Which symptom is NOT associated with early dehydration?

The correct answer is based on the understanding of how the body reacts to early dehydration. Early symptoms of dehydration typically include excessive thirst, dizziness, and a dry mouth, which are all signals that the body is beginning to experience a fluid deficit.

A normal heart rate, however, is not a symptom associated with early dehydration. In fact, as dehydration progresses, the heart rate often increases in an attempt to maintain adequate blood flow and deliver oxygen to vital organs despite lower blood volume. Therefore, if the heart rate is normal, it suggests that the body is still able to maintain its circulatory function effectively, which is not typically the case in early dehydration. Recognizing these symptoms is essential for identifying dehydration and taking appropriate measures to rehydrate.
