Performance of improving immunity

Respiratory or allergic ailments are less likely to occur frequently during the change of seasons. Trauma heals significantly faster and is less susceptible to infection. The body's recovery speed after short-term overdraft is significantly improved. The remaining so-called "beautiful complexion" and "increased appetite" are mostly incidental effects and cannot be considered as the core judgment criteria.

I have a friend who used to be a typical "seasonal disease". Every spring, he would suffer from hives and cough for half a month in autumn. Last year, he started following a nutritionist to adjust his diet and exercise regularly. This spring, he didn't even take anti-allergic drugs during the half-month period when catkins were floating around. He only occasionally itched his arms twice, but he didn't even get a rash. Of course, some allergist doctors will say that this situation may also be due to immune tolerance formed by long-term low-dose exposure to allergens, which is not the same thing as the improvement of overall immunity. This is indeed true, but if he also escaped two rounds of influenza in his workplace this spring, and his throat was just a little dry when his colleagues around him had a fever of 39 degrees, then it can basically be confirmed that the concentration of immunoglobulin G in the body has reached the standard, and the early warning speed of immune cells is more than a little faster than before.

Speaking of which, when I was volunteering at a community health center, I also discovered an interesting pattern: For those elderly people who rarely get colds, urinary tract infections and other infectious diseases within half a year, the average bruises caused by daily rubbing will disappear 2-3 days faster than other elderly people, and the small cuts made when cutting vegetables rarely appear red, swollen and pus. Of course, some people will say that fast wound healing is mainly due to good coagulation function and has nothing to do with immunity. This statement is half right - coagulation function determines how quickly you scab, but whether it will become inflamed and whether it will leave ugly red marks all depends on whether neutrophils and macrophages can arrive at the wound in time and eat the invading bacteria. This in itself is one of the core manifestations of immunity. After I had my penis last year, it took a week for the small incision to heal, and it still became red and swollen. Now when I cut my finger while cutting vegetables, I put a band-aid on it and it healed in two days without even leaving a mark. The difference is really obvious.

There is another point that many people ignore, which is the resilience after short-term overdraft. For example, I used to stay up late at night to catch up on projects, and I had to slow down for two or three days before I could regain my consciousness. I felt tired even after taking two steps. Now I occasionally work overtime until 12 o'clock, and sleep on the table for 20 minutes at noon the next day. I am still energetic in the afternoon and will not feel groggy all day. In fact, your immune cells are like a cleaning team in your body. In the past, there were not enough manpower, and the damaged cells and metabolic waste created by you staying up all night would take three days to be cleared away. Now the team's combat effectiveness has increased, and they can clean everything for you overnight, so you will naturally not feel tired the next day. Of course, some nutritionists have suggested that this situation may be due to the fact that you have recently taken enough B vitamins and protein, and it is not necessarily an improvement in immunity. Indeed, adequate nutrition is the basis for improvement of immunity, but if you meet the first two symptoms at the same time, then your immunity has really improved to a higher level, no doubt about it.

Of course, there are also many so-called "immunity-boosting manifestations" that are actually misunderstandings. For example, many people believe that long-term absence of fever means good immunity. There is no unified conclusion in the academic circles on this issue: one group believes that the long-term absence of fever indicates that the immune monitoring system is sensitive enough, and the pathogens are eliminated as soon as they invade, without any chance to trigger the response of the thermoregulatory center; the other group believes that the absence of fever and other immune responses for too long may indicate that the immune cells are not sensitive enough, and it is prone to severe illness when encountering virulent strains. So there is no need to be anxious or complacent about "I haven't had a fever in three years." Individual differences are huge, so there is no need to set rigid standards. Other things like "better appetite" and "rosy complexion" are even less likely. Recently, I have been exercising a lot and I am in a good mood. These effects may have occurred, but it doesn't count.

In fact, after all, immunity is really not what it is advertised in health product advertisements. It can only be achieved by relying on sky-high-priced supplements. My own feeling is that you don’t need to do any fancy immune function tests. If you pay more attention to these small reactions of your body, you can basically understand your immune status. After all, our own bodies are always more honest than cold detection values, right?
