Environmental toxins can significantly affect health and fitness by increasing the risk of chronic diseases, impairing respiratory function, and disrupting hormonal balance. Exposure to these toxins, found in polluted air, contaminated water, and certain chemicals, can lead to inflammation and decreased energy levels. This may reduce overall physical performance and inhibit one's ability to exercise regularly. Moreover, toxins can accumulate over time, affecting long-term health outcomes and potentially leading to conditions such as obesity, diabetes, and cardiovascular diseases, which ultimately impact an individual's ability to maintain an active lifestyle.
