Performance of improving immunity

The recovery speed of daily minor ailments is significantly faster, the seasonal changes/high incidence of influenza are rare, and the persistent light fatigue can be quickly eliminated. There is no need to look up complex immune cell counts. These actual feelings in life are more meaningful than the small fluctuations in the test sheet.

Don't believe it, last year I helped an Internet operator adjust her diet. She used to have oral ulcers once a month, which took 10 days to heal. Her tonsils became inflamed after staying up late, and she had to prepare anti-inflammatory drugs in advance even when she ate spicy food. After 3 months of treatment, she came to me for review last week and said that the two ulcers caused by eating hot pot a few days ago disappeared on their own in 3 days, and she didn't even open the watermelon cream she kept in her bag all year round. Interestingly, modern medicine and traditional Chinese medicine have completely different logics in explaining this performance, but they have the same conclusion: evidence-based medicine believes that this is an increase in the level of immunoglobulin A secreted by the oral mucosa, which speeds up the removal of pathogens. ； My friend who is a Chinese medicine practitioner said that this is because the healthy Qi of the spleen and stomach has been replenished, and the deficient fire will not rise easily. The essence is that the body's defense ability is getting stronger.

At this point, some people may ask, does not having a cold or fever all year round count as a good immune system? In fact, there have been two different voices in the industry on this issue: one group believes that being free from minor illnesses all year round is indeed a sign of stable immune defense function, indicating that the body can clear pathogens at their early stage of invasion without triggering an obvious inflammatory response. ； But the other group will also remind that not triggering an immune response for a long time may actually reduce the "alertness" of immune cells. Clinically, there are indeed many patients who don't even seem to catch a cold, but a more serious problem is found upon inspection, so there is no need to regard "never getting sick" as the only gold standard.

What particularly impressed me was the flu in the office last winter. People on half the floor had fevers above 38 degrees. The girl sitting next to me wore an ordinary medical mask and walked through the crowds of coughing people every day, but nothing happened. In the past, she would suffer from allergic rhinitis every autumn. She would sneeze for half a month and her eyes would be swollen like walnuts. When asked what she had done, she said she had not taken any expensive supplements in the past six months. She just went to the park to run 3 kilometers three nights a week and went to bed before twelve o'clock. It was as simple as that. There have long been relevant studies in the field of exercise immunology. Regular moderate-intensity exercise can increase the activity of immune cells in peripheral blood by about 30%. However, there is no need to blindly engage in high-intensity training. On the contrary, overtraining will temporarily suppress immunity, which is not worth the gain.

Another sign that is easily overlooked is that recovery speed becomes faster after being tired. Many people must have had this experience before: staying up all night for a week or going out for two days to play wildly. After coming back, I feel sore and lazy, and I don't even want to cook. It takes two or three days to recover. If you find that this situation has disappeared recently, and even if you stay up late and are very tired, you can still be energetic and energetic when you wake up the next day, then it is most likely a sign of improved immunity. To put it bluntly, immune cells help you quickly clean up the inflammatory factors produced by the body's metabolism. Previously, these things accumulated in the body and would make you feel tired. I used to run a half marathon, and my legs would hurt for two days after running. After exercising regularly for more than half a year, I ran 10 kilometers last week, and went hiking with my friends the next day. I was not affected at all. This kind of real body feeling cannot be deceived.

Oh, by the way, don’t believe those statements on the Internet that “more crescents means good immunity” and “a rosy face means strong immunity”. These have no clear scientific basis - the number of crescents is essentially related to the growth rate of the nails. Some people are born with fewer crescents, which does not mean that they are in poor health. There are also many people who hope to quickly improve their immunity by taking imported supplements. This is not recommended by either modern medicine or traditional Chinese medicine: only people who are clearly deficient in nutrients such as vitamin D and zinc will see significant improvements after supplementation. Ordinary people only need to eat a balanced diet, and extra supplements will mostly cost IQ tax. Traditional Chinese medicine also often says that "deficiency cannot be supplemented." Indiscriminate supplementation will easily add extra burden to the body.

In fact, to put it bluntly, immunity is a very "honest" thing. How you treat your body will reflect back to you. There is no need to worry about whether your immunity is sufficient every day. Pay more attention to your daily status, which is more reliable than any fancy test. I really feel that I get tired easily and get sick very often recently. I need to get enough sleep, eat well, and take some time to move every week. It will be more effective than any expensive supplements.
