Total Body Water is the complete volume of fluids present in the body, expressed as a percentage of one's total body weight.

Water plays a vital part in providing and maintaining overall health. More than half of the human body is composed of water, and it serves as a regulator of body temperature while aiding in waste elimination. Continuous water loss occurs through processes such as urination, sweating, and respiration, emphasizing the importance of consistent replenishment.

The daily fluid requirement varies from person to person and is influenced by factors like climate and physical activity levels. Proper hydration supports concentration, sports performance, and overall well-being.

Health experts recommend a daily intake of at least eight 8-ounce glasses of fluids, with a preference for water or other low-calorie beverages. For those engaging in regular training, increasing fluid consumption is essential to ensure optimal performance at all times.

For reference, the typical Total Body Water percentages for a healthy individual are as follows:

Females: 45% to 60%
Males: 50% to 65%
