Fénykezelések

Fénykezelések, often translated as light therapy or phototherapy, refers to the use of specific wavelengths of light to treat various medical conditions. This therapeutic approach utilizes the interaction of light with the body's cells and tissues to induce beneficial biological responses. Different types of light, including visible light, ultraviolet (UV) light, and infrared light, are employed depending on the intended application.

One common application of fénykezelések is in dermatology, where it is used to treat skin conditions such as psoriasis, eczema, and acne. UV light, particularly narrowband UVB, has proven effective in managing these inflammatory skin disorders by modulating the immune system's response and slowing down the rapid skin cell turnover characteristic of psoriasis. Blue light therapy is frequently used for acne treatment, targeting the bacteria responsible for breakouts.

Beyond dermatology, fénykezelések has applications in other medical fields. Photodynamic therapy (PDT), which combines a photosensitizing agent with light, is used to treat certain types of cancer and precancerous lesions. Neonatal jaundice is treated with visible blue light, which helps break down bilirubin in the bloodstream. Seasonal affective disorder (SAD) is often managed with bright light therapy, mimicking natural sunlight to regulate the body's circadian rhythm and improve mood. The specific wavelength, intensity, and duration of light exposure are critical factors in the efficacy and safety of any fénykezelés.
