Valokuvoterapia

Valokuvoterapia, often translated as phototherapy or light therapy, is a medical treatment that uses specific wavelengths of light to manage certain health conditions. It is commonly employed in dermatology to treat skin disorders such as psoriasis, eczema, vitiligo, and seasonal affective disorder (SAD). The effectiveness of valokuvoterapia relies on the interaction of light with the body's cells and biological processes.

In dermatology, ultraviolet (UV) light, particularly narrowband UVB, is frequently used. This light can help reduce inflammation, slow the growth of abnormal skin cells, and stimulate the production of vitamin D. Treatments are typically administered in a controlled environment, such as a clinic, under the supervision of a healthcare professional. The duration and frequency of sessions vary depending on the condition being treated and the individual's response.

For SAD, valokuvoterapia involves exposure to bright light from a special lamp, usually for a set period each day. This is thought to help regulate the body's internal clock and improve mood by mimicking natural sunlight. While generally safe, valokuvoterapia can have side effects, including skin redness, itching, and, in rare cases, increased risk of skin cancer with prolonged UV exposure. Therefore, it is crucial to undergo this therapy under medical guidance.
