valohoitoon

Valohoito, also known as phototherapy, is a medical treatment that uses specific wavelengths of light to treat various conditions. The most common application of valohoito is in the treatment of neonatal jaundice. In newborns, the liver may not be mature enough to process bilirubin effectively, leading to its buildup in the blood. Bilirubin is a yellow pigment, and its excess can cause the skin and eyes to appear yellow. Valohoito converts bilirubin into a less toxic form that the body can excrete more easily, often through urine and stool. This is typically achieved by exposing the infant to blue-spectrum light, which penetrates the skin and interacts with the bilirubin.

Beyond neonatal care, valohoito is also utilized for certain skin conditions. Dermatologists may prescribe phototherapy for conditions such as psoriasis, eczema, and vitiligo. Different types of light, including ultraviolet B (UVB) and ultraviolet A (UVA) light, are used depending on the specific dermatological issue. These treatments are administered under strict medical supervision in controlled environments to minimize risks associated with UV exposure, such as sunburn and an increased risk of skin cancer with prolonged or excessive use. The duration and frequency of valohoito sessions are tailored to the individual patient's needs and the severity of their condition.
