Recommended by healthcare professionals, this reusable, latex-free pack heats quickly in a microwave or stove and can also be chilled for cold therapy, making it a versatile, safe, and travel-friendly solution for fast, effective pain relief. ## Description ReliefPak Moist Heat Packs are the ideal solution to ease aches and pains from arthritis, back pain, muscle strains, stiff neck, sprains, stiff joints, bruises, general soreness and spasms. Why? Because moist heat is better than dry heat and a Moist Heat Pack is more effective than a heating pad. Moist heat is superior in deeper tissue heating and penetrates more than dry heat at the same temperature. Moist heat also changes tissue temperature rapidly. Patients often report quicker relief from moist heat and moist heat has been proven to speed recovery by increasing blood flow to a specific area. From less than an hour in either the stove, microwave or another heating unit, the heat pack delivers up to 30 minutes of hot, moist, therapeutic relief. Once heated and ready to use, handle the pack by the corner tab. Be sure to wrap the heated pack in a towel or covering before use. So versatile, these moist heat packs help treat acute pain, chronic pain, relieve aches and ease soreness and stiffness. They are ideal for recovery use post-injury and post-workout, containing material that conforms to any body part and is pliable when heated, unlike heating pads which can be difficult to maneuver. ReliefPak Moist Heat Packs are designed for use at home or in multi-user environments like clinics, spas, gyms and training rooms. That’s why they’re highly recommended by physiotherapists, physicians, chiropractors, athletic trainers and kinesiologists. The pros know what works best. These heat packs are safe for adults and children and are easy to travel with. To use, simply heat and place on the area to be treated using either a towel or cover. Expected usage will dictate how to care and store the heat pack. If it’s expected the pack is going to be used for regular or frequent treatments, it should be kept in water, either in the heating unit or in a covered pot on the stove. If the pack is expected to be idle and stored for an extended period of time, it should be kept moist and cold. In those instances, place the wet pack in a plastic bag, seal it and store it in the freezer. Please note, heat packs are Latex-free. Review: Great product. - As described. Great product.

During a continuous course of therapy, the pack can be left in the slow cooker on “Warm” whenever it’s not in use, so it’s always ready to go. Don’t use the “Low” setting or you may burn your skin. For that reason, the recommendation to “boil” a pack is not only not necessary, but could make this pack dangerously hot—and it might damage the pack over time, shortening its useful life. FYI, some small clinics use slow cookers instead of the large commercial water baths that can hold multiple packs. I was surprised to see that a rehab supplies seller said to put it in a hot towel cabinet. I would recommend confirming that with the manufacturer before trying it. These packs are designed to be used wet, and you’re not supposed to ever let them dry out after the first use, which a hot towel cabinet would almost certainly do. I would definitely NEVER microwave one while dry (as you would a rice pack). Also, either get a cover that is designed for one of these or wrap it in a thin towel before applying it to the treatment area—you normally wouldn’t want to put it directly in contact with your skin. **Q: How do you store this between uses at home? I have been told to freeze it so it stays moist and does not mold. Is that correct?** A: I heat mine in a large oval slow cooker (Crock Pot) on the “Warm” setting, and use a pair of cooking tongs to both remove a heated pack and to push a used back into the water for reheating. During a continuous course of therapy, the pack can be left in the slow cooker on “Warm” whenever it’s not in use, so it’s always ready to go. Storing in the freezer is necessary only when you’re in between courses of therapy. Don’t use the “Low” setting or you may burn your skin. For that reason, the recommendation to “boil” a pack is not only not necessary, but could make this pack dangerously hot—and it might damage the pack over time, shortening its useful life. FYI, some small clinics use slow cookers instead of the large commercial water baths that can hold multiple packs. Also, either get a cover that is designed for one of these or wrap it in a thin towel before applying it to the treatment area—you normally wouldn’t want to put it directly in contact with your skin. **Q: Can you use it as a cold pack?** A: After you soak it for the first time,there's no reason why you can't use it as a cold pack. **Q: Is this to big for shoulders?** A: Its too cumbersome for a shoulder you need to use the cervical. It can be used for the hip, wrapping it around. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product. *by X***S on 29 April 2018* As described.
