                                For the average adult male, water constitutes about 60% of total body weight, which means a 70kg man has approximately 42 liters of total body water. This vital fluid component is essential for nearly every bodily function, from regulating temperature to transporting nutrients throughout the body. Maintaining a proper fluid balance is critical for overall health and performance.
