Final answer:
Regular physical activity can protect against multiple potentially deadly diseases, including diabetes, cardiovascular diseases, and certain types of cancer, by improving overall health and reducing risk factors associated with a sedentary lifestyle.
Step-by-step explanation:
Regular physical activity is known to protect against a variety of potentially deadly diseases. These diseases include diabetes, various forms of cardiovascular diseases, and certain types of cancer. Regular exercise has a considerable impact on health, contributing to the prevention of lifestyle diseases by improving the strength and efficiency of the muscular and cardiovascular systems.
It also aids in weight management, thereby reducing the risk of obesity, a common risk factor for many noninfectious diseases. By maintaining a healthy lifestyle that includes physical activity, individuals can reduce their risk of developing metabolic syndrome, which is a significant contributor to cardiovascular diseases and type 2 diabetes.
