The heat therapy, also known as thermotherapy, should be used for muscle spasms, muscle and menstrual cramps, aches, muscle pain or stiffness, and arthritis pain.
The cold therapy, also called cryotherapy is preferred in case of sprains, tears, sprains, minor burns or headache. It is important to avoid cold therapy in case of wounds, as this may interfere with wound healing.
Absolutely, the gel used in the Gel-Pak ™ compresses is specifically formulated to be heated even if it has been frozen previously. However, if gel compress has been in the freezer, let it thaw to room temperature before heating in the microwave.
It is recommended not to apply the compress directly to the skin to avoid burns or frostbite in case of excessive temperature. The compress should be placed in its cotton bag or a towel. As temperatures of freezing and warming vary from one device to another, it is important to check the temperature of the compress prior to application.
