Luminothérapie, or light therapy, is a treatment that uses specific wavelengths of light to improve physical and mental health. It is commonly used to alleviate symptoms of seasonal affective disorder (SAD), sleep disorders, and certain skin conditions. The therapy typically involves exposure to bright light from a special lamp for a set period each day. The process works by mimicking natural sunlight, which can help regulate the body's circadian rhythms and boost mood. Luminothérapie is considered a safe and non-invasive option, making it accessible for many individuals seeking relief from various conditions related to light deficiency.
