Which of the following is a benefit of regular physical activity?

Regular physical activity contributes significantly to improved overall well-being. Engaging in consistent exercise has been well-documented to enhance physical health by reducing the risk of chronic diseases such as heart disease, diabetes, and obesity. Additionally, it promotes mental health by alleviating feelings of depression and anxiety, leading to better mood and emotional stability.

Physical activity also fosters social interactions and provides a sense of community, which can further enhance emotional well-being. The physiological benefits, such as improved cardiovascular function, increased stamina, and better muscle strength, contribute to a higher quality of life and greater longevity.

In contrast, the other options indicate negative effects that are contrary to the established benefits of regular physical activity. For instance, an increased risk of chronic diseases and decreased mental health are not aligned with the known positive impacts of exercise. Similarly, heightened stress levels are often mitigated, rather than exacerbated, through regular physical activity.
