Each day, people are exposed to infrared light via natural sunlight. While the risks of infrared lamps or an infrared heating pad are minimal, there are some possible side effects to consider. While rare, it is possible to suffer a thermal or heat injury—and you may not even realize it because not all of these injuries result in pain.
There are also certain groups that should not use infrared therapy. This includes people who are sick, those with heart diseases, and women who are pregnant.
