Drinking more water when your child has a fever is very useful and beneficial in relieving the condition and reducing the fever. Because the principle of reducing fever, whether it is taking antipyretic drugs or antipyretic drugs, the effect of reducing fever is only through the child’s sweating, evaporation, cooling and heat dissipation. Children in a dehydrated state are less effective in taking antipyretics, and the side effects of taking antipyretics in a dehydrated state are greater, especially on liver and kidney function, so it is advocated to give children more water when they have a fever. If you can’t drink water, you can add more water to your child’s food, such as soaking milk to make it thinner, such as eating more thin water-like foods like rice and noodles for better results.
