How 43° Works

Cold Therapy is used after an injury to the tissue or muscle. Ice/gel packs are commonly used to speed up healing and reduce pain. Optimal healing and comfort occur when the skin is maintained at a temperature between 41-59°F. This temperature range is considered Therapeutic Zone (TZ). Anything above 59°F does not promote faster healing and a temperature below 39°F is dangerous to your skin and can cause ice burn, nerve damage, and other harmful skin issues. The 43 Pad is designed to keep the skin temperature safely above 43°F while maintaining your muscle and deep tissue layers in the TZ for an extended period of time.
