[[Depression (mental illness)|Depression]], [[sleep disorder|sleeping problems]], [[bipolar disorder]] and many skin conditions are treated with this therapy. The therapy consists of exposing the patient to a light source (a table [[lamp]], for example). The light source usually emits the full spectrum of light. Sometimes, this has to be done at a specific time of day. When it is used for skin conditions, it is usually called '''phototherapy'''. Example conditions where phototherapy is used are [[psoriasis]] and [[atopic dermatitis]]. Light therapy should generally not be used, in the case the patient also suffers from certain diseases of the eyes. Certain drugs make people more sensitive to light. People taking such drugs should also not use light therapy. {{med-stub}} [[Category:Therapy]]
