Define the term "dehydration."

Dehydration refers to a state in which the body loses more fluids than it takes in. This condition can occur when there is insufficient fluid intake, excessive sweating, illness, or diarrhea, among other factors. When the body is dehydrated, it does not have enough fluids to function properly, which can lead to a range of health issues, including thirst, dry skin, dizziness, and in severe cases, complications that may require medical intervention. Understanding this term is essential for recognizing the importance of maintaining a balanced intake of fluids for overall health. It is particularly crucial in contexts where physical activity levels are high or environmental conditions may lead to increased fluid loss. The other options describe scenarios that do not align with the definition of dehydration.
