Drinking warm water: after the baby has a fever, drink more warm water, let the baby sweat, urinate, so that the body’s metabolic wastes and toxins through the sweat, urine, while supplementing the body’s need for water, which is conducive to lowering the body temperature. 3. antipyretic paste: body temperature 38.5 ℃ can use antipyretic paste to reduce body temperature, antipyretic paste in the gel of moisture vaporization, can be the body of excess heat evaporation, so as to achieve the effect of cooling. 4. Warm water swabbing: Warm water swabbing can also reduce body temperature, water temperature control in 32 ~ 34 ℃ or so, with a warm towel to wipe the baby’s neck, armpits, groin and other blood vessel-rich location to help dissipate heat.
