Deep Heat Muscle Rescue Heat Spray is a warming pain relief spray designed for topical use. It's ideal for alleviating discomfort in muscles, tendons, joints, and bones, as well as lower back and thigh pain, sprains, and strains. Suitable for use before and after exercise. This spray generates penetrating warmth in aching, injured, or sore muscles. It combines pain-relief ingredients with heat therapy, which increases blood flow to relax overstretched muscles and re-oxygenate tissues, stimulating the natural healing process. Using heat therapy before exercise can help prepare your muscles by increasing blood flow and flexibility, reducing the risk of injury. However, avoid using heat therapy immediately after strenuous exercise or an injury, as it can increase circulation at a time when cooling therapy is recommended. Always read the label for safety and usage instructions.
