After prolonged periods of maintaining a fixed posture or engaging in high-intensity exercise, muscle fibers are prone to micro-tears and lactic acid buildup, leading to muscle stiffness and spasms. The low-temperature stimulation of cold compresses can reduce muscle metabolic rate and oxygen consumption, thereby relieving muscle tension and preventing delayed onset muscle soreness (DOMS). For patients with neck, shoulder, back, and leg pain, appropriate use of cold compresses can relax tense muscle groups, improve local blood circulation, and restore muscle elasticity. After the acute inflammatory phase, cold compresses are often used first in alternating hot and cold therapy to stabilize the condition and lay a foundation for subsequent rehabilitation training.
When using cold compresses daily, ensure the skin is clean and dry, and avoid applying them to broken or wounded areas to prevent infection. If allergic reactions such as redness, itching, or rashes occur after use, discontinue use immediately and wash the area thoroughly. For individuals with reduced sensation, infants, and the elderly, the duration of use should be strictly controlled to avoid prolonged continuous application that could lead to frostbite. It is generally recommended that each use not exceed the prescribed duration. Cold compresses are only suitable for the early stages of acute injuries or as an adjunct treatment for fever. If symptoms persist or are accompanied by severe discomfort, you should go to the hospital for a professional doctor to assess your condition and develop a comprehensive treatment plan. Do not rely solely on physical cooling and delay proper treatment.
