What is a common sign of dehydration in swimmers?

A common sign of dehydration in swimmers is dark urine and dry mouth. When the body loses more fluids than it takes in, it can result in concentrated urine, which often appears darker than usual. Dry mouth occurs as the body lacks sufficient water to maintain moisture levels, making the mouth feel parched and uncomfortable.

Recognizing these signs is crucial for swimmers, as dehydration can significantly impact performance, increase the risk of heat-related illnesses, and lead to decreased coordination and focus in the water. Proper hydration not only allows for better physical performance but also lowers the chance of experiencing heat exhaustion or other serious conditions related to dehydration.
