Light therapy is a treatment that uses specific wavelengths of light to improve health and well-being. It is often used to help with conditions like seasonal affective disorder (SAD), where people feel depressed during the darker months of the year. By exposing the eyes to bright light, this therapy can help regulate circadian rhythms and boost mood. In addition to mood disorders, light therapy can also benefit skin conditions such as acne and psoriasis. Special devices, like light boxes or handheld lamps, emit the necessary light to promote healing. This non-invasive treatment is generally safe and can be done at home or in a clinical setting.
