Whatever may the cause of the fever be, it is natural that you will lose water during fever in the form of sweat, sneezes, etc. Replenishing the water content of the body is important if you want to recover quickly. Keep drinking clean water from time to time. Sports drinks, rehydrate solutions, beverages, etc. may also be included in small amounts. For children, rehydrating electrolyte solutions are the best choice.
Keep yourself cool
Unlike the common belief, do not keep the body too hot during fever. It will only increase it further. Try to keep your body as cool as possible. Comfy, lightweight clothes as well as thin blankets are recommended. You can put the fan on at intervals to cool a stuffy, humid environment.
