How to Keep Healthy

It’s important for us to keep healthy. As a middle school student, we should have a healthy lifestyle. Here are some suggestions.

First, we should do exercise at least one hour a day, such as running or walking. Second, have a healthy diet. Eat more fruit and vegetables. Try not to eat junk food. Third, we’d better not to spend too much time going online. It is bad for our study and eyes. Fourth, go to bed early and don’t stay up too late because enough sleeping is good for our health. Finally, be happy as possible as we can. Learn to smile at any time.

If we can do what is listed above, I believe we can keep healthy.
