As the name suggests, infrared light therapy is simply a form of therapy performed using infrared light. This infrared light is part of the electromagnetic spectrum, which includes, among other things, the light we use to see, the radio waves we use to communicate, and the heat we use to cook.
There are many areas where infrared red light therapy has helped. One of these, which probably accounts for a very large proportion of infrared light therapy uses, is in the treatment of acne. This is an area where infrared rays have shown good treatment effectiveness, leading many people who suffer from acne and who can afford this type of therapy to choose this type of therapy.

Thus, infrared light is a type of electromagnetic energy. In the electromagnetic spectrum, it lies somewhere midway between the light we see (visible light, which has shorter wavelengths) and radio waves (which have longer wavelengths than infrared light), which is the subject of our discussion here.
Infrared light therapy is an example of what is known as phototherapy, in which only light has a therapeutic effect. This is a drug-free therapy. The exact benefits vary, but what happens in all cases is that direct application of light to the body improves the health of the user.
People with diabetic sores also usually benefit greatly from infrared light therapy.
People with severe chronic pain have also found relief from infrared therapy, as are people with high blood pressure who are always at risk of other dreaded diseases such as heart attack and stroke if no action is taken to reduce the pain.
