Environmental pollutants can significantly impact fitness levels by affecting both physical health and exercise performance. Exposure to pollutants like particulate matter and ozone may lead to respiratory issues, reduced lung function, and lower overall endurance. Furthermore, individuals living in heavily polluted areas may experience higher rates of health problems such as asthma and cardiovascular diseases, making physical activities more challenging. Addressing environmental quality is vital for promoting public health and encouraging outdoor physical activities, ultimately fostering a healthier, more active lifestyle.
