What does acclimatization refer to in the context of exercise?

Acclimatization in the context of exercise refers to the process through which the body gradually adjusts to changes in the external environment, such as temperature, humidity, and altitude. This adjustment period is important for athletes and individuals engaging in physical activity, as it helps improve performance and reduce the risk of heat-related illnesses when transitioning to different climates or conditions.

When individuals acclimatize, their bodies can develop better thermoregulation, enhanced sweat response, and improved cardiovascular efficiency, which are essential for maintaining performance and safety during exercise in challenging environmental conditions. For example, when an athlete moves to a hotter climate, their body will gradually adapt to manage higher levels of heat stress, allowing them to exercise effectively and safely.
