Many experts rate water second only to oxygen as essential for life. All living things need water for growth and survival.
The human body is made up of 75% water and the brain is made up of 85% water so, as with any living thing, dehydration leads to decreased efficiency. If you deprive a fruit tree of water, the fruit shrivels up and eventually will die, and so the cells of the body mimic the process.
The role of water in the body is a simple but crucial one. A human being can survive for 3/4 weeks without food but only a few days without water. Quite simply, the organs of the body cannot function. Water replenishes the body’s cooling system, and it is essential in the processes of digestion, absorption, circulation and lubrication of the joints.
Every cell of the human body is a living thing with a function. Dehydration is the loss of fluids from the body and thirst is normally the first physical sign. But by the time you feel thirsty the process of internal dehydration has already started. Among other symptoms, you may not be able to concentrate, your blood pressure will begin to drop, you heart rate will increase as it has to work harder, and the kidneys become less efficient.
