Hypohydration

Meaning

Hypohydration is the clinical state of total body water deficit, specifically a negative water balance resulting from inadequate fluid intake or excessive fluid loss, which exceeds the body’s physiological compensatory mechanisms. This condition is distinct from simple thirst; it represents a measurable reduction in body water content that can compromise systemic function, including the precise regulation of the endocrine system. Even mild hypohydration can impair cognitive function, thermoregulation, and hormonal signaling clarity, negatively impacting overall wellness and performance. Maintaining euvolemia is a critical component of metabolic health.
