How soon you can take a bath after your fever is reduced depends on your mental state, whether you are dehydrated or not, and how much your body temperature is after your fever is reduced. If you are in a good state of mind and have no dehydration, and if your body temperature remains above 36.3℃, you can take a bath at any time. If you sweat excessively after the fever is gone and you are dehydrated, with thirst and dry skin, you need to rehydrate and increase the intake of liquid or semi-liquid food to replenish energy. Regardless of how long it takes to take a bath after the fever has subsided, it is important to note that the bathing time should not be too long and the water temperature should not be too hot or too cold.
