Original Thermophore Automatic Moist Heat Pack is designed with a special hand-held switch. Just press for heat, release to cool and alternate as often as you like. If you happen to doze off and your hand relaxes, the unit will cool as a safety feature.

Professional-quality intense moist heat can also be used at home for therapy any time of the day or night. Thermophore® is the brand most often used and recommended by doctors, physical therapists, and other medical professionals.
