The most powerful antiviral "drug" you and I already have

The outbreak of the novel coronavirus (2019-nCoV) has attracted wide attention Although the virus has a high infection rate, most of the patients have good prognosis The cure rate has risen rapidly in the past week Thanks to the dedication of every angel in white fighting in the front line and every anti epidemic fighter in different posts In addition, we can not ignore the important role of our immune system in the process of virus resistance in the absence of specific drugs Novel coronavirus pneumonia professor Huang Bo, vice director of the China immunology Association recently mentioned: "the body eventually removes the virus, not by drugs, but by your immune system." 1, novel coronavirus pneumonia is not effective, and ultimately it depends on our own immune system to achieve self-healing Therefore, novel coronavirus is also helpful for the public to enhance their immunity, Huang also said in an interview We often say that immunity refers to the function of our immune system The immune system is like a bodyguard It can not only resist the invasion of foreign viruses, bacteria and other pathogens (immune defense function), but also remove the aging, mutation, deterioration or death cells (immune monitoring and self stabilization function) in the body to protect the health of the body The state change of the immune system is closely related to the occurrence and development of diseases The insufficient external defense function of the immune system may lead to bacterial or viral infection, and if the external defense function is too strong, inflammation and other phenomena may occur; when the internal immune monitoring and self stabilization function of the immune system is insufficient, diseases such as cancer may quietly grow, while when the immune monitoring and self stabilization function is too strong, It may also lead to autoimmune diseases Taking this epidemic as an example, in the first batch of newly diagnosed severe patients, some patients have "cytokine storm" According to the previous SARS and Middle East respiratory syndrome cases, cytokine storm is the real killer, which can trigger the immune system to attack the body violently When a large number of 2019 ncov attacks the human body, it will lead to immune system disorder, make its firepower fully open, and generate cytokine storm The "suicidal" attack on the immune system will not only damage the virus, but also cause a large number of self cells to be attacked, which is an important cause of acute respiratory distress syndrome and multiple organ failure Therefore, good immunity does not simply mean a higher immune killing and attacking ability, but that our immune system can properly fulfill its mission, and at the same time ensure to play its protective role, it will not let the human body cause disease due to the excessive activation of immunity It depends on a large and complex immune network composed of hundreds of different immune cells All the typical immune responses are produced by a variety of different immune cells, just like a huge and precise instrument Each immune cell performs its own duties in it, one part plays the role of phagocytosis and killing, such as macrophages, natural killer cells (NK cells) and cytotoxic T cells, the other part plays the role of auxiliary and signal transmission, such as auxiliary T cells Cells and dendritic cells (DC); some of them will play an immunosuppressive role, such as Treg cells, and finally achieve a dynamic balance of immunity Once this balance is broken, it may lead to disease In the immune system, all kinds of immune cells cooperate to maintain a dynamic balance Therefore, it is very important to pay attention to the state of our autoimmune system every day Just as we always pay attention to sensitive health sensors, once we find the immune imbalance, we can timely carry out health intervention, which may reverse or slow down the emergence of disease Of course, because the immune system is in dynamic balance, when some immune cells are out of balance, the compensatory function of other immune cells will appear, which explains why, when we conduct a more detailed blood immune cell function test, even if there is a certain immune cell content beyond the normal range, the overall health condition is good 3 Therefore, the detection of the content of some immune cells alone is not enough to effectively reflect the health status of the body A practical and effective evaluation of the immune system is not only to evaluate the proportion of a variety of immune cells, but also to evaluate whether the synergistic mode of various immune cells is in a normal dynamic equilibrium state In fact, the most simple and effective way is to adhere to good living habits, work and rest rules, diet balance and moderate exercise Work and rest regularly, while ensuring adequate sleep A number of studies have shown that sleep problems are related to a series of diseases such as obesity, cardiovascular disease, metabolic disease and even Alzheimer's disease Lack of sleep and the disorder of biological clock will also directly affect the immune system's response ability and defense ability Balance diet, quit smoking and drink less Cells need to use nutrients for metabolism, and the work of the immune system must be guaranteed by nutrition But eating well is not equal to good nutrition Nutrition should be systematic Food should be complete in variety, sufficient in quantity, appropriate in proportion and balanced in supply and demand Exercise in a planned and moderate way In 2019, nature reviews published a detailed explanation of the relationship between exercise, immunity and disease 4 they found that during exercise, skeletal muscle can secrete cytokines, such as IL-6 IL-6 has an anti-inflammatory effect and stimulates the adrenal gland to secrete a second anti-inflammatory signal, cortisol In addition to IL-6, skeletal muscle will also secrete IL-7, IL-5 and other cytokines, stimulating T cell activation and NK cell production In addition, regular exercise will also reduce virus infection and increase the diversity of intestinal microflora So what is real sport? It should be a planned, repetitive exercise aimed at improving or maintaining physical health At the moment of the epidemic, all we can do is to guard carefully, and at the same time, relax and don't panic It's good to eat, sleep and exercise at home Take up our own most powerful weapon, the immune system, to protect our health and wait for the epidemic to fade away and spring to bloom Once again, I salute the angel in white and everyone who participated in the anti epidemic! reference: 1 http://
