Final answer:
Regular physical activity can protect against potentially deadly noncommunicable diseases like heart disease, Type 2 diabetes, and certain cancers, by improving cardiovascular health and muscular strength, and aiding in weight management. It does not protect against infectious diseases such as yellow fever. Adopting regular exercise can greatly reduce the risk of developing lifestyle-related diseases.
Step-by-step explanation:
Regular physical activity protects against a number of potentially deadly diseases, notably lifestyle-related noncommunicable diseases. These include respiratory diseases, heart disease, Type 2 diabetes, and certain types of cancer. Regular exercise enhances the health of the muscular system, leading to stronger and bigger muscles.
Furthermore, maintaining an active lifestyle can help reduce the risk of these diseases by improving cardiovascular health, increasing bone density, and aiding in weight management. It's also important to note that while physical activity can reduce the risk of many noncommunicable diseases, it does not protect against infectious diseases such as yellow fever.
Most of the chronic noninfectious diseases that cause a high number of deaths in developed countries, like heart disease, stroke, diabetes, and cancer, have lifestyle components that can be modified to decrease risk. Engaging in physical activities is one of the crucial behavioral changes that can reduce the likelihood of developing these diseases. Moreover, an estimated 80 percent of cardiovascular diseases and type 2 diabetes cases, along with 40 percent of cancer cases, could potentially be prevented with lifestyle changes, illustrating the significant impact of exercise.
By choosing to be physically active regularly, avoiding foods high in fats, and keeping a healthy weight, one can prevent the development of diseases like type 2 diabetes, especially for individuals with a family history of the disease. The benefits of exercise extend well beyond disease prevention, contributing to improved overall health, fitness, cognitive function, and emotional well-being.
