Generally speaking, a baby with an axillary temperature over 37℃, an oral temperature over 37.4℃, an anal temperature over 37.6℃, and a 24-hour temperature fluctuation over 1℃ is called fever. When a baby has a fever, if the body temperature is measured at around 37.5℃-38℃, it belongs to a low fever with mild symptoms. When the baby has a low fever, moms and dads can do the following things: First, help the baby massage: when the baby has a fever, it will lead to poor blood circulation, you can promote the baby’s whole body blood circulation through gentle massage. In the massage, mom and dad should first rub their hands hot, in order to transfer the heat from their hands to the baby. Second, pay attention to warmth: when the baby has a low fever, it is best to cover the baby with a thin layer of quilt. If you blindly take off your baby’s clothes to dissipate heat at this time, you will instead easily catch a cold and aggravate your condition. Third, keep the air circulation: try to control the indoor temperature at about 20 ℃ and keep the humidity at 50%-60%. Pay attention to open the windows to keep the indoor air circulation, but to prevent the wind through the hall. If the baby’s temperature still continues to rise, mothers and fathers should not arbitrarily give their babies fever-reducing drugs, they can use physical cooling, such as cold water or ice packs to cool down, and at the same time go to the hospital as soon as possible.
