Under-hydrated
The state of having an insufficient amount of water in the body to maintain normal physiological function. This can result from inadequate fluid intake, excessive fluid loss (e.g., through sweating, vomiting, or diarrhea), or a combination of both. Symptoms range from mild thirst and dry mouth to more severe conditions like fatigue, headache, dizziness, and, in extreme cases, organ failure. The degree of under-hydration is often assessed by monitoring urine color, thirst, and in clinical settings, through blood tests. Chronic under-hydration can negatively impact cognitive function, physical performance, and overall health.
Under-hydrated meaning with examples
- Marathon runners are particularly susceptible to under-hydration due to extensive fluid loss through sweat. It is essential for them to consistently drink water and electrolyte solutions before, during, and after the race to prevent dehydration and maintain optimal performance. Proper hydration ensures their muscles function properly avoiding cramping and fatigue.
- During a heatwave, outdoor workers should be mindful of their fluid intake to avoid becoming under-hydrated. The constant exposure to high temperatures can lead to excessive sweating and a rapid depletion of body fluids. Regular breaks to rehydrate and stay in the shade are crucial for preventing heat-related illnesses.
- Children are more vulnerable to becoming under-hydrated than adults, especially during bouts of illness. Vomiting and diarrhea can quickly lead to fluid loss, necessitating careful monitoring of fluid intake. Parents and caregivers should offer frequent small drinks of water or an oral rehydration solution.
- The doctor advised the patient, complaining of persistent headaches and constipation, that they were likely under-hydrated and needed to increase their daily water consumption. She recommended carrying a water bottle and setting reminders to drink throughout the day to address the issue effectively.
