In most cases, children with fever are wiped with a hot towel, because the application of a hot towel on the child’s body will help the child’s blood circulation to flow smoothly, so that the child’s skin will turn red, so that the heat dissipation effect will be better. In addition, the water in the hot towel can also play the role of evaporation, so as to be able to take away the excessive heat in the child’s body. Hot towels do not significantly irritate the child’s skin, do not cause the skin to appear contracted, and even goose bumps will not arise and so on. Cold towels, on the other hand, tend to irritate children’s skin more and can cause skin chills, and this is when children tend to dissipate heat inappropriately.
