Why are some people weak and sick when they are young, but strong and healthy when they grow up?

In fact, this is a normal physiological phenomenon, because when we were young, under normal circumstances, our resistance and immunity were relatively low, and some physiological organs of many children were not fully developed. At this time, our bodies are easily invaded by bacteria, which makes us weak and sick. When we grow up slowly, our bodies become stronger and stronger, and our immunity will gradually increase after our continuous strengthening the day after tomorrow, and then we will become stronger and stronger. In the process of growing up, we only need to pay attention to the following points, so that I can gradually become stronger:

1, exercise regularly

Exercise has many benefits. It can accelerate the blood circulation in our body, promote metabolism, improve the oxygen supply to muscles and brain, and make our body stronger slowly. I was a sickly person when I was a child, but I insisted on exercising every day after serving as a soldier. Up to now, I have become very strong.

2. Comprehensive nutrition.

It is also very important to supplement nutrition in an all-round way, because the lack of nutrition will make the resistance of some parts of our body low, which will affect our health in the long run, and comprehensive nutrition supplement will also make a weak and sick person get better slowly.

3. Keep a good sleep

Friends who are familiar with nutrition know that a good sleep is the foundation of a person's health. If a person does not have a good sleep, then many diseases will follow. So we don't have to worry about getting sick when we are young. First, keep a good sleep, adjust the balance between immunity and metabolism, and then gradually get better through exercise and nutrient intake.
