What happens if you don't drink water?

Dear Ilya! In the complete absence of water entering the body, death (death) occurs in 3-4 days, and in a dry and hot climate - in 1-2 days. The loss of only 9% of water is a threat to human life, and 10% of its loss is critical with a high risk of mortality. All physiological and enzymatic processes in our body occur in the aquatic environment. In addition, water is the main constituent of blood plasma, maintaining a certain pressure in the vessels and providing an adequate blood supply to all internal organs and systems. With a lack of water, dehydration of varying degrees occurs, which manifests itself from a feeling of thirst and dryness to severe disorders of blood circulation, breathing, convulsive syndrome, vomiting and loss of consciousness up to coma

It has been proven that a person consists of 70% water. Water for a person and for all living things is life. Accordingly, its absence is equal to death. So, if you don't drink water (and also don't eat food, because almost all food contains some percentage of water), then you can die .
