Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, neonatal jaundice, and skin wound infections.
Blood irradiation therapy is an alternative medical procedure in which the blood is exposed to low-level light (often laser light) for therapeutic reasons. [1] The practice was originally developed in the United States, [1] but most recent research on it has been conducted in Germany (by UV lamps) and in Russia (in all variants).
Rapid flickers in intensity of light may trigger or aggravate photosensitive epilepsy, epileptic seizure, or migraine headaches. [4] Conditions that may include sensitivity to light include vertigo and chronic fatigue syndrome. Controlled application of artificial light can be used in a program of light therapy to treat some disorders.
UVB light therapy can be used to target single patches or widespread areas, often combined with topical treatments. While some forms of light therapy can risk severe burns, most side effects are ...
Light-emitting diode therapy (LEDT) is a clinical approach that applies different wavelengths of light to cure diseases or conditions with skin-safe lights. Following NASA's innovation in the 1990s with Light Emitting Diodes (LEDs) that emit a specific narrow light spectrum, LED Therapy (LEDT) showed significant potential. [ 1 ]
Furthermore, in addition to these dangers, light therapy may not be an as effective choice in general. Said Palep, "At-home LED devices use lower frequencies, so [they] haven’t proven to be as ...
Ultraviolet light therapy or ultraviolet phototherapy is a treatment for psoriasis, atopic skin disorder, vitiligo and other skin diseases. There are two main treatments: UVB that is the most common, and PUVA.
Artificial sunlight is useful in treating and preventing seasonal affective disorder (also known as winter depression, which causes depression symptoms specifically in winter), [3] and delayed sleep phase syndrome, in which the circadian rhythm (the rhythmic alternation between daylight and nighttime behavior and bodily states) is disturbed and the person falls asleep much later than he or she ...
