How does dehydration affect exercise performance?

Dehydration significantly decreases performance and increases fatigue during exercise. When the body is not adequately hydrated, several physiological processes are compromised. Water is essential for regulating body temperature, maintaining blood volume, and facilitating the transport of nutrients and oxygen to muscles.

As dehydration progresses, the body struggles to cool down through sweating, which can lead to overheating and increased heart rate. This can result in a decline in stamina and endurance, making it more challenging for an individual to maintain the same level of intensity during physical activity. Furthermore, as dehydration sets in, the muscles may become more fatigued more quickly due to a lack of essential electrolytes and nutrients needed for muscle contraction and recovery.

This negative impact on exercise performance underscores the importance of proper hydration before, during, and after physical activity to ensure optimal physical performance and minimize the risk of fatigue and dehydration-related complications.
