what percentage of your body is water?

Answer 1

I found this perspective posted by Jeffrey Utz, MD, Neuroscience, pediatrics, Allegheny University:

"Different people have different percentages of their bodies made up of water. Babies have the most, being born at about 78%. By one year of age, that amound drops to about 65%. In adult men, about 60% of their bodies are water. However, fat tissue does not have as much water as lean tissue. In adult women, fat makes up more of the body than men, so they have about 55% of thier bodies made of water. Fat men also have less water (as a percentage) than thin men.

So you can see three possible reasons for the discrepancies you have found:

1) Babies and kids have more water (as a percantage) than adults.
2) Women have less water than men (as a percentage).
3) Fat people have less water than thin people (as a percentage).

A forth reason is that different people measure per cent water a little differently, causing small differences in the answer."

Answer 2

The percent water in the entire body by weight varies with age, sex, and physical conditioning. Heart and lung contain the most water, about 80%. Fat (about 20%) and bone (about 43%) are among the lowest. Therefore, the total body is an average of all organs, blood, and extracellular fluids. Several physiology texts place average young men at 60% water, and young women at 50% water, the difference due to relatively more fat in females. Thus, a 70 kg young man has about 42 kg (or 42 liters) or water. With age fat increases and muscle decreases, so that in old age the body may contain only 45% water. Infants, by contrast, average 73% or more.

However, the human brain is composed of 70 percent water. About 83 percent of our blood is water, which helps digest our food, transport waste, and control body temperature. Each day humans must replace 2.4 litres of water, some through drinking and the rest taken by the body from the foods eaten.

Answer 3

Water is your body's principal chemical component, comprising, on average, 60 percent of your weight. Every system in your body depends on water. For example, water flushes toxins out of vital organs, carries nutrients to your cells and provides a moist environment for ear, nose and throat tissues.

Lack of water can lead to dehydration, a condition that occurs when you don't have enough water in your body to carry out normal functions.

Answer 4

80 ideally
