Is the child has a fever to use hot water or cold water to apply forehead

In general, it is recommended that you choose warm water of more than ten degrees to give your child a local cold compress. The water temperature should not be too hot, otherwise it is not conducive to heat dissipation. In addition to local cold compress, you can also use warm water of about 40 degrees to wipe the whole body and use evaporation to dissipate heat. If the temperature exceeds 38.5 degrees, you should promptly give cooling drugs.
