An infrared therapy pad uses deep-penetrating infrared heat to relieve muscle and joint pain, reduce inflammation, and improve circulation. Unlike surface heat pads, it reaches deeper tissues, promoting faster healing and relaxation. It's especially effective for chronic pain conditions, arthritis, and muscle stiffness. To use it, place the pad on the affected area, adjust the heat setting as recommended, and relax during a typical 20–40 minute session. Regular use can enhance mobility and support long-term pain management without medication.
