Light therapy (Heliotherapy) - Definition

Definition


Light therapy is a technique used to treat depression and insomnia through exposing a patient to light rays which mimic those emitted by the sun. Many individuals are sensitive to seasonal changes and suffer seasonal depression when daylight diminishes during winter. By exposing a patient to a white light without infrared or ultraviolet qualities, light therapy serves to rebalance the secretion of melatonin, a hormone that takes part in the regulation of the biological clock.
