Understanding Hydration

Water is essential for life.

Your body depends on water to survive. Every cell, tissue, and organ in your body needs water to work correctly.

Water plays many important roles within the body. Water is the major part of most of the body’s cells (except for fat cells) and it also cushions and lubricates the brain and the joints. It transports nutrients and carries waste away from the body cells. It also helps regulate body temperature by redistributing heat from active tissues to the skin and cooling the body through perspiration.

Water is the main constituent of the human body: it is normally about 60% of body weight in adult males, and is slightly lower, about 50-55%, in females due to their higher proportion of body fat. The muscles and the brain are about 75% water, the blood and the kidneys are about 81%, the liver is about 71%, the bones are about 22% and adipose tissue is about 20%.

The body requires water to survive and function properly. Humans cannot live without drinking for more than a few days – depending on weather, activity levels and other factors – whereas other nutrients may be neglected for weeks or months.
