You can’t recover just by drinking water! Even if you drink water, your body’s fluids may not recover sufficiently. What is spontaneous dehydration?

Drinking only water when rehydrating your body can have the opposite effect. If you continue to drink only water, your body will work to keep the concentration of body fluids constant, and you will excrete excess water as urine. As a result, a phenomenon called spontaneous dehydration occurs, in which the amount of water in the body cannot be restored sufficiently.

At the same time, to prevent further dilution of body fluids, thirst subsides even though dehydration has not occurred, and there is a danger of not being aware of dehydration.
