How does dehydration affect athletic performance?

Dehydration significantly impacts athletic performance by impairing various physiological functions essential for optimal performance. When an athlete is dehydrated, the body's ability to regulate temperature is compromised, leading to an increased risk of overheating. This can result in fatigue, decreased stamina, and a decline in strength during physical activity.

Additionally, dehydration affects cardiovascular function. With decreased fluid levels, the heart must work harder to pump blood, leading to an increased heart rate and ultimately reducing exercise efficiency. Mental processes, including focus and coordination, can also be negatively affected by dehydration, which can further compromise an athlete's overall performance.

Maintaining proper hydration is crucial for athletes to sustain endurance, strength, and cognitive function during competition or training. Therefore, the impact of dehydration clearly demonstrates that it can decrease performance.
