In our society today people are struggling from problems like obesity, coronary disease, and cardiovascular disease. Cardiovascular disease is the leading cause of death in the US, and had contributed to 729,000 deaths in 2009, which is almost double the amount of deaths caused by smoking. Many of these diseases occur due to physical inactivity and poor diet over periods of time. Diseases like for example obesity, begin developing in early stages of adolescent years, when children choose to eat unhealthy foods and lack in exercise. Physical education helps inculcate in children the importance of maintaining a healthy body and teaches then the importance of regular fitness activity in daily routine, which in return helps develop the knowledge, attitude, discipline, and confidence needed to maintain active lifestyles and acquire the skills needed to develop a positive attitude towards physical activity that will last a lifetime. Everyday physical activity and exercise can have dramatic health benefits in many ways. One way is it can help prevent excess weight gain or help maintain weight loss when combined with a diet. Exercise also reduces LDL cholesterol, increases HDL cholesterol and reduces blood pressure, which lowers the stress on your heart and lowers the risk of developing coronary heart disease. Physical activity not only benefits the physical aspect of our bodies but also the mental. Regular exercise can improve your mood and reduce the like hood of depression and anxiety. During physical activity our brain stimulates various chemicals such as endorphins that usually leave you feeling happier and more relaxed. This can help people build up their self-confidence and overall their state of wellness. Exercising daily can boost our energy level due to the cardiovascular system working more efficiently by circulating blood through your heart and blood vessels. Playing sports is another great way of maintaining a healthy lifestyle. Sports can help children develop healthy bones, stronger cardiovascular systems, motor skills, and powerful lungs. Children that are physically active in their early years are more likely to continue playing sports as an adult, promoting lifelong health. In conclusion, physical education, exercise/diet, and sport all play a big role in promoting health and the attainment of wellness.
