The normal performance of sub-health is that you have poor sleep quality at night, insomnia and dreaminess, and then go to work during the day, and your skin is in poor condition. You often feel weak all over, and sometimes your heart beats violently, but it will get better after a while. This is the performance of sub-health. Sub-health is also reflected in other aspects. For example, your physical strength will be worse than before, and you feel that your thinking efficiency at work is much worse than before, which proves that your body is gradually out of order. If something goes wrong, it must be treated, but it is not a unique disease in itself, and it is difficult to treat it by medical means.
If you improve your immunity, you can gradually eliminate the sub-health state. Exercise is the simplest and most effective way to improve the body's immunity, which is suitable for people of all ages. You have to run for about half an hour every day. If you persist for a month or so, we will find that your health is much better than before. Don't think that setting aside half an hour every day is a waste of time. On the contrary, it makes your time more abundant. This will only make thinking more efficient. What was done in the past three hours can now be done in two hours. This is an effective use of time and is good for your health. If you persist for a long time, you can maintain more vigorous energy to work and study.
If you often feel some of the above symptoms, and then in the season of changing seasons, others are not sick, and you are sick, it means that your own immune ability is too low, and you are a little sub-healthy. You still have to exercise, even if you delay your work and study, it will help your health. After all, you can only work and study for a long time if you have a healthy body. Many things are a continuous process, and it is not enough for you to work hard for two days.
