What is an essential guideline regarding caffeine and alcohol intake for athletes?

Athletes are advised to avoid alcohol and caffeine before events primarily due to the potential negative effects these substances can have on performance and hydration. Caffeine may lead to increased heart rate and potential anxiety, which could affect an athlete's focus and physical stability during competition. Additionally, while some athletes use caffeine strategically for its performance-enhancing effects in controlled doses, excessive intake before an event may lead to dehydration, particularly if not balanced with adequate fluid intake.

Alcohol, on the other hand, has a depressant effect and can impair coordination, balance, and reaction time—critical factors for athletic performance. Moreover, alcohol can lead to dehydration and negatively affect recovery. Therefore, it is essential for athletes to prioritize hydration and optimal physical condition leading up to an event, making avoidance of both caffeine and alcohol crucial for optimal performance.

Guidelines typically emphasize that athletes should prioritize their health and readiness by abstaining from substances that could impair their physiological capacity before competing.
