Questions about immunity.

Teach you 1 tricks to improve immunity

Immunity can prevent bacteria and viruses from entering the human body and help patients recover. It is closely related to endocrine and nerves, and people's lifestyle and emotions directly affect the immune function. Dr. Lee Burke of the University of California School of Medicine wrote on the website Embodiment: "Years of research have shown that you can live a healthy and happy life as long as you pay attention to some simple details of your life." The following are 1 ways to scientifically improve immunity:

1. Spend more time with friends

When you are with friends, people's immunity will be in a good state because they feel friendship and social recognition. In order to confirm this view, the researchers of the Paris Center for Physical and Mental Health exposed the participants to the cold virus, and then the researchers tracked and monitored their social interaction. It turns out that people who spend more time with friends, family and colleagues are less likely to catch a cold. At the same time, physical contact such as hugging and touching can also make the immune cells of the human body more active.

Second, listen to your favorite music

Listening to music can also activate your immunity, but only if you really like it. "The same piece of music sounds like Yue Xian to some people, and it may be noise to some people." Dr. Burke said, "The key is to choose music that can soothe your heart." Good music, like food, can stimulate the pleasant part of the brain, thus improving immunity.

Third, reduce noise

Noise not only harms people's hearing, but also causes muscle tension, rapid heartbeat, vasoconstriction and digestive discomfort-this is the same as the body's reaction when it is scared or stressed. If people are exposed to noise for a long time, it will lead to adverse changes in blood pressure, cholesterol level and immune function. Cornell University in the United States found that women who work in noisy environments release more adrenaline than women who work in quiet offices, and are more likely to suffer from heart disease. The car flute, dog barking and other sounds that make people feel uncontrollable are more harmful to the human body. Therefore, people should try to control the sound around them, even if they wear headphones, or ask restaurant owners and gym managers to turn down the volume of the stereo.

Fourth, keep a positive attitude

Immunity will be hinted by thoughts and feelings, so we should keep a positive attitude. Researchers at the Mayo Clinic in the United States found that optimists live 12 years longer than pessimists when they are young. Recently, Anna L. Masland, a psychologist at the University of Pittsburgh Medical Center, also found in her research that people who are negative, depressed and feel pressure easily are much weaker against hepatitis virus than their optimistic peers.

5. Reasonable diet

Lack of any kind of nutrition will lead to recurrent and long-term diseases. When people feel hungry, the body will secrete adrenaline; If you lose more than 85g per week, T cells that resist diseases and foreign viruses will be inhibited. In this regard, experts suggest eating some foods containing unsaturated fatty acids, taking enough protein, eating more fruits and vegetables, and drinking more fruit juice and boiled water. However, the effect of health care products that claim to improve immunity is not obvious.

6. Laugh loudly

Anger and sadness can damage health, while laughter has the opposite effect. Laughter can make immune cells more active. To confirm this statement, Burke showed students a funny video and measured their immune response. It turns out that even hearing a humorous joke can improve immunity. In addition, laughter can promote circulation and digestion, lower blood pressure and relieve muscle tension.

VII. Use your brain more

Active thinking activities can improve your immunity. Marianne Diamond, a neuroscientist at the University of California, found in her research that playing bridge can stimulate the activity of immune cells. Her research revealed for the first time that the part of the brain responsible for planning, memory, judgment and abstract thinking is closely related to immunity. Diamond said: "Any thinking activity, as long as it is applied to the intellectual function of the brain, will be good for immunity."

Eight, more activities

Regular and long-term moderate exercise can enhance the body's resistance. Burke said: "Physical exercise is not only good for cardiovascular system, but also good for improving mood and reducing stress." However, the intensity of activities should be appropriate. If you feel tired and exceed your usual tolerance, you should adjust it in time.

Nine, learn to relax

Stress will make the human body secrete steroid hormones and adrenaline, which will slow down the immune response. This well explains why people are especially prone to catch a cold when they are under pressure, such as facing the final exam and emotional crisis. In addition, anxiety caused by stress will also reduce human resistance. Regular practice of relaxation techniques, such as aerobic exercise and gradual relaxation of whole body muscles, can inhibit the release of stress hormones and enhance immune function.

1. Turn off the light

Melatonin, a disease-fighting hormone, is produced in the dark. Lack of sleep or being in the light for a long time at night will reduce the release of melatonin and increase the secretion of estrogen, so it is easy to get breast cancer. Several recent studies have shown that the proportion of women who work at night is as high as 6%, and the proportion of women who like to make light in the bedroom bright is even higher. The proportion of blind women suffering from breast cancer is 2%-5% lower than that of normal people. Even weak light sources such as bedside alarm clock and nightlight can inhibit the release of melatonin. Therefore, the darker the bedroom, the better.

how to improve immunity?

The sufficiency and balance of nutrients in human body are related to the immune strength of the body, and are also related to some infectious diseases. According to the existing nutritional research results, the human body will be fully supplemented with nutrients, which will greatly improve the human body's immunity to diseases and play a role in preventing atypical pneumonia. So what is immunity? Immunity is simply the human body's resistance to various diseases, and the resistance comes from the immunity in the body, which consists of immune organs such as thymus, bone marrow, spleen and lymphoid tissue and immune cells such as macrophages, natural killer cells and lymphocytes.

A sound immunity has three functions, one is defense. Strong immunity can help the body to eliminate foreign bacteria and viruses and avoid diseases, and has the defense ability to protect the body from damage; The second is the stable function. Good immune function, can help the body repair or eliminate metabolic, damaged or aging dead tissue cells in the human body, and maintain the internal environment of the body's metabolism in a stable state all the time; The third is the monitoring function. Strong immunity can help the body kill and eliminate abnormal mutant cells.

Only when the various functions of the human body reach a balanced state can health be guaranteed, and the nutritional status of the body is closely related to the strength of immune function. In the process of supplementing nutrition, we should pay attention to ensuring the immune ability of the body through balanced nutrition.

Three Steps of Balanced Nutrition and Immunity How do several typical immune-related nutrients build human nutrition-immunity?

First of all, the combination of "VA+Zn" (vitamin A plus zinc) constitutes the first step of the trilogy of balanced nutrition and immunity, which can help prevent the virus from entering the human body and protect the respiratory tract from infection. Medical experiments show that vitamin A is an essential substance to maintain the normal function of epithelial tissue, which can promote the differentiation and repair of epidermal cells such as respiratory tract, ensure the integrity of epidermis, and thus resist the invasion of germs. Vitamin A is called "anti-infective vitamin". The synergistic effect of zinc and vitamin A can improve the absorption and operation of vitamin A. Therefore, the simultaneous action of vitamin A and zinc can effectively prevent the virus from invading.

vitamin c constructs the second step of "balanced nutrition and immunity trilogy", which helps to kill viruses entering the human body. Because it can interfere with the virus invading white blood cells, activate white blood cells all over the body, enhance the phagocytosis of white blood cells to the virus, and kill germs, thus enhancing the immunity of the human body and protecting the human body from the virus. The content of vitamin C in white blood cells of patients with cold decreased obviously.

in addition to trace elements, there is taurine. Taurine is an amino acid, which can promote the growth and reproduction of immune lymphocytes. In addition, it can clear away heat, relieve pain, and relieve fever, a symptom caused by the body's self-regulation defense against viruses, which is the third step of the trilogy of balanced nutrition and immunity. When the human body is seriously damaged, taurine also plays the role of clearing away heat and reducing fever, thus enhancing the resistance of the human body.

that is to say, if people, especially children, can supplement a variety of nutrients that are beneficial to improving human immunity in a balanced way and build an immune protective barrier, they can effectively protect the body from viruses.

netizens recommend economical and practical methods:

1. Exercise. Of course, it is reasonable exercise, and you may exercise when you are tired. It is best to do safe exercises every day, such as walking and jogging. Personally, I recommend walking more stops on the way to or from work, which saves money and is safe. It will be effective if you persist for 3 months.

2. Pay attention to diet. If you are not healthy and picky about food or don't pay much attention to your diet, you haven't improved your immunity. If possible, drink milk every day. I feel much better after drinking milk for a year, and I don't have frequent colds.

In fact, what you eat is really important. If you insist on treating every meal well and pay attention to the reasonable collocation of vegetables, meat, fish, eggs and grains, your immunity will be improved.

3. If you often have a sore throat, it may be an upper respiratory infection. Insist on using salt water to stir the mouth.

what I said is cheap, effective and safe, but the most important thing is to stick to the method. Come on!
