The design of our bodies is such that the extent of the ocean of water outside the cells is expanded to have the extra water available for filtration and emergency injection into vital cells. The brain commands an increase in salt and water retention by the kidneys.
This is how we get an oedema when we don’t drink enough water.

Salt is a vital substance for the survival of all living creatures, particularly humans. Water and salt regulate the water content of the body. Water itself regulates the water content of the interior of the cell by entering every cell it can reach. It has to get there to cleanse and extract the toxic wastes of cell metabolisms. Salt forces some water to stay outside the cells, and balances the amount of water that stays outside and inside the cells. There are two oceans of water in the body; one ocean is held inside the cells of the body, and the other ocean is held outside the cells.
