For the four cornerstones of adolescent students' health, we can divide them into specific reasons: why, how often, what is good and what is sound.

Four cornerstones of adolescent students' health:

1, to get healthy, we should have a reasonable diet.

A reasonable diet refers to a balanced and nutritious diet. A variety of foods can meet the various nutritional needs of the human body and achieve the purpose of improving health. However, if we only choose food according to personal tastes and hobbies, we will eat more if we like it, and eat less if we don't like it, which may not only lead to unbalanced nutrition, but also lead to malnutrition sometimes. Therefore, we should learn to eat reasonably and develop good eating habits.

2. Do moderate exercise.

Moderate exercise means that the way and amount of exercise are suitable for your physical condition and you can persist in exercise. Middle school students should insist on physical exercise for one hour every day, which is not only the requirement of the state for middle school students, but also the need of their physical and mental development and physical education and health course learning. Therefore, it is a healthy lifestyle to arrange the time of study and physical exercise reasonably and exercise moderately.

3. lead a regular life.

Regular life refers to regular work and rest, including regular diet, regular study and various activities to ensure adequate sleep. Middle school students usually sleep 8-9 hours every day.

A regular life is the premise to ensure health and promote growth and development, and it is also one of the important conditions to promote the intellectual development of middle school students and achieve good academic performance. Whether attending classes on an empty stomach, lack of sleep or irregular learning activities will not only disrupt students' lives, but also make them physically tired, mentally exhausted and their academic performance decline. So junior high school students must live a regular life.

4. Achieve psychological balance.

Psychological balance is a good psychological state. For teenagers, being able to know themselves and their peers correctly, learning to accept themselves and new friends, being good at communicating with others and keeping a happy mood are the basis for maintaining mental health. At present, according to the modern concept of health, health is no longer the absence of disease in the body, but mental health is an important part of health.

As a middle school student, facing the setbacks and difficulties in daily study and life, I can face up to myself, cheer for my classmates' progress with a good attitude and actively communicate with others. This not only gains a happy mood, but also forms a good psychological quality.
