HeatWraps: Healing with Heat

From hot baths to heating pads to hot water bottles, heat therapy is a well-known remedy to help ease muscular pain, and reduce soreness and inflammation. ThermaCare® technology combines iron, oxygen, water and salt in single-use HeatWraps to produce real heat and stimulate healing right where you need it. The patented technology in ThermaCare® HeatWraps works by allowing real heat to penetrate damaged tissue, increasing blood flow to the source of pain to accelerate healing and relieve pain. It works differently than other patches and creams, which mask pain instead of healing it.

“The advent of therapeutic heat wraps (e.g. ThermaCare®) has revolutionized thermotherapy,” wrote W. Steven Pray, Ph.D., a professor and author of the respected pharmacists’ guide, Nonprescription Product Therapeutics (Lippincott Williams & Wilkins, 2006).1

Pray and other medical experts point to several principal areas where heat wraps such as ThermaCare® have been game changers. The biggest innovation? Portability. One study published in the American Pain Society equates the benefit of a heat wrap with that of warm whirlpool therapy except that the heat wrap lets its user be on the go.2

“Heat wraps worn in direct contact with the skin ... enable patients to remain mobile and active while receiving treatment,” reads the study called, ”A New Look at Heat Treatment for Pain Disorders.”’(APS Bulletin • Volume 15, Number 1, Winter 2005). “As a result, patients retain control over their own care and pain management. This can increase both treatment time at home and allow them to participate in other activities.”3

The studies say other key innovations include:

  • Low-level heat provided by ThermaCare® HeatWraps may be safer than that obtained with potentially hazardous electric heating pads
  • ThermaCare® HeatWraps maintain the heat at a constant temperature over the 8-hour wearing time
  • ThermaCare® HeatWraps can be worn during work or recreational activities so that the patient has an uninterrupted
  • Continuous relief
