Climate affects exercise performance in various ways, including temperature, humidity, and altitude. High temperatures can lead to overheating and dehydration, impairing physical performance and increasing the risk of heat-related illnesses. Conversely, cold weather can cause muscle stiffness and impact endurance. Humidity levels influence sweat evaporation, affecting thermoregulation and comfort during physical activity. Additionally, training at high altitudes presents challenges, as reduced oxygen levels can lead to quicker fatigue. Adapting workout strategies to suit climatic conditions is essential for optimal performance and safety.
