What are the manifestations of improving immunity?

The core performance of improving immunity is not "never getting sick again" as everyone thinks, but the body's response and recovery speed to external pathogens and injuries are significantly faster. Many times you don't even notice that you have been "sick", and the discomfort has gone away.

I used to have a friend who was an Internet operator. He would suffer from bronchitis during the change of seasons in the past two years. It was common for him to cough for half a month every time. When it was severe, he had to go to the hospital to hang up the water to suppress it. After the spring of last year, he forced himself to run 3 kilometers around the community three days a week at night. When ordering takeout, he would also add a side of hot vegetables to cool down. Seven or eight people had colds and fevers one after another. One day when he got off work, he felt that his throat was a little tight, so he went home and drank two large glasses of warm salt water and went to bed early. When he woke up the next day, nothing happened. This was a typical example of immunity coming up - it was not that he was not exposed to the virus, but that the immune system directly cleaned up the pathogens without waiting for them to multiply and cause chaos in the respiratory tract.

In fact, it can be seen in the small details of daily life. In the past, I always felt that my body was heavy after sleeping for eight hours. Herpes immediately appeared on the corner of my mouth after eating something spicy. A small cut on my hand did not scab for three days. These small problems gradually become less and less. In fact, it is also related to the improvement of immunity. After all, the immune system does not have to deal with all kinds of "little troubles" that leak in all day long. The body's energy can naturally be allocated to daily operations, and the whole person's state will be much relaxed.

There are quite a lot of controversies about this matter on the Internet. Some people say that not catching a cold once a year means that the immunity is full. Others say that never having a fever means that the immunity is slow and there is no early warning. Both of these opinions are actually too extreme. When I accompanied a friend to the infectious disease department for consultation, I specifically asked the doctor. The doctor said that as long as you come into contact with the source of infection, you will not get infected easily. Even if you are infected, the duration of the disease is shorter than that of others around you, and it will not develop into serious complications such as pneumonia and myocarditis every time. Regardless of whether you have a fever or how many colds a year, it shows that your immunity is normal. On the contrary, if you don't get sick all year round, you will become seriously ill, or if you develop allergies, hives, or inflammation everywhere at the slightest sign of trouble, these are signs of immune imbalance.

To use an inappropriate analogy, your immune system is like the security team of a community. In the past, the team members were all inactive. A thief sneaked in and stole something for several days before you discovered it, and you had to call the police outside (with medicine and injections) to help clean up the mess. Now that the team is well-trained, the thief will be pressed down as soon as he approaches the door of the community. Naturally, you will not suffer any big losses. At most, there will be a small commotion at the door, and you don't even take it to heart.

However, don’t rely on your immunity for all the benefits. If you have been having a chaotic schedule recently and still feel extremely energetic, or even have a low-grade fever from time to time, it may be a sign of hyperimmunity. Don’t blindly take health care products to improve your immunity. It is better to go to the hospital to check the indicators first, which is more reliable.
