Climate affects exercise choices and performance in various ways, such as temperature, humidity, and altitude. Hot and humid conditions can lead to increased risk of dehydration and heat-related illness, prompting individuals to modify workout intensity and duration. In contrast, cold weather may necessitate additional clothing and heat retention strategies. Altitude can impact oxygen availability, affecting endurance and overall performance. Therefore, individuals may need to adapt their exercise routines according to climate conditions, taking precautions to maintain safety and optimize performance while engaging in outdoor activities.
