What are common signs of dehydration?

Dehydration occurs when the body loses more fluids than it takes in, leading to an imbalance that can affect overall health and bodily functions. Common signs of dehydration include dry mouth, fatigue, and dizziness.

A dry mouth occurs because there is insufficient saliva production due to reduced fluid levels. Fatigue is a common symptom since dehydration leads to a decrease in blood volume, which in turn can reduce the body's ability to transport oxygen and nutrients, resulting in feelings of tiredness. Dizziness may arise because dehydration can cause a drop in blood pressure, affecting the brain's access to adequate blood flow and oxygen.

Recognizing these symptoms is crucial, particularly in marine environments where access to fresh water may be limited, and the physical demands can increase fluid loss. By identifying these signs early, appropriate measures can be taken to rehydrate and prevent further complications.
