Sun exposure for infants can effectively reduce the level of bilirubin in the body, thus reducing the degree of yellow staining of the skin and sclera. The bilirubin in the baby’s body will drop after the jaundice is exposed, so the yellow staining of the skin and sclera will slowly decrease, but the time for the baby to be exposed to the jaundice should not be too long, especially in the hot summer, so as not to cause sunburn, and it is better to give the baby sunshine when the wind and sunshine are good.
