With the approach of Senior 3, students, who are now in the second half of Senior 2, are under increasing great pressure, which has affected some students’ life, preventing them sleeping well and causing problems with their health. However, following the instructions below and sticking to them can ensure you a good health.

First, keep in mind that work is not all your life. Appropriate leisure time and entertainments should be part of it. Second, it is important to keep a healthy and balanced diet. Staying away from junk food and eating healthy food like vegetables and fish will benefit you. Third, enough and regular exercise is good to health, too. Running, swimming and ball games are all good forms of exercise.

Of course, good health means being both physically and mentally healthy. Keeping an optimistic state of mind will contribute to a good physical state.
