mentions the three words "" and "immunity" " and everyone is familiar with it. Simply put, immunity can play an effect of blocking external bacteria. When the body is infected with bacterial immune system, it will also mobilize a large number of cells to fight against the virus desperately, so as to prevent health damage.
Not only that, immunity can also detect cancer cells. Once the cells are found to be malignant, they will produce corresponding cells to eliminate them. However, if the immunity gradually decreases, there will be minor problems such as colds and fevers, and in severe cases, it will even lead to malignant tumors.
So immunity is the basis of physical health. Once "lost", lifespan will inevitably be affected by . , especially the symptoms mentioned below, are warning us that we have decreased immunity.

1. It is easy to get sleepy
sleepy is a situation that everyone will encounter, but most of them will only occur when the sleep time is not enough, and it can improve or disappear after rest.
may have enough sleep time recently but still have symptoms of sleepiness. At the same time, accompanied by weak and weak body, you should go to the hospital for examination in time;
If no disease is detected, it is likely to be a sign of decreased immunity. Please pay attention to supplementing nutrition and exercising more.

2. Colds are repeated and repeated
. Although many people have experienced it, they will not appear repeatedly. However, if the environment does not change much, they are troubled by the cold, and after various treatments, they cannot be completely cured.
Especially after getting up in the morning, you always have symptoms of sneezing and runny nose, which is actually closely related to low immunity.

3, gastrointestinal poor
When immunity decreases, the person's gastrointestinal function will also be affected. For example, the appetite has deteriorated in recent times. At the same time, after eating foods such as excessively cold, excessively acidic, and excessively spicy, symptoms such as gastrointestinal pain and diarrhea and vomiting will occur.

4, easy to be allergic

The key to maintaining human immunity is healthy and comprehensive dietary nutrition. It is reminded that everyone should try to diversify their diet, such as not only eating staple foods, but also eating more fresh fruits and vegetables;
Because these foods are rich in vitamins, minerals and trace elements , in addition, do not eat fixed foods for every meal to prevent unbalanced nutrition.

2, improve sleep quality
Research has found that ensuring sufficient sleep time can make the human body produce some sleep factors, thereby promoting the increase of white blood cells , and at the same time strengthening the liver's ability to decompose toxins, so as to better eliminate bacteria and viruses.
3. Multi-exercise
exercise is not only a way to burn fat, but also increases the number of immune cells , thereby improving immunity and preventing diseases.

In short, immunity is the basis for maintaining physical health. Only when immunity is at a high level can bacteria and viruses be eliminated and prevent them from causing trouble to the human body.
