Light therapy is a therapy that involves exposure to artificial light. It has been used since antiquity but has developed strongly since the 1980s. This therapy aims to reproduce the white light of the sun in order to compensate for the lack of light that we have to face during the winter period. Indeed, in spring, we receive between 10,000 and 100,000 lux of light, while in winter, we receive only 1,000 on average.

This discrepancy in brightness can impact our mood and in some cases trigger seasonal affective syndrome. This syndrome is manifested by a dysfunction of the sleep rhythm, a lack of energy, weight gain or even a gloomy mood. It is a syndrome that in some cases can turn into seasonal depression. Thus light therapy is a technique whose benefits were recognized by the High Health Authority in 2007 to fight against seasonal depression. But also light therapy can be used to treat other disorders such as chronic pain, wounds, wounds, ulcers, inflammation, arthritis, skin problems (acne, psoriasis…)…

Indeed, when we expose ourselves to a light therapy lamp, a biological reaction occurs. The ganglion cells located behind the retina capture light rays and send a message to the cerebral nucleus. The latter allows us to regulate our biological clock over a period of 24 hours. And other areas of our brain are activated like the hypothalamus. Thus hormones are secreted and help regulate our cycles of wakefulness, sleep or even our mood. Interest in light therapy continues to grow, with more and more individuals doing home sessions. But also some hospitals offer light therapy sessions. However, it is recommended to have a session to have a medical opinion, to consult an ophthalmologist and to use a suitable lamp such as the Ludmila lamp.
