Environmental factors, such as temperature, humidity, and air quality, can significantly influence workout performance. For instance, extreme heat can lead to quicker exhaustion and dehydration, while cold weather may result in decreased flexibility and muscle stiffness. High humidity levels can exacerbate the perception of exertion, making workouts feel more strenuous. Additionally, poor air quality can affect lung function and endurance. Understanding these factors can help individuals adapt their workouts or choose optimal environments, ensuring more effective and pleasurable exercise experiences.
