We at ingfit are huge advocates of using water to hydrate your body as part of a healthy lifestyle. We’re always being told that we don’t drink enough water, but when it’s broken down like this, it’s clear why it’s not only essential for all living things to survive, but also how important hydration is for a healthy body!
Here’s the first of series of short articles that caught our attention.

Water : Human body’s major component
On average, the body of an adult human being contains 60% water. Most of the water in the human body is contained inside our cells.
In fact, our billions of cells must have water to live.
The total amount of water in our body is found in three main locations: within our cells (two-thirds of the water), in the space between our cells and in our blood (one-third of the water). For example, a 70-kg man is made up of about 42L of total water.
- 28 litres is intracellular water
- 14L is found in extracellular fluid of which
- 3L is blood plasma,
- 1L is the transcellular fluid (cerebrospinal fluid, ocular, pleural, peritoneal and synovial fluids)
- 10L is the interstitial fluid (including lymph), which is an aqueous medium surrounding cells. (1)
Actually, the amount of water a body contains varies according to certain contexts : The body of a newborn is composed of more water (75%) than that of an elderly person (50%). Also, the more muscular a body is, the more water it contains. Conversely, the more fat in the body, the less water the body contains – as body fat has little water.
Also, all our vital organs contain different amounts of water: the brain, the lungs, the heart, the liver and the kidneys contain a large quantity of water – between 65 to 85% depending on the organ (2), while bones contain less water (but still 31%!).
For all those reasons, water is life.
