Why is it so critical for optimal cycling performance?

Be careful, though. You can get too warmed up. Normal body temperature is approximately 37 degrees C. If body temperature exceeds 40 degrees, a decrease in the efficiency of aerobic metabolism can occur since very extreme temperatures can inhibit enzyme activity (1,2). This emphasizes the need for good hydration and other cooling techniques during hot, humid conditions to maximize cycling performance.
