Reasons for decreased immunity

Immunity is something that each of us has, and it is used to resist certain diseases and maintain the health of the human body. However, the strength of each person's immunity is generally different. Some people have strong immunity, while others are relatively weak. And many times, the strength of our body's immunity is also affected by many factors. In other words, there are many factors that affect human immunity. So, what are the reasons for the decline in human immunity?

In fact, there are often many reasons that lead to a person's decreased immunity, but most people usually don't know much about this. Immunity is very important to our human body, so in daily life, most people pay more attention to maintaining immunity. So, let’s talk about some reasons for decreased immunity.

One is psychological anxiety or pessimism. Anxiety and pessimism can have adverse effects on the body's autonomic nervous system, thereby affecting the endocrine system and immune system, causing a sharp drop in human immunity over a period of time. The common mouth ulcers caused by "getting angry" are actually caused by anxiety affecting the body's immunity, giving bacteria that have been lurking in the human body for a long time an opportunity to get going. If you stay in an anxious and pessimistic mood for a long time, it may cause greater harm to your body.

The second is physical overwork. The mechanism by which excessive fatigue causes reduced immunity is the same as the former, which is to affect the autonomic nervous system and then affect the endocrine system and immune system. Improper weight loss, insufficient rest, long periods of heavy physical work, overeating, etc. will cause the body to be overloaded and lead to reduced immunity.

The third is insufficient exercise. Appropriate exercise can promote the body's internal circulation and endocrine system, improve the function of human organs, and thus enhance the body's immunity. Insufficient exercise will cause the body's various systems to be in a state of slackness. Once pathogens "invade", the various functions cannot be quickly mobilized and put into operation. The fact that people who do not exercise or exercise very little are more likely to get some common infectious diseases such as influenza than those who exercise regularly is proof of this. Fourth, the natural aging of the human body. As people age, they recover more slowly after being sick and are more susceptible to common infectious diseases such as colds. This is because the body's organs can no longer fully function after natural aging, or cannot reach the level of youth, resulting in a decline in the body's immunity.

Generally speaking, there are three common reasons for decreased immunity: psychological factors, excessive physical fatigue, and insufficient exercise. In fact, there are many reasons that cause a person's immunity to decline. So for all of us, if we often get sick or have a decline in physical strength in our future lives, we should consider whether it is caused by a decline in immunity, and then take correct countermeasures.
