 Prevention novel coronavirus pneumonia, how to enhance immunity of the public


Novel coronavirus, Chinas latest 2019 new coronavirus epidemic situation and risk assessment report, released in January 27th, Chinas centers for Disease Control and Prevention said, the proportion of male to female is 1.16:1. The median age was 49 years old, ranging from 9 months to 96 years old. Less than 0.6% of the cases were under 15 years old. The average incubation period was 10 days (1-14 days). Patients with basic diseases and old age are prone to severe disease and death. This data suggests that different genders and different age groups have different risk of disease. If you are a healthy young person with good immunity, the risk of infection will be reduced, and the chance of recovery after infection will be greater. Therefore, strengthening immunity will also play a very good protective role when you are far away from the source of infection.

Human immune system

How to resist the infection of bacteria or viruses?

The mucosal system of human body is the first wall of immunity. Before bacteria or viruses in air or food invade human body, it is necessary to break through the mucosal defense line (including respiratory tract, gastrointestinal tract, urogenital tract and other mucosal barriers). Protecting the mucosal immune system can improve the bodys immunity.

The patients with low immune function are easy to be infected by virus and bacteria, and they are more likely to get disease than those with normal immune function or get worse in the same environment. When the immune function is not perfect, the immune cells will kill the healthy cells of the patients by mistake, and they will not stop killing. In the acute viral infection, the immune response is intense, the immune cells kill the red face, all the way to kill even healthy cells, and even lead to complications, and finally fatal.

One of the phenomena called cytokine storm is that the immune balance is broken, resulting in the accumulation of too many immune cells and inflammatory factors, causing tissue congestion, edema, fever, injury, until systemic inflammatory response, leading to multiple organ failure and death.

In 2019, patients with severe coronavirus infection showed a significant increase in proinflammatory cytokines such as IL-6, TNF - u03b1, IFN - u03b3, which was characterized by a cytokine storm. At present, the cause and mechanism of cytokine storm are still unclear.

Novel coronavirus pneumonia

How to improve self immunity?

The improvement of immunity does not need to rely on any expensive ingredients. It is the kings way to start from daily life.

Nutrition balance: keep 10 dietary classics in mind

The normal function of the human immune system needs to be supported by enough nutrients. In daily life, we need to take enough and appropriate proportion of nutrients to maintain the normal operation of the immune system. First of all, we should ensure the balance of protein, fat and sugar, in which protein is an important component of the body. Without protein, the body can not produce enough immune cells and molecules, thus affecting the bodys immunity. Novel coronavirus pneumonia is a popular science in the past. We have introduced the diet and nutrition science popularization of six cases of public health emergency response series to prevent and control the epidemic of new coronavirus pneumonia. Refer to the healthy diet in the dietary guide for Chinese residents, and keep in mind 10 dietary classics: various foods, mainly grains, coarse and fine combination; eat more fruits and vegetables and potatoes; eat milk, soybean or its products every day; often eat appropriate amount of fish, poultry, eggs and lean meat; reduce the amount of cooking oil, eat light and salt less meals; do not overeat, exercise every day, and maintain healthy weight; three meals Match reasonably, snacks should be appropriate; drink plenty of water every day, and choose drinks reasonably; such as drinking should be limited; eat fresh and healthy food.

Rational aerobic exercise: scientific and appropriate aerobic exercise step by step

Exercise is closely related to the immune function of the body. Regular and appropriate exercise can enhance the immune ability of the body and enhance the resistance to infectious diseases.

The novel coronavirus can be stimulated by scientific aerobic exercise at home, such as jogging in place, half height lifting, half jumping, skipping and shuttlecock. It is worth noting that exercise can only speed up the heart rate. If it is too intense or over an hour, the body will produce some hormones and inhibit the activity of the immune system. Short time limit exercise leads to acute inflammatory reaction, long time and heavy load exercise can inhibit the function of immune cells. Long term engaged in high-intensity sports training (especially physical endurance projects), the production of lactic acid in the body will increase, and research shows that the accumulation of lactic acid will inhibit the immune response of the body, increase the susceptibility to various diseases, reduce the resistance, and form sports immunosuppression phenomenon, so it is recommended not to exercise too much.

Sleep: 7-8 hours of sufficient high quality sleep to avoid staying up late

Sufficient and quality sleep is conducive to improving the bodys immunity. During sleep, the immune system of the human body can be restored and improved to some extent. The cells with immune function and the immune active substances produced in the body are increased, and the ability to produce antibodies is also increased. On the contrary, sleep deprivation can weaken the immune system of human body in various aspects, lead to the decrease of human immunity, reduce the number or activity of immune cells, and block the production of cytokines and inflammatory mediators. In addition, staying up late has become a common practice for modern young people, but actually sleep is the key to improving immunity. Research shows that the content of T-lymphocytes and B-lymphocytes in the body with good sleep quality is significantly higher than that in the people with poor sleep quality, while T-lymphocytes and B-lymphocytes are the main force of the immune system, and their level can directly affect the human bodys ability to resist viruses and bacteria u3002

Therefore, adequate sleep is helpful to improve the bodys immunity. Therefore, it is very important to keep healthy sleep for 7 to 8 hours every day, reduce or avoid staying up late, in order to prevent virus invasion and defeat epidemic situation.

Mood: keep pleasant mood and reduce anxiety

Emotion and immunity are related by neuroendocrine immune regulatory network. The neuroendocrine immune system of human body is a whole. Many neurotransmitters secreted by the nervous system will directly affect the immune system and endocrine system. At present, the new coronavirus epidemic situation, peoples self danger inevitably produces negative emotions, but when the negative emotions are too large, they often create huge pressure on people, and it is this pressure that will strike our immune system, affect the number of white blood cells and antibodies in the blood, as well as the function of immune cells, and even excessive anxiety makes the body produce fewer antibodies against harmful substances; moreover, The duration and nature of negative emotions are related to the degree of immune change. For example, the longer the negative mood lasts, the more pessimistic it is, and the more lymphocytes of special types are reduced. In the end, people who are originally healthy often have various symptoms of discomfort, which is not worth the loss. On the contrary, positive and optimistic emotions can enhance peoples immunity, reduce the bodys inflammatory response, and increase the bodys resistance to virus infection during the epidemic.

Therefore, during the epidemic period, we should adjust our mind, keep a happy mood, and live an optimistic and positive life.

The house is not isolated from the sun

Ultraviolet radiation on the skin can help vitamin D to transform and generate in the skin, and vitamin D not only plays an important role in the immune regulation of the bodys blood level, but also regulates the functions of T, B lymphocytes and monocyte / macrophage, reducing the incidence of some chronic diseases such as infectious diseases, tumors, autoimmune diseases, heart diseases, etc. The vast majority of people in the sun 10-20 minutes a day can be longer, but generally recommended in 30 minutes. Pay attention to the indoor sun exposure during the epidemic, and make sure to open the window to let the sun directly contact with the skin. Because it can promote the metabolism of minerals and the formation of vitamin D ultraviolet, the penetration ability is weak, so it can not achieve the goal through the glass sun. Show your face and hands in winter is the best choice. After basking in the sun, we must drink more water and eat more fruits and vegetables to supplement vitamin C, which can inhibit the production of melanin and prevent sunburn. If it can not meet the conditions of sun exposure, some vitamin D preparations can be reasonably supplemented. Work together to overcome the epidemic, and a better tomorrow is ahead! Please I believe that the epidemic will pass, continue to pay attention to health, health is the eternal topic of life! Source: surging news editor: Wu Yanli, nbjs6202
