Final answer:
Physical activity leads to improved cardiovascular health, lowers the risk of chronic diseases, and has mental health benefits like reducing depression and anxiety.
Step-by-step explanation:
Physical exercise has numerous positive effects on the human body, which counters the options suggesting increased risk of chronic diseases, weakened immune systems, and slower metabolism. The correct answer to this question is that physical exercise leads to improved cardiovascular health. Through regular physical activity, individuals can reduce the risk of chronic diseases such as cardiovascular disease, some types of cancer, type 2 diabetes, and obesity. Regular exercise strengthens the cardiovascular system, improves muscular fitness, increases bone density, and fosters weight management.
Additionally, physical activity is associated with increased cognitive function and might offer protection from dementia and other cognitive problems. Exercise has also been linked to improved mental health by reducing symptoms of depression and anxiety, enhancing body image, and promoting positive self-esteem. Regular exercise, even as little as 30 minutes of noncontinuous exercise throughout the day, significantly lowers the risk of heart attacks and has notable long-term benefits on health and longevity.
