What does dehydration indicate?

Dehydration indicates that fluid loss is exceeding the intake of fluids. This condition occurs when the body loses more fluids than it takes in, leading to an imbalance that can impair bodily functions. Signs of dehydration can include thirst, dry mouth, fatigue, and reduced urine output. It is crucial to recognize and address dehydration promptly, particularly for lifeguards who may be exposed to hot weather and physical exertion, which increases fluid loss through sweat. In contrast, balanced fluid intake, excessive water consumption, and normal hydration levels suggest states where fluid balance is maintained, either through adequate consumption or appropriate hydration. Understanding dehydration is essential in a lifeguard's role, as it affects not only their own well-being but also the health and safety of those they supervise.
