Expert: Under the epidemic, it is very important to protect your immunity! Do 3 points, the immunity is naturally strong

Someone once asked, "In the face of COVID-19 pneumonia, is there any special medicine?"

In this regard, Professor Zhang Wenhong, director of the Department of Infectious Diseases of Huashan Hospital Affiliated to Fudan University, gave the answer: " The most effective drug is human immunity. "

Recently, academicians and experts of the Chinese Academy of Engineering also mentioned immunity at an event, "The occurrence, development and prognosis of new coronavirus pneumonia are closely related to the quality of the body's immune system. The body must truly remove the COVID-19 virus . Clean, relying on your own immune system. ”

Experts and academicians call on everyone to strengthen their immune system, maintain a peaceful mind, and do moderate exercise to improve their immunity. How important is immunity to the human body?

1. Immunity is the best "doctor"

In daily life, many people know that immunity is very important to human health, and they all say that it is necessary to improve immunity. What exactly does immunity mean?

Immunity is a kind of "instinct" of the human body. Relying on this ability, the human body can identify "self" and "non-self" components, thereby destroying and rejecting viruses and bacteria that enter the human body. It can be said that immunity itself is the body's own "security guard" .

In an interview with CCTV, Wang Guiqiang, director of the Department of Infectious Diseases at Peking University First Hospital, used COVID-19 as an example of the interaction between pathogens and immunity.

Professor Wang Guiqiang believes that COVID-19 itself is a typical pathogenic microorganism. When it fights with human immunity, it will lead to various clinical types : asymptomatic infection, mild, common, severe and critical.

It should be reminded that even if the immune system is strong, the attack power of the new coronavirus pneumonia cannot be ignored. Therefore, to fight against the COVID-19 virus, you must wear a good mask every day; regularly disinfect your home environment, daily clothes, etc. with high temperature or alcohol, and avoid blind or inappropriate use of antibacterial drugs.

Second, these behaviors will accelerate the "loss" of immunity, try to avoid

With the development of the epidemic, more and more people pay attention to the improvement of immunity. But some behaviors in daily life, but will reduce the immune system.

1. Don’t eat breakfast

A study by the Centre for Occupational Diseases and Psychology at Cardiff University in the United Kingdom shows that people who skip breakfast are more likely to cause metabolic disorders in the body, resulting in changes in the body's internal environment and more susceptible to colds and other diseases.

2. Too much salt

Eating too salty is not only not conducive to blood pressure control, but also disturbs the immune function of the human body environment and weakens the bactericidal ability of neutrophils in white blood cells.

3. Smoking and drinking

Both active and passive smoking are harmful to health and reduce the ability of the immune system. At the same time, excessive drinking can weaken the immune system, making people more susceptible to foreign pathogens.

4. Less exercise

Through exercise, you can burn fat and raise body temperature, which not only stimulates blood circulation, improves cardiopulmonary function, but also helps immune cells to phagocytose bacteria to a certain extent.

Insufficient physical activity will reduce cardiopulmonary function and blood circulation speed, and also affect immunity.

5. Lack of sleep

Studies have found that sleep can directly or indirectly participate in the regulation of the immune system. When sleep is disrupted, it can affect the body's endocrine disorders, thereby changing the balance of the immune system.

Especially when these symptoms appear in the body, the immunity may have been weakened, and the body is reminding that it is time to improve the immunity:

• Fatigue often: relieved slightly after rest, but reappears after a few days;
• Easy to be infected by diseases: there are cold patients around, and they will be infected soon;
• Wounds are susceptible to infection: Wounds are difficult to heal and sometimes become red, swollen and pus.

How can we improve our immunity in our daily life?

3. Improving immunity is not "one-shot"

Gao Jian, director of the Nutrition Department of Zhongshan Hospital Affiliated to Fudan University, believes that in order to scientifically improve immunity, it needs to be supplemented from three aspects:

1. Balanced and healthy eating habits

Protein is an important nutritional element for immunity. The elderly should consume about 60g of protein every day . Eggs, milk, lean meat, etc. are all good high-quality proteins.

The diet is not blindly pursuing lightness, which can easily lead to the lack of certain nutrients. According to the recommendations of the dietary guidelines, food diversity should be guaranteed , three meals a day, calories, vitamins, minerals, dietary fiber, protein, etc. should be ingested.

2. A regular lifestyle

On the basis of a balanced diet, exercise is very effective for improving immunity. Regular adherence to exercise will gradually increase the basic immunity level and keep the immunity at a continuous peak stage.

The best exercise is 30 minutes to 45 minutes of moderate-intensity exercise each time, about 5 times a week, and persist for more than four weeks for a long time. Recommend 3 moderate-intensity aerobic exercise for everyone: jogging, cycling, and equipment exercise .

In addition to regular exercise, you should also maintain a good regular schedule.

Wang Yuedan, a professor at the Department of Immunology, Peking University School of Basic Medicine, said that the human immune system will be affected by the rhythmic secretion of adrenal cortex hormones. Therefore, a good and regular work and rest is an important guarantee for maintaining the function of the immune system .

3. Scientific nutritional supplements

With the accelerated pace of life, many people choose fast food and convenient food. But most of these foods are not nutritious. In order to boost immunity, additional nutrients should also be properly supplemented:

• Protein: Protein is not only the basis of life, but also the basis of immunity.
• Probiotics: Probiotics can maintain intestinal microecological balance and prevent secondary bacterial infections.
• Polysaccharides: can enhance the combat effectiveness of neutrophils.
• Trace elements: lycopene, lutein, EGCG, various vitamins, etc., can protect immune cells from free radical oxidative damage.

Improving immunity means keeping the immune system in a balanced state, rather than making it too strong. If the immunity is too strong, it may also attack non-pathogenic substances, which can easily lead to allergic reactions. Of course, if the immune system is too weak, it will easily lead to poor disease resistance in the body.

It can be seen that the immune system itself is a "double-edged sword", blindly pursuing excessive immunity, but instead makes the body fall into some kind of injury, which is not worth the loss.
