What is needed to improve immunity

To put it bluntly, it is not something you can just rely on a certain Internet celebrity supplement or folk remedy. The essence is the dynamic balance of your entire life. Many people even don’t realize that “not messing with immunity” is much more useful than spending a lot of money to buy a bunch of supplements.

The most heated debate on the Internet right now is whether or not we should take additional supplements. One group says that as long as the daily diet has a reasonable mix of meat, eggs, milk, fruits and vegetables, it can fully cover the nutrients needed for immunity. Eating more is a waste.； The other group believes that nine out of ten young people nowadays eat irregularly and only eat takeout. There is nothing wrong with taking appropriate supplements of vitamin C, zinc, and vitamin D. Last year, I asked the nutritionist at the community hospital for my cousin who worked overtime until early in the morning every day. During that time, she ate takeout for half a month and developed herpes on the corners of her mouth repeatedly. After the serum vitamin level was checked, it was indeed low. She took 100 mg of vitamin C every day as prescribed by the doctor, and it disappeared in a week. , but the aunt downstairs in my house eats vitamin C like orange candy, and she wants to eat more than a dozen tablets every day. The last physical examination revealed mild kidney stones. The doctor said that it is most likely related to excessive vitamin C supplementation. To put it bluntly, whether to supplement and how much to supplement depends on your own dietary status, and you cannot just follow the trend and eat blindly.

Besides food, the most neglected things are actually sleep and mood. To be honest, I didn’t believe this before. Until a friend who I trained with in the gym last year was preparing for a competition. He only slept for more than 4 hours a day for a week. He ate protein and carbohydrates to the gram and didn’t miss any strength training. As a result, the day he cooled down. After going out for ten minutes, the wind blew and the temperature reached 38.5°C. Later, he read popular science and learned that most of the body's immune cells and antibodies are synthesized and repaired during deep sleep. Staying up late is equivalent to cutting off half of the immune system's logistical supply line. No matter how much nutrition you take, you can't fill the hole. Also, my best friend took the postgraduate entrance examination last year. She was so anxious that she cried every day for half a month before the exam. She eventually developed herpes zoster, which was so painful that she couldn't even hold a pen. The doctor said that it was due to long-term stress and high cortisol, which suppressed the immune function and allowed the chickenpox virus lurking in the nerves to come out and cause chaos.

As for whether exercise can improve immunity, the current opinions are not completely unanimous. Some people think that the higher the intensity of exercise, the better the immunity. Some sports medicine studies have confirmed that the 3 to 72 hours after a single high-intensity exercise is the "immune window period". During this stage, the body is more susceptible to pathogens. Several friends around me who often run marathons say they catch a cold every time they finish a race. Now they try not to go to crowded crowded places before and after competitions. On the contrary, a eldest sister in my department goes to the park for a brisk walk for 40 minutes three nights a week, and occasionally dances in the square for half an hour with friends. She didn't even catch a small cold a few times last year.

I also have friends who followed the trend and took immunoglobulins and drank so-called immune-enhancing enzymes. They spent a lot of money. Two people even went to the emergency room because of allergies to immunoglobulins. In fact, normal people’s immune systems have their own regulatory capabilities. You don’t have to think about prescribing it every day, just eat normally and sleep as much as possible7 Hours, less useless anxiety, moderate exercise and don’t overdo it, any supplement is more effective than any other supplement. To put it bluntly, immunity is like the green radish you keep on the balcony. Don’t water and fertilize it every day, and don’t leave it in the corner. Occasionally expose it to the sun and water it, and it will grow lush on its own. If you toss it too hard, it will easily cause root rot.
