What is a potential negative effect of excessive caffeine consumption?

Excessive caffeine consumption can lead to increased dehydration due to its diuretic properties. Caffeine stimulates the kidneys to excrete more sodium and water, which can result in a loss of fluids. This effect can be particularly concerning in athletes who already need to maintain proper hydration for optimal performance and recovery. While moderate caffeine intake may offer benefits like improved focus and energy levels, when consumed in excess, it can hinder overall hydration status, potentially impacting physical performance and recovery processes. This understanding is crucial for athletes and individuals engaged in sports medicine, as maintaining hydration is essential for maintaining health and enhancing physical activity.
