Newborn’s skin area is large, fat is relatively thin, so the warmth effect is poor, at the same time, poor thermoregulation ability, with the surrounding indoor temperature, wear clothes and other reasons the body temperature will fluctuate, but not generally do not exceed 37.5 degrees. If the newborn’s temperature exceeds 37.5 degrees, accompanied by crying, loss of appetite and other symptoms, you need to consider the possibility of fever, if the indoor temperature is too low, the body’s energy can not meet the demand for heat production, there may be neonatal scleroderma, so find the newborn’s temperature is abnormal or other abnormal symptoms, bring to the hospital in a timely manner for relevant examinations, to give the corresponding treatment.
