How Does
Heat Therapy Work?


Heat stimulates thermoreceptors, blocking pain signals to the brain.


Applying heat increases circulation to the injured area. Increased blood flow means more oxygen and nutrients are sent to the damaged tissue, which promotes healing.


Heat helps relax damaged, tight, and sore muscles, to improve flexibility and decrease stiffness.

  • ThermaCare® patented heat cell technology combines iron, oxygen, water, and salt in single-use HeatWraps. The heat cells produce real heat to stimulate healing right where you need it. ThermaCare® HeatWraps work by allowing real heat to penetrate damaged tissue, which increases blood flow and accelerates the body’s natural healing process.

  • Each heat disc is designed to heat to about 104°F (40°C) for 8 hours. That’s just above your body's normal core temperature of 98.6°F.

  • ThermaCare® relieves pain by going to work right at the site of pain. It relaxes the muscle and increases blood flow in the area. On the other hand, oral pain medications have to be ingested and provide relief by working through the bloodstream and stopping the production of prostaglandins.

    "I put these on in the morning before heading to work. Feels good and gives me relief to get through the day. Lasts hours loosening tense muscles, longer than many rubs. Helps my backache."

    "Early morning sports - tennis or golf or skiing - are killers on my husband's back, so we always keep ThermaCare with us. We wear them skiing too because they keep us warm even on the chilliest days on the chairlift!"
