Human beings spend a third of their lives in sleep. While we sleep, some important functions such as the recovery of homeostasis or the consolidation of learning are carried out. For these reasons, people with insomnia suffer a significant alteration of their daytime functioning. Exposure to bright light, whether from the sun or from artificial lamps, is known as phototherapy or light therapy and it could be an important alternative to conventional treatments used to treat different types of insomnia.
