What is a common symptom of dehydration in athletes?

• A. Increased energy
• B. Dry mouth and fatigue
• C. Improved concentration
• D. Lower heart rate

Answer: (B)

Dry mouth and fatigue are common symptoms of dehydration in athletes due to the body’s reduced fluid levels impacting various physiological functions. When fluid intake is inadequate, the body struggles to maintain optimal hydration, leading to a marked decrease in performance and overall well-being.

Dry mouth results from decreased saliva production as the body prioritizes water retention. Fatigue occurs as dehydration can hurt muscle function, endurance, and energy levels, making it more challenging for athletes to perform effectively. This can also lead to other systemic issues, such as impaired thermoregulation and increased perceived effort during exercise.

Understanding these symptoms is crucial for athletes and trainers, as recognizing dehydration can help in implementing timely interventions to restore hydration and improve performance.
