What does dehydration refer to in the human body?

Dehydration in the human body specifically refers to a state where there is an abnormally low level of water within the body's tissues. This condition occurs when the body loses more fluids than it takes in, leading to an imbalance that can affect various bodily functions. Adequate hydration is essential for maintaining normal physiological processes, and when dehydration occurs, it can result in symptoms ranging from thirst and dry mouth to more severe complications such as dizziness, confusion, or even organ failure in extreme cases. Recognizing and addressing dehydration promptly is crucial, especially in settings where individuals may be exposed to heat or have increased physical demands, such as military operations.
