Should children with high bilirubin levels be exposed to more sunlight to reduce yellowing?

Whether children with high bilirubin levels need to be exposed to more sunlight to reduce yellowing needs to be determined based on specific causes. Physiological jaundice can be relieved by moderate sun exposure, but pathological jaundice requires timely medical treatment. Physiological jaundice in newborns usually appears 2-3 days after birth and is related to immature liver metabolic function. Moderate sunlight exposure helps to photoisomerize bilirubin on the skin surface, promoting bilirubin excretion. It is recommended to choose soft sunlight from 9-10am or 4-5 pm, for 10-15 minutes each time, and pay attention to protecting the eyes and genital area. Children with breast milk jaundice can continue breastfeeding while also receiving intermittent sun exposure. Pathological jaundice caused by diseases such as ABO hemolysis, G6PD deficiency, and biliary atresia cannot be effectively reduced by simply sunbathing. When the total bilirubin in the serum exceeds 256 μ mol/L or rises by more than 85 μ mol/L daily, immediate blue light therapy is required. Children with severe hemolysis may require intravenous immunoglobulin or exchange transfusion therapy. Children with congenital biliary malformations often require surgical intervention. Parents should seek medical attention first to determine the type of jaundice when they discover yellow staining on their child's skin and sclera. Sunbathing is only an auxiliary measure for physiological jaundice and cannot replace medical intervention. Children with pathological jaundice should maintain clean skin during treatment, regularly monitor bilirubin levels according to medical advice, pay attention to feeding, mental state, and changes in urine and stool color. Regardless of the type of jaundice, adequate feeding should be ensured to promote bilirubin excretion.
