What can be a sign of dehydration during athletic activities?

Dark urine and extreme thirst are significant indicators of dehydration during athletic activities. When the body is properly hydrated, urine typically appears light yellow or clear; a darker color suggests that the body is conserving water due to insufficient fluid intake. Extreme thirst is a physiological response that prompts an athlete to seek hydration when the body's water levels are low. Recognizing these signs is crucial because dehydration can impair performance, increase the risk of heat-related illnesses, and negatively affect overall health. This awareness allows athletes and coaches to take preventive measures, ensuring optimal hydration before, during, and after exercise.
