UV light, particularly blue light, is commonly used in the treatment of neonatal jaundice. This condition, also known as hyperbilirubinemia, occurs when there is a high level of bilirubin in a newborn's blood, causing yellowing of the skin and eyes. The process, known as [phototherapy]() or light therapy, involves exposing the baby to a type of UV light that helps break down bilirubin into a form that can be more easily excreted from the body.
