Ljósmeðferðar

Ljósmeðferðar refers to therapeutic applications of light. This broad category encompasses various treatments that utilize specific wavelengths of light to address a range of medical conditions. Different types of light therapy exist, each employing distinct principles and technologies.

One common form is phototherapy, often used for skin conditions like psoriasis, eczema, and jaundice in newborns. Phototherapy typically involves exposure to ultraviolet (UV) light, either broad-spectrum or narrow-band. Another significant application is light therapy for seasonal affective disorder (SAD), a type of depression linked to changes in seasons and reduced sunlight exposure. This treatment involves sitting in front of a special lamp that emits bright light.

Furthermore, light is employed in more specialized medical procedures. Laser therapy, for instance, uses concentrated beams of light for surgical interventions, pain management, and cosmetic treatments. Low-level laser therapy (LLLT), also known as photobiomodulation, uses light of specific wavelengths to promote tissue healing and reduce inflammation. The precise mechanism of action often involves stimulating cellular activity and energy production. The effectiveness and protocols for ljósmeðferðar vary depending on the condition being treated and the specific light source used.
