how much is the human body water

Question

The average adult human body is composed of about 60% water [1, 2, 3]. This percentage can vary depending on several factors, including:

Answer 1

• Age: Babies and young children have a higher percentage of body water (around 75%) compared to adults [2]. As we age, the percentage of water in our bodies tends to decrease.
• Sex: Women typically have a slightly lower percentage of body water than men due to differences in body composition (women generally have more fat tissue, which contains less water).
• Weight: People with a higher percentage of body fat tend to have a lower percentage of body water, as fat tissue contains less water than muscle tissue.
• Hydration levels: Dehydration can significantly decrease the percentage of water in your body, while proper hydration can bring it closer to the average 60%.
