FACT CHECK #6R8JK-A8

WHAT WE FOUND

The claim that the human body consists of 90% water is false and contradicts established scientific consensus [4, 9]. High-credibility sources, including the U.S. Geological Survey and peer-reviewed research, state that the average adult human body is composed of approximately 50% to 60% water [2, 6, 12]. While specific organs such as the lungs are nearly 90% water 2, and some other organisms can reach 90% water weight 1, the human body as a whole does not reach this level. The highest water percentage in humans is found in infants, who are approximately 75% to 78% water [5, 8, 9]. This percentage typically decreases with age, falling to as low as 45% in the elderly [6, 8, 9].
