Dehydration occurs when the body loses more fluids than it consumes, impairing its ability to function effectively. During exercise, dehydration can lead to a significant decline in performance due to decreased blood volume, reduced sweat production, and impaired thermoregulation. Symptoms may include fatigue, dizziness, and muscle cramps, all of which can severely hinder exercise outcomes. Adequate hydration is essential for maintaining energy levels, ensuring optimal cognitive function, and supporting recovery. Thus, staying hydrated is vital for enhancing and maintaining exercise performance.
