What is NOT a consequence of dehydration?

Improved athletic performance is not a consequence of dehydration because adequate hydration is essential for optimal physical function. When the body is dehydrated, it cannot perform at its best; hydration is crucial for regulating body temperature, maintaining blood circulation, and ensuring that muscles and joints function properly. Dehydration often leads to negative effects such as impaired endurance, decreased strength, and increased fatigue, which can hinder athletic performance.

In contrast, dry mouth, increased body temperature, and fatigue are well-established consequences of dehydration. Dry mouth occurs because the body lacks sufficient fluids to produce saliva. Increased body temperature arises as the body's mechanisms to cool itself become less effective without adequate fluid levels. Fatigue is a common symptom linked to dehydration, as the lack of fluids can affect energy levels, cognitive function, and overall physical endurance.
