Is it true that the higher the immunity, the better? These diseases pick people with good immunity

In the modern concept of health,"Boosts immunity"It has almost become the most important street street to fight diseases, from healthy foods to lifestyle advice, all emphasize the importance of strengthening immunity. However, the science behind this concept and the practical implications are far more complex than a simple slogan. The immune system, the complex network that guards health in the body, is key to maintaining health through its working mechanisms and homeostasis. When immunity changes from a shield to an attacker, the system that was meant to protect begins to inadvertently damage the body's own tissues, causing a series of health problems. Yes, over-strengthening of immunity is not always a good thing, and it can sometimes be a double-edged sword for the body.

The immune system is the body's guardian debut against external aggressors, including bacteria, viruses, and other factors that can be harmful to your health. However, the activities of this system are not always entirely conducive to health. When the immune response exceeds the body's needs, it may instead attack the host itself, causing a range of problems.

Given the complexity of the immune system, it's like a precise sword. When fighting diseases, this sword is able to provide the necessary protection. But when the balance is imbalanced, it can become an internal enemy. For example, autoimmune diseases occur when the immune system mistakenly recognizes healthy cells or tissues as a foreign threat and attacks. In this case, a highly active immune system is no longer a benefit, but a burden on health.

Autoimmune diseases are a broad category that includes a variety of diseases that all share a common characteristic: the immune system attacks and destroys normal body tissues. The occurrence of such diseases can be largely attributed to the overactivity of the immune system.

Rheumatoid arthritis, for example, is a common autoimmune disease in which the immune system attacks the joints, causing inflammation, pain, and even joint damage. This condition shows the other side of the immune system's powerful power – when it overreacts, it can cause lasting damage to the body.

An allergic reaction is an allergic reaction of the immune system to a substance in the environment that is supposed to be harmless. These reactions, ranging from mild discomfort to severe anaphylactic shock, are the result of the immune system's attempt to protect the body from an imaginary threat.

Allergic diseases, such as hay fever, asthma, and certain food allergies, highlight how overprotection of the immune system can backfire, causing the body to overreact to the everyday environment. This phenomenon illustrates that even in the normal functioning of the immune system, the intensity and range of its response need to be finely tuned.

The relationship between high immunity and chronic inflammation is of particular concern. Chronic inflammation is at the heart of many chronic diseases, including cardiovascular disease, diabetes (replaced here with "glucose metabolism"), and certain forms of cancer. This inflammation is often due to the constant activity of the immune system rather than a transient defense response.

In this context, the increase in immunity is not always positively correlated with the improvement of health status. Conversely, an excessive immune response can lead to or exacerbate chronic inflammation, which increases the risk of developing related diseases. Therefore, maintaining an appropriate level of activity of the immune system, avoiding its over- or under-activity, is essential for the prevention and management of chronic diseases.
