It is important for us to keep healthy. We should exercise every day. After school, I often run and play basketball with my father.
We should also leave the bedroom window open. We shouldn't keep the window closed. The air in the room should be kept fresh and clean. We must wash our hands, especially before meals. Drink more water every day. Don't spit everywhere. When we are tired, we should not work too late at night. We should go to bed early.
In order to be healthy, we should keep a balanced diet. We'd better eat less junk food. It is best to drink milk and eat fruit every day.
I hope it will be useful to you from the aspects of exercise, hygiene and diet.
