What is needed to improve immunity

Improving immunity is never achieved by relying on a certain "magic" supplement. The essence is to keep the body's immune regulatory system in a dynamic and steady state - it will neither underreact and let pathogens come in to cause trouble, nor will it overreact and attack its own healthy tissues.

Many of my friends go crazy and stock up on vitamin C effervescent tablets, imported immune gummies, and various mycelium supplements as soon as the seasons change. They treat these as "immune talismans" and eat them every day. There was a girl who worked in operations before who was even more exaggerated. She had half a drawer filled with supplements in her office drawer. As a result, her physical examination last year showed high uric acid. When I asked her, I found out that several of the supplements she took had added fructose, and her daily intake had already exceeded the amount. As for whether supplements can improve immunity, the academic community has always had different views: one group believes that as long as the daily diet is balanced, the protein, vitamins, and trace elements needed by the human body can be obtained from food. Extra supplements are not only useless, but also increase the metabolic burden of the liver and kidneys. Some people who have long-term high-dose vitamin C supplements have even experienced symptoms after suddenly stopping taking them. Another school of thought believes that for patients recovering from surgery, people with a BMI below 18.5 who have been dieting for a long time, or office workers with a seriously unbalanced daily diet, proper supplementation of multivitamins and protein powder as directed by the doctor can indeed provide sufficient raw materials for the synthesis of immune cells and help the immune system return to normal state as soon as possible.

After talking about supplements, we must also talk about the details of life that are most easily overlooked. After all, if you stay up until two or three o'clock every day, no matter how many supplements you take, you can't fill the hole created by staying up late. When I was following up with a teacher in the nutrition department, I met a young man who only slept 3 or 4 hours a day for a month in order to catch up on a project. He was as strong as a calf, but he caught a cold and developed pneumonia, and he was hospitalized for almost a week. In fact, most of the repair and renewal of immune cells are completed during deep sleep. Staying up late every day is equivalent to forcing the immune cells to spin continuously, which will definitely not be able to withstand it for a long time. Sitting for a long time is also an "immune killer" that many people don't pay attention to. Lymphocytes are supposed to follow the blood circulation and patrol the whole body to look for pathogens. If you sit for eight or nine hours, the blood flow slows down, just like the patrol police are blocked on the road, and there is no way to get there immediately if a virus invades.

There is also a popular saying recently that "moderate exposure to cold can improve immunity." Supporters have reported that short-term cold exposure can activate brown fat and increase the activity of immune cells. Indeed, there are many people who insist on winter swimming all year round and rarely catch a cold; but the opposition is also very clear. I have asthma. , chronic obstructive pulmonary disease and other basic respiratory diseases, or people who are usually weak and afraid of cold, a sudden cold will weaken the defense ability of the respiratory mucosa and easily induce infection. To put it bluntly, this method is prepared for people with a foundation of exercise. If you usually get out of breath after walking two steps, don't just join in the excitement of "autumn freeze".

To put it bluntly, immunity is like a little guard you raise. You feed it enough eggs, milk, fresh fruits and vegetables and other serious foods every day, take it for a walk every day, and let it rest when the time is right.
