Dehydration, or hypohydration, is defined as?

• A. Excess fluids in the body
• B. Not enough fluids for body processes
• C. Balanced fluids with electrolytes
• D. Varying fluid intake

Answer: (B)

Dehydration means the body doesn’t have enough fluids to support its normal functions. When fluid losses outpace intake, body water drops, which can raise blood osmolality and reduce circulating volume. This deficit is what hypohydration describes, so the idea of “not enough fluids for body processes” is the best fit. In practice, even mild dehydration can affect performance, thermoregulation, and heart rate during activity. The other options describe having too much fluid, having a balanced, proper amount with electrolytes, or simply inconsistent intake, none of which define dehydration.
