Decreased human immunity can easily lead to colds

The weather is unpredictable. Many people get colds accidentally. What is the pathogenesis of colds? How are different colds different?

Cold is a common disease with high incidence in our daily life. From a medical point of view, why do people catch a cold? What is the pathogenesis of a cold? Cold is a term in Chinese medicine, and Western medicine calls it a respiratory infection.

There are two main reasons why people catch a cold: 1 is an external cause, and 2 is an internal cause. The external cause is that the external evil invades the human body and causes people to get sick, and the internal cause refers to the decline of our normal resistance and immunity. The external cause is the determining factor, and the internal cause is the main influencing factor.

The external factors in Chinese medicine mainly refer to the six evils of "wind, cold, heat, dampness, heat". Western medicine believes that the external cause of a cold is acute inflammation caused by viruses or bacteria invading the human body, that is, viruses or bacteria multiply, replicate and release in the respiratory mucosa, causing the degeneration, necrosis, and shedding of epithelial cells, leading to inflammatory changes in the upper respiratory tract.

In addition, what are the symptoms of a cold? Which behaviors of people are likely to cause a cold? Liu Xin said that cold symptoms generally include headache, nasal congestion, runny nose, sneezing, aversion to cold, fever, floating pulse, and other main clinical manifestations. Intrinsic factors are an important factor leading to colds. When people's daily behaviors cause the body's resistance to decline, it is easy to cause a cold. For example, irregular life and rest, often staying up late, irregular eating, lack of exercise, cold imbalance, cold weather without clothes, frequent cold drinks in hot weather, excessive fatigue, and other behaviors, these behaviors cause the human body to appear weakened in immunity. With the intrusion of external factors, it is very easy to cause a cold.
