Sun exposure time for neonatal jaundice cannot be generalized, but it is usually recommended to sunbathe for 10-30 minutes each time, about 2 hours a day. The length of sun exposure for neonatal jaundice is closely related to the season and the strength of the sun. It is usually recommended to sunbathe before 10:00 a.m. and after 4:00 p.m. The duration is recommended to be around 10-30 minutes. If the UV rays are strong and may burn the child’s skin, the time should be appropriately shortened to 10 minutes per sun exposure. However, it is worth noting that sunbathing through glass is not very useful. There is a strict time limit for sunbathing for neonatal jaundice, about 2 hours a day is more suitable. If a newborn has high jaundice values, consistent with pathological jaundice, hospitalization is recommended for standardized blue light treatment to prevent nuclear jaundice and bilirubin encephalopathy. Newborns have a weak resistance and are easily exposed to cold, so they need to pay attention to keeping warm and avoiding the wind when sunbathing, as well as protecting their eyes from direct sunlight and paying attention to hydration.
