Although some jaundice can cause drowsiness, there is no such concept as drowsiness in the case of jaundice. Jaundice includes physiological jaundice and pathological jaundice, physiological jaundice patients are due to the short life span of red blood cells after birth, which generally does not affect the health of the patient, pathological jaundice patients may have symptoms of drowsiness. Newborns need 18-20 hours of sleep and 2-3 month old infants need 16-18 hours of sleep. If the sleep time exceeds the above, it is considered to be related to narcolepsy.
