How Heat Helps
Though it is usually a very simple form of treatment, heat therapy is actually quite ingenious in the way that it relieves pain and muscle stiffness. When applied to sore areas of the body, heat helps to dilate your blood vessels. This encourages blood to rush to the affected area, flushing out toxins and other wastes. This blood also brings oxygen to the site, which helps to repair soft tissue, encourage muscle tone, and relax muscles contractions.
