Children after bathing fever phenomenon, generally for the indoor environment temperature is too low or the water temperature is too low leading to cold, caused by upper respiratory tract infection. The child itself due to the imperfect function of thermoregulation, generally can not occur shivering heat production, only through the fat brown tissue metabolic heat production. When the indoor environmental temperature is too low or the water temperature is too low, the skin’s defense ability is reduced, the heat production is insufficient, easy to get cold, low immunity, at this time, if the child is exposed to certain pathogenic bacteria, easy to produce upper respiratory tract infections, so that the fever phenomenon after the bath. Children in the bath should pay attention to the room temperature and water temperature, room temperature should be maintained at 26 ℃ ~ 28 ℃, the bath time should not be too long, timely warmth, to avoid getting cold.
