Which of the following is a common sign of dehydration in athletes?

Dry mouth and fatigue are common signs of dehydration in athletes because dehydration can lead to a significant decrease in fluid levels within the body, impacting overall performance and well-being. As athletes engage in physical activity, they lose fluids through sweat, and if those fluids are not adequately replaced, they may experience symptoms such as dry mouth, which is a direct result of reduced saliva production, and fatigue, as the body's energy levels can drop when it's lacking sufficient hydration.

Maintaining proper hydration is vital for optimal athletic performance. Signs of dehydration can vary, but dry mouth and fatigue are among the first indicators athletes may notice, signaling the need for increased fluid intake. Recognizing these symptoms early can help athletes take corrective action, reducing the risk of severe dehydration and its associated complications.
