The average percentage of water in the human body is approximately 60%. However, this can vary depending on factors such as age, gender, and body composition.
No, the human body is not 90% water. As mentioned earlier, the average percentage of water in the human body is around 60%. This myth likely stems from the fact that infants have a higher percentage of water in their bodies, which can be as high as 75%.
If the percentage of water in the human body drops below 70%, it can lead to mild dehydration. Symptoms of dehydration include thirst, dry mouth, fatigue, and dizziness. It is important to drink enough water and stay hydrated to avoid these symptoms.
No, it is not true. The average person can survive without water for about 3-4 days, depending on factors such as climate and physical activity. A person's body will start to shut down and experience severe dehydration if they go without water for too long.
The percentage of water in the human body is higher than most other living organisms. For example, plants have a lower percentage of water, usually around 80-90%, while animals have a higher percentage, typically around 70%. However, there are some organisms, such as jellyfish and sea cucumbers, that have a higher percentage of water in their bodies than humans.
