Heat therapy application can help provide pain relief through several mechanisms
- Heat therapy dilates the blood vessels of the muscles. This process increases the flow of oxygen and nutrients to the muscles, helping to heal the damaged tissue.
- Heat stimulates the sensory receptors in the skin, which means that applying heat to the lower back will decrease transmissions of pain signals to the brain and partially relieve the discomfort.
- Heat application facilitates stretching the soft tissues around the spine, including muscles, connective tissue, and adhesions. Consequently, with heat therapy, there will be a decrease in stiffness as well as injury, with an increase in flexibility and overall feeling of comfort. Flexibility is very important for a healthy back.
- Compared to most therapies, heat therapy is quite inexpensive. Heat therapy is also easy to do – it can be done at home while relaxing, and portable heat wraps also make it an option while at work or in the car.
- A hot pack helps promote the natural healing process of your body. Better healing means less toxins that may cause pain and swelling.
