What are the signs of improving immunity

The most direct sign is that your response to external pathogenic factors becomes faster and your recovery time becomes shorter. It is not some mysterious "full of energy" or "invulnerable to all diseases".

When my immunity was weak in the past two years, I would catch a cold every time the season changed. It would last at least seven days at a time. I would have stomach upset for several days if I ate anything dirty. Even a mosquito bite would cause swelling for three or four days, and I would be so itchy that I couldn't sleep. For the past six months, I have insisted on sleeping 7 hours a day and playing badminton 2 days a week. The most obvious change is that last month at the company dinner, I had iced and spicy food. Three colleagues at the same table all went to the hospital for acute gastroenteritis. I had some acid reflux that night. I drank a cup of warm soda and it was fine. A while ago, several colleagues around me got the flu. I woke up with a tight throat in the morning. After drinking two cups of warm water, I felt nothing at all.

At this point, some people may want to mention the judgment standards mentioned on the Internet, such as "good sleep and high energy mean strong immunity." Some friends who are studying medicine have talked about this and said that this statement is actually a bit one-sided. Some people are born with energetic physiques, and it may be an abnormal state of excessive secretion of thyroid hormones. This alone cannot be used as a standard; some people say, "No. "Easy to be allergic means increased immunity." This point is actually quite controversial. When I went to the hospital to check for allergies, I heard the allergist doctor say that immunity is about balance, not stronger, the better. If the immune response is overactive, it will attack the normal tissues as foreign enemies, triggering autoimmune diseases such as lupus erythematosus and rheumatoid, and making severe allergies more likely. Only when allergies have been repeated frequently before and the frequency of attacks is significantly reduced now is a sign that immunity is improving. If you have never been allergic before and suddenly come into contact with all the allergens, it will be fine. Instead, you should be wary of whether the immune response is too weak.

To put it bluntly, our immune system is like a security team stationed in the body. A good state does not mean sounding the alarm every day and patrolling around to make you feel uncomfortable, nor does it mean fishing every day and not caring about foreign enemies coming in, but it is usually quiet and undisturbed. When viruses and bacteria do break in, it can be quickly dispatched to nip the risk before it starts, and prevent it from causing a large-scale "riot" that makes you uncomfortable for a long time.

Normally, if you find oral ulcers that were common in the past, they rarely occur now. Small scrapes and small cuts on your hands when cutting vegetables used to take three or four days to scab without pain, but now they dry up and heal in a day or two. When the season changes, you no longer get stuffy or runny noses. Tears, these small changes are actually much more reliable than the "rosy complexion" and "smooth bowel movements" promoted by health care product merchants. After all, poor bowel movements may be due to eating too carefully recently, and poor complexion may be due to staying up for two days. It really has nothing to do with immunity.
