In recent years, with the raging new crown epidemic, more and more people have begun to pay attention to the topic of immunity. So, how exactly does immunity work?
Today, let's unveil the mystery of immunity from the perspective of popular science and explore how to build an impregnable defense system!
Immunity refers to the body's ability to fight pathogenic microorganisms (such as bacteria, viruses, parasites, etc.) and their harmful substances. It is like a powerful army, guarding our health at all times. Immunity is mainly divided into two categories: non-specific immunity and specific immunity.
Non-specific immunization:Also known as natural immunity, it is the body's innate defense ability. It includes physiological barriers such as ** and mucous membranes, as well as phagocytic cells, natural killer cells, etc. The role of non-specific immunity is to block and eliminate pathogens, buying valuable time for specific immunity. 2.Specific immunization:Also known as acquired immunity, it is the body's ability to develop defenses through an immune response after exposure to a specific pathogen. Specific immunity includes both cellular immunity and humoral immunity, which can target specific pathogens with precision. 
Protects against pathogens:People with strong immunity are able to remove pathogens from their bodies more quickly and reduce the risk of infection.
Prevention of disease:People with strong immunity are not susceptible to certain genetic diseases and infectious diseases.
Anti-aging:Immunity is closely related to human aging. People with strong immunity age are relatively slow.
Improving quality of life:Strong immunity, which can improve the quality of life and reduce the number of diseases.
Eat a balanced diet:Maintain a balanced nutrition and eat more vegetables, fruits, nuts, meat, etc., to provide adequate nutrition for the body. (Nuts are recommended here, because I really like nuts, and I can indeed replenish the substances that the human body needs, so don't overdo it at that time.)Easy to get on fire! Regular work and rest:Maintaining a good routine and ensuring adequate sleep can help restore immunity. 3.Moderate exercise:Moderate exercise can strengthen physical fitness and improve immunity. It is recommended to do at least 3 times a week of moderate-intensity exercise. 4.Stay optimistic:A positive mindset helps boost immunity. Studies have found that optimistic people are more likely to overcome illness. 5.Reduce stress:Being in a high-pressure state for a long time can lead to a decrease in immunity. Learning to relax yourself, reduce stress, and help boost immunity. 6.Social interaction:Socializing well with others can help boost immunity. 
Although immunity is essential for human health, too strong immunity can also bring certain drawbacks.
For example, overactivation of the immune system can lead to allergic reactions, autoimmune diseases, etc.
Therefore, while boosting immunity, it is also necessary to pay attention to immune balance.
Immunity is an important guarantee of human health. Understand the role of immunity, master the methods to improve immunity, and let us protect our health and stay away from diseases!
