When treating an injury, there are a few things to consider when deciding whether to use heat or cold. Cold is typically used in the acute phase, or immediately after an injury. Cold therapy reduces superficial blood flow and helps prevent excessive swelling in the affected area. The numbing effect of cold therapy significantly decreases pain and muscle spasm. Heat, on the other hand, may be used in chronic injuries or shortly after the acute phase of an injury, usually when the swelling and inflammation have subsided and the tissue is no longer warm to the touch. Heat increases blood flow, which can help with tissue regeneration and repair, loosens muscles and joints, and provides an analgesic effect to soothe pain. When in doubt, use cold therapy to prevent the secondary complications of swelling and heat in the later stages of healing.
