Today, we will talk about the influence of this "army" on us.

Today, how to improve the immunity of this "army" to us has attracted much attention. What exactly is immunity? Part of human immunity? How to judge low immunity? How to improve immunity?

First, what is immunity?

After hundreds of thousands of years of evolution, human beings have the ability to resist foreign viruses and bacteria, and this ability is immunity. The immune system is like an "army" in the human body. Every day, there is a "war" in the body, but most of the time you don't know it, because the "human army" is in absolute advantage. When your body temperature rises, your whole body aches, you have a lot of runny nose and tears, and the pain is unbearable, it means that the "army" in your body begins to "fight" to open your body's "self-protection". This "army" hidden in the human body is the "immune system", including immune organs such as bone marrow, thymus, spleen, lymph nodes and tonsils. For example, when the body temperature rises with fever, the reactivity of the immune system increases, the number of immune cells increases, and the bactericidal activity increases.

Second, the composition of human immunity.

(1) Natural immunity is the basis of human immune function, which is related to heredity, age and other factors, and changes with age.

(2) Specific immunity refers to the immunity produced after contact with a specific antigen (such as vaccine).

(3) Variable immunity mainly refers to the immune ability that can be improved through acquired regulation. Because the human body's resistance to diseases is the sum of these three kinds of immunity, and the probability that the innate basic conditions can be changed is very small, then the acquired "variable immunity" becomes the "top priority".

Third, the performance of low immunity

The main consequence of decreased immunity is that the human body is more vulnerable to viruses, bacteria and so on. In most cases, it will be expressed and judged by the symptoms that people feel physically. Easy to catch a cold, persistent high fever, loss of appetite, anxiety and irritability, listlessness, insomnia and forgetfulness, repeated constipation, dry eyes and so on. The above symptoms indicate that immunity is reduced. We should find out the subtle changes in our bodies in time, and it is not because we are infected with the virus that our immunity is low.

Fourth, how to improve immunity

The statement that "I am the first person responsible for health" fully proves the importance of "systematic health management". From the multi-dimensional causal analysis of health, "nutrition, energy consumption, training and reconstruction" are indispensable. In addition to reasonable daily dietary intake and scientific exercise, "the continuous enhancement of immunity" must be supported by "advanced scientific and technological achievements and tools". I suggest that you supplement vitamins C, zinc, multivitamins, probiotics, protein powder and other nutrients in time to help you "enhance your immunity" and get twice the result with half the effort.
