When we talk about “Immunity“, we are referring to the defensive capacity of the immune system, especially the resistance to infectious diseases. When we say a person’s immunity is high or low, we are generally referring to whether the person is susceptible to pathogens that can cause illness. For example, in the past two years, in the face of the new crown pneumonia, in the same situation, some people got sick and some were fine, some were mildly ill and some were dying.
Before the mass use of the hepatitis B vaccine, roughly 90% of the Chinese population was infected with the hepatitis B virus, but only a small percentage would develop viral hepatitis. In tuberculosis, for example, more than 500 million people in China have inhaled the bacillus through the respiratory tract, but there are only 1 million new cases each year.
The vast majority of people who have been exposed to Mycobacterium tuberculosis are able to stay healthy. All of this has to do with personal immunity. The immune system can be credited with defending us against various viruses, bacteria and other microorganisms.
It is because of the vital role of the immune system in fighting infectious diseases that people want to have a good immunity and thus a healthy body. So, what is immunity? How to strengthen immunity? We will explain these things about immunity.
The Immune system protects our body all the time
Our immune system is extremely complex, including immune organs (spleen, bone marrow, thymus, lymph nodes, tonsils, etc.), immune cells (lymphocytes, phagocytes, etc.) and immune molecules (lymphokines, immunoglobulins, lysozyme, etc.), etc.
The immune system has a large organization, many members, and is extremely sophisticated as it regulates each other and is intertwined. The immune system is spread throughout the body and involves many types of cells, organs, proteins and tissues. It protects our body against foreign invaders and keeps it in a healthy state. Without the immune system, our body would be exposed to foreign attacks such as bacteria, viruses, and parasites.
Immunity decreases with age
How can we assess whether a person has a high or low immunity? Currently, we do not have a viable way to measure or assess the level of immunity, Yang Huaixing said. However, one thing is certain: as we age, our immune capacity decreases.
Studies have found that older people are more likely to develop infectious diseases than younger people. According to a study published March 17 in the medical journal The Lancet, the chances of repeat infection from New Coronary Pneumonia are low, but repeat infection is relatively common in people 65 and older.
Most patients with new coronary pneumonia appear to be able to avoid reinfection for 6 months after cure, and the few repeat diagnoses are predominant in people 65 years of age and older, the study said. The immune system of older people is only about 47 percent effective in protecting against repeat infections, compared with about 80 percent in younger people, according to the study. According to the researchers, this result proves that everyone needs to be vaccinated, especially those who are older and more likely to develop severe disease.
Protect your Immune System to prevent lowered immune function
So how do you prevent a lowered immune system, or how do you restore a lowered immune system? It is important to master the following six points to boost your body’s immunity
Balanced diet. Try to have a balanced diet to ensure that our immune system has enough energy and nutrients to fight pathogens. Do not be partial to eating, eat more vegetables and fruits, meat and vegetables.
Try not to smoke or drink. Try not to smoke because smoking lowers the immune system. And too much alcohol will lead to a decrease in resistance, drinking directly hurt the liver, liver injury, vision is bound to decline, the body’s detoxification ability also decreased, resulting in a decline in immunity, easy to infect other diseases and tumors.
Rest well. The immune system will change with the biological clock, so the disruption of the biological clock will also affect the immune system. For example, when staying up late often, the corners of the mouth will be prone to blistering, which is when our immunity is lowered and the herpes virus comes out to move and cause herpes to occur.
Exercise regularly. Although the mechanism is not clear, moderate exercise can boost our immune system and thus help us fight pathogens.
Adjust your mindset. In particular, do not allow yourself to live in a stressful situation. Mindset and stress can affect immunity, although the exact mechanism involved is also unclear, probably because of the interaction between the nervous system and the immune system.
Do not abuse drugs. On the one hand, drugs (such as antibiotics) reduce the opportunity for the immune system to fight pathogens, which it needs to grow. On the other hand, some drugs can also act directly on the immune system and reduce the body’s immunity.
These foods can effectively boost Immunity
In addition to protecting your immune system, regular consumption of the following foods can also improve your immunity
Royal jelly: Royal jelly has the ability to improve nutrition, replenish brain power, improve body immunity, prevent cardiovascular and cerebrovascular, etc. It also has the ability to heal anti-inflammatory, relieve pain and promote wound healing. In addition, fresh royal jelly is a nutritious food with high active ingredients that can be consumed directly by humans, and has a good health effect on the body when taken for a long time.
Rapeseed pollen: The pollen mass of rapeseed flowers is yellow in color. The pollen polysaccharide extracted from the pollen can significantly improve the non-specific cellular immunity and specific humoral immunity of the body. Taking pollen polysaccharide can enhance the body’s immunity, which has a very important role in maintaining the body’s health and preventing diseases.
Chinese wolfberry: Chinese wolfberry is a traditional precious Chinese herbal medicine, known as “red treasure”, rich in plant polysaccharides, protein, vitamins and other nutrients. Among them, Chinese wolfberry polysaccharide is a water-soluble polysaccharide extracted from Chinese wolfberry. Research shows that the wolfberry polysaccharide is the main active ingredient of wolfberry to regulate immunity and delay aging, can improve the elderly easily fatigue, loss of appetite and blurred vision and other symptoms, and has a lowering of blood lipids, anti-fatty liver, anti-aging and other effects.
Lotus seeds: lotus whole body is a treasure. Lotus, lotus seeds, lotus seeds, lotus roots and lotus leaves all have their unique effects. Lotus seeds contain the component lotus polysaccharide to enhance human immunity. Lotus seed polysaccharide has the ability to enhance the immunogenic suppressive effect of cyclophosphamide, enhance human immunity and promote the transformation of lymphocytes.
Job’s tear: It is a dual-use crop for medicine and food. The medicinal use of Job’s tear was first recorded in “Shen Nong Ben Cao Jing”, which believes that Job’s tear is good at treating rheumatism and paralysis, and can lower gas and remove dampness, and can also lighten the body and benefit the qi when taken for a long time. It can delay aging and improve the body’s immune system. Lowering blood sugar: Job’s tear polysaccharide content is rich, including modern pharmacological research shows that Job’s tear polysaccharide A, B, C has the effect of lowering blood sugar. Enhance physical fitness: enhance immunity and anti-inflammatory effect, barley oil has a promotional effect on cellular immunity and humoral immunity.
At the same time, experts also remind us that the adjustment of health status is a gradual process of exploration, we should often focus on their own situation, according to different situations “symptomatic” adjustment, in addition to the appropriate amount of food to enhance immunity, but also to ensure a balanced intake of protein, minerals, vitamins, water.
