaged water pipe, reducing bleeding and leakage.
Metabolic "speed bump": Low temperature lowers the metabolic rate of cells, reducing the "fueling" of inflammatory mediators and controlling inflammation at its source.
Nerve "sedative": Low temperature slows down nerve conduction speed and raises the pain threshold, allowing you to temporarily escape severe pain and gain "a moment of peace."
After a sports injury, ice application is your first choice
Whether it's a sprain on the sports field or a muscle strain in the gym, ice application is a crucial part of first aid.
Do you remember the RICE principle? Rest, Ice, Compression, and Elevation.
① Acute Phase (24-48 hours after injury)
Ice application is a key measure for controlling early postoperative joint swelling and pain.
It reduces continued bleeding in the surgical wound and joint cavity through vasoconstriction.
It inhibits tissue exudation, reducing joint effusion and surrounding soft tissue edema.
It provides significant postoperative pain relief, improving patient comfort. It reduces the incidence and severity of bruising around the joint after surgery.
② Rehabilitation Phase
After functional exercises that may cause microtrauma to the tissues (e.g., passive knee flexion training, use of a CPM machine, active range of motion exercises, or muscle strengthening exercises), ice application should be performed promptly. Each ice application should last 15 minutes to reduce muscle soreness and joint swelling.
