Most of the human body is water, with an average of roughly 60%. The amount of water in the body can change slightly with age, sex, and hydration levels. While the average percentage of water...
Up to 60% of the human adult body is water. According to Mitchell and others (1945), the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.
Water is your body's principal chemical component and makes up about 50% to 70% of your body weight. Your body depends on water to survive. Every cell, tissue and organ in your body needs water to work properly. For example, water: Gets rid of wastes through urination, perspiration and bowel movements. Keeps your temperature normal.
The adult human body averages ~53% water. [7] This varies substantially by age, sex, and adiposity. In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. [8]
The average percentages of water in the human body vary by gender, age, and weight, though they'll remain above 50 percent for most of your life. Learn how much of your body is water, where...
About two-thirds of the body’s water is inside cells (intracellular fluid), while one-third is outside of cells (extracellular fluid). About 20% of the body’s water is in blood plasma. The amount of water varies in different organs.
In a large study of adults of all ages and both sexes, the adult human body averaged ~65% water. However, this varied substantially by age, sex, and adiposity (amount of fat in body composition). The figure for water fraction by weight in this sample was found to be 58 ±8% water for males and 48 ±6% for females. [3]
The amount of water in the human body ranges from 45-75%. The average adult human body is 50-65% water, averaging around 57-60%. The percentage of water in infants is much higher, typically around 75-78% water, dropping to 65% by one year of age.
Our water calculator will help you easily estimate how much water you need per day including how much of it you will need to drink in the form of fluids (pure water or beverages). The outputs of our water intake calculator are in liters, milliliters, cups (equivalent to a standard glass), and ounces of water.
The normal total body water volume range is 58 ± 8% for males and 48 ± 6% for females. The body water is broken down into the following compartments: Intracellular fluid (2/3 of body water) is the fluid contained within cells. Extracellular fluid (1/3 of body water) is the fluid contained in areas outside of cells and consists of:
