Regular physical activity plays a crucial role in preventing chronic diseases such as heart disease, diabetes, and certain cancers. Exercise helps maintain a healthy weight, lowers blood pressure, and improves cholesterol levels. It also enhances insulin sensitivity, reducing the risk of type 2 diabetes. Furthermore, physical activity can support mental health by reducing symptoms of anxiety and depression, contributing to overall well-being. Engaging in at least 150 minutes of moderate-intensity exercise weekly is recommended for significant protective benefits against chronic illnesses.
