It is important to keep healthy. Having good habits is helpful for achieving this goal. What are good habits? For example, exercising three times a week is a good habit. Getting enough sleep is another. It is good for us to go to bed and get up early. It is also helpful to drink a lot of water and eat healthy food such as fresh fruit and vegetables. Never eat too much. More importantly, eating junk food will make you fat and even sick.
Mental health is as important as physical health. If you feel sad, talk to your parents or teachers. Besides, you can play sports with friends or go dancing on the weekend. Try to do things that you like when you are in a bad mood. To sum up, we should take good care of our body and mind because keeping healthy is the secret to a happy life.
