The difference between cold and hot compresses

Ice therapy and heat therapy differ significantly in treatment methods, effects, and applicable scenarios. Ice therapy typically involves the use of ice packs or cold towels. It works by constricting blood vessels, reducing congestion, and alleviating swelling. It is suitable for injuries, acute inflammatory phases, or bruising, helping to relieve pain and stop bleeding. Applying ice therapy immediately after an injury yields better results. When using ice therapy, avoid direct contact with the skin, limit each session to no more than 20 minutes, and allow at least a 1-hour interval between sessions to prevent frostbite. Heat therapy, on the other hand, uses hot water bottles or warm towels to dilate blood vessels and improve blood circulation, thereby relieving pain. It is effective for conditions such as diarrhea and muscle strain, and is particularly beneficial for promoting the resolution of bruising more than 48 hours after an injury. When applying heat therapy, carefully control the temperature to avoid burns, especially in individuals with reduced skin sensitivity. Choose the appropriate method based on your individual condition, monitor your response during treatment, and make necessary adjustments. If discomfort occurs, seek medical attention promptly.
