As the saying goes: 19 two nine not out of hand, three nine four nine ice walk, now to the nine cold days, the coldest season of the year, many people have a cold and fever, the body lazy, but there are also people who do not have any symptoms. We also often hear people praise: XXX resistance is really good. Today we will talk about how we can improve our body resistance when cold air comes. Resistance, as we often call it, is medically known as immunity. It is a person’s own defense mechanism, with the ability to identify and destroy “foreigners” (viruses, bacteria, etc.), simply put, the body’s ability to protect itself from a variety of pathogenic microorganisms. When the body’s immune function is low, the body’s defense cells show no resistance, then the virus, bacteria, etc. will take advantage of the situation, causing a variety of physical discomfort. Long-term low immunity is not only detrimental to health, but can also have a negative impact on work and life. Some people only show a decrease in white blood cell count and/or neutrophil count in their blood tests at the hospital. However, most people will only experience discomfort and physical examination will not reveal any abnormalities. If you often have the following symptoms in your daily life, it means that your immunity may have a problem. 1, easy to get sick: recurring cold within a year, some even become a routine; or every time you get sick, it takes a long time to recover; or others a cold you are susceptible to infection, these situations indicate that your immune system may have problems. 2, poor health: body tiredness, limb soreness, less gas, weakness, etc. If such symptoms often occur, and the examination does not have organic lesions, this may be your immune system problems. 3, gastrointestinal discomfort: frequent loss of appetite or diet slightly uncomfortable vomiting, diarrhea and other symptoms, which is also a manifestation of poor immunity. 4, easy to infect: small wounds in the body is also easy to cause septic infection or long time does not heal, which is also a manifestation of low immunity. 5, sleep disorders: long-term insomnia will cause forgetfulness, the body’s judgment and flexibility will be reduced, low immunity. 6, other: there are some people will show limb pain and other performance. If we have a lowered immunity, how can we improve it? Let’s take a look at the principles of healthy living. Reasonable diet: nutrition is the basis for improving immunity.

The human body needs a variety of nutrients, not picky and partial food, food should be coarse and fine, and less raw and cold food.

And a good social and friendly colleagues can reduce the chances of catching a cold or flu. Learn to relax, listen to more music, and talk to friends about life’s woes, which is of great benefit to improving the immunity of the human body. Improve the quality of sleep: by ensuring 7-8 hours of sleep a day, the chances of getting sick will be greatly reduced. Reduce the use of hormones: Many people will choose infusion when they have a cold, and in the case of fever, some will even apply hormones. Hormones can be applied, but they should not be used frequently, and too much use will lead to a decrease in immune function. Oral immunity-boosting drugs: There are many commonly used immunity-boosting drugs, such as western drugs: pitocin, transfer factor, etc.; Chinese herbs: ginseng, astragalus, ganoderma lucidum, etc..
