How long should a newborn be exposed to blue light for jaundice?
If a baby's jaundice requires blue light therapy, it indicates that the jaundice is quite severe and is pathological. Blue light is one of the most effective treatments for jaundice, typically administered either continuously or intermittently. Continuous exposure is generally for a longer duration, such as for more severe conditions like hemolysis or serious infections, which cause a significant increase in jaundice levels, and typically requires 24 to 48 hours of continuous light treatment. If the jaundice is not very severe but still elevated, intermittent light treatment is usually adopted, lasting anywhere from 6 to 16 hours. Generally, if the jaundice does not rebound significantly after light treatment, there is no need for further light exposure. However, if the jaundice rebounds, additional treatment may be necessary. The duration of light therapy for jaundice depends on the baby's condition. If the cause of the jaundice is identified and treated, and the condition stabilizes, the duration of blue light therapy may be reduced. However, if the jaundice repeats or rebounds severely and is associated with significant pathological factors that are not fully controlled, then the treatment duration for jaundice will be longer.
