Healthy Body, Healthy Mind

We all know exercise is important, yet we don’t always want to do it! Often we are too busy or feel lazy. But we should try our best to exercise every day.

Exercise is good for our body. When we exercise, our body changes. Exercise develops our muscles and makes us stronger. When we exercise, we use energy. This keeps our weight down. Being overweight puts stress on our body. It can cause pain in our back and knees, and even cause more serious problems such as heart disease later in life.

Exercise is also great for our brain. During exercise, our heart beats faster and we breathe harder. Our brain gets more oxygen because of this, and that helps our memory improve. Scientists also tell us the body makes more of certain chemicals after exercise. This helps us to learn and think well. So, when you have trouble with your homework, do some exercise, then try again!

Exercise also helps us to feel happier. When we exercise, our brain makes special chemicals. These chemicals can relax our body and calm our mind. Feeling fit can also make us feel better and more confident about ourselves. When we play a sport with others, we can even make new friends.

Remember: Health is wealth. The more you exercise, the healthier you become. Try to make exercise a part of your life.
