It is not recommended to remove jaundice in infants by sunbathing through a glass because jaundice in children is mainly caused by high unconjugated bilirubin in the body. After irradiating children’s skin with blue light, the level of unconjugated bilirubin in children’s bodies will be greatly reduced, which is the principle of blue light irradiation for jaundice. However, the amount of blue light in sunlight is very small, especially after exposure to sunlight through a glass, the amount of blue light that passes through the glass is even smaller, so this way of removing jaundice has very little effect and is not recommended for children. If the jaundice level of children is relatively high, they should go to the hospital specifically to apply blue light therapy device.
