What is a common symptom of dehydration?

Fatigue is indeed a common symptom of dehydration. When the body lacks adequate water, it can lead to a decrease in blood volume, which may result in the heart and muscles working harder to function properly. This increased effort can manifest as a feeling of tiredness or fatigue. Additionally, dehydration can disturb the balance of electrolytes in the body, further contributing to a general sense of lethargy and exhaustion. Recognizing fatigue as a symptom can help individuals take prompt action to rehydrate and restore balance in their systems, avoiding more severe complications.
