👉 Hourly fluid, also known as total body water (TBW), refers to the amount of water present in the human body at any given time, encompassing all bodily fluids including plasma, interstitial fluid, and intracellular fluid. It is crucial for maintaining homeostasis, supporting metabolic processes, regulating body temperature, and ensuring proper organ function. The concentration of hourly fluid can vary based on factors like hydration status, diet, physical activity, and overall health. Typically, the body contains about 60% water in an average adult, with the remainder distributed among various compartments. Understanding hourly fluid dynamics is essential for assessing hydration levels and overall health, as imbalances can lead to conditions such as dehydration or edema.
