What is a common symptom of dehydration in athletes?

Fatigue and dizziness are well-documented symptoms of dehydration in athletes. When the body loses more fluids than it takes in, it disrupts the balance necessary for optimal physical performance. Dehydration can lead to decreased blood volume, which means less oxygen is delivered to the muscles, resulting in fatigue. Dizziness can occur due to reduced blood flow to the brain and changes in electrolyte levels, which can affect coordination and mental clarity. Recognizing these symptoms is crucial for athletes, as dehydration can severely impair their performance and increase the risk of heat-related illnesses. Maintaining proper hydration is vital for sustaining energy levels and overall athletic performance.
