hydration physiology

Hydration physiology refers to how the body maintains a proper balance of fluids to function effectively. Water is essential for regulating body temperature, transporting nutrients, removing waste, and enabling chemical reactions. When you're well-hydrated, your body keeps blood and tissues adequately moist, supporting all biological processes. If you don't drink enough fluids, dehydration occurs, leading to symptoms like thirst, fatigue, and impaired function. Conversely, too much water can cause overhydration or hyponatremia, diluting blood minerals. The body constantly adjusts through mechanisms like thirst, urine production, and releasing hormones to keep fluid levels stable for optimal health.
