Light therapy: medicine or not?
Light therapy has a positive biological effect because the body needs light to be healthy. Natural sunlight has been used as a treatment for centuries, although we now know that certain wavelengths can be both beneficial and harmful. For example, ultraviolet (UV) light therapy is used effectively to treat chronic skin conditions. However, exposure to ultraviolet light should be done only in moderation, as it is known to damage cells and even cause skin cancer. Based on years of research, scientists have identified a “therapeutic window” of certain wavelengths – red and near-infrared light – that appear to have significant biological benefits without any of the previously mentioned side effects.
