What kind of assistance is needed: Hello, home physical fever reduction methods, and what other anti-inflammatory medications can be used?

Doctor's answer:

Physical cooling methods are slower in reducing temperature, but they have no side effects on the child's body, so they can be considered a relatively safe method for cooling.
Advice:
Method 1: Soak a towel in lukewarm water (the temperature should feel neither cold nor hot, approximately 38–41°C), wring it out slightly, and then wipe the child's neck, arms, chest, back, thighs, and other areas. Focus on the major blood vessel areas such as the elbow creases, armpits, and neck, and wipe them more thoroughly until they turn slightly red. This way, as the water evaporates, it can carry away a significant amount of heat, helping to lower the body temperature.
Method 2: Place an ice pack or cold towel on the child's forehead. This can reduce oxygen consumption in the brain and help lower body temperature while protecting the brain.
