ThermaCare Air-Activated HeatWraps for Neck, Wrist, and Shoulder provide targeted, drug-free pain relief through therapeutic heat. These wraps activate upon exposure to air, delivering consistent low-level warmth to relax tight muscles and increase blood flow for up to 8 hours. The air-activated heat cells use natural ingredients like iron powder, carbon, and salt to generate penetrating heat around 104°F (40°C), mimicking the body's core temperature. Their flexible, ultra-thin design contours comfortably to the neck, wrist, or shoulder, allowing discreet wear under clothing during daily activities. Odorless and portable, they offer on-the-go relief without cords or power sources. Product Specifications Each pack includes 3 single-use HeatWraps, suitable for minor muscle strains, joint pain, or overuse injuries. The wraps feature adjustable straps for a secure fit and promote faster healing by enhancing circulation. Hypoallergenic materials ensure comfort on sensitive skin, though users over 55 should wear over clothing to reduce burn risk.
