The time to sunbathe for jaundice, if the patient is mildly jaundiced, such as elevated bilirubin is between 17.1-34.2 μmol/L. At this time, patients can consider moderate sun exposure between 9-11 am, or 4-6 pm, usually outdoors, avoiding exposure through glass. Patients with this condition can mildly lower their bilirubin, and if the patient has a more severe bilirubin elevation, it should be actively considered. In the case of infants, blue light exposure is performed in the incubator. Because for sunlight, blue light is only one of its spectrum and is not as effective as blue light for the reduction of jaundice. Therefore, if a newborn has physiological jaundice and the jaundice is severe, blue light exposure in an incubator should be actively considered. In addition, moderate administration of anti-yellowing drugs, such as gardenia yellow granules. If the patient has a combination of sharply elevated glutathione and glutamic oxalacetic transaminase, the patient also needs intravenous infusion or oral hepatoprotective drugs for hepatoprotective treatment, and should usually pay attention to more rest and drink more water.
