What is the root cause of people getting sick, and why do people get sick?

There are many reasons for people to get sick, and the environment, genetics, personal physique, personal living habits, etc., the patient itself will carry out metabolism, if living in an environment with poor air quality or the food eaten is contaminated, etc., there may be some toxins accumulated in the metabolic process, resulting in the patient getting sick.

In addition, malnutrition can also cause illness in patients. If there is overnutrition, it may increase the metabolic burden of patients, and they are prone to diabetes, hyperlipidemia, hypertension and other diseases, and malnutrition is also prone to anemia and other diseases. If the patient often stays up late or is in a psychologically stressful environment for a long time, it may lead to endocrine imbalance, which will lead to a decline in the function of the spleen and lungs.

Genetic factors are also one of the causes of illness, and if the parents have a genetic disease, the risk of the disease will increase significantly. With the increase of age, the patient's organs are aging, which is also easy to lead to illness, which is inevitable.

The causes of illness include infectious factors, genetic factors, environmental factors and lifestyle habits, which may be caused independently or superimposed, and more importantly, they can affect each other.

Human evolution has brought about pain such as low back pain, spinal curvature, etc.

The causes of non-communicable diseases, especially chronic non-communicable diseases, are more complex than infectious diseases and can be simply divided into genetic and non-genetic diseases.

People who lack exercise are susceptible to obesity and its associated diseases (such as diabetes, coronary heart disease, fatty liver, cholecystitis, cholelithiasis, spondylosis, colon cancer, etc.).

Alcoholics are susceptible to a variety of liver diseases, including cirrhosis and liver cancer.

People who stay up late and lack sleep are not only susceptible to various diseases, but also more prone to aging.

Understanding why people get sick is the key to understanding illness and life. So we can:

First, maintain good hygiene habits to prevent and reduce the occurrence of diseases;

Second, increasing exercise, maintaining a standard weight, adhering to a low-salt diet, and developing good eye habits can delay the onset of diabetes, essential hypertension and myopia, respectively;

Third, avoid overwork, avoid long-term strenuous exercise, avoid exposure to extremely harsh environments, and eat more high-fiber foods, which can delay aging;

Fourth, disease control, including timely detection of disease and correct and effective disease control.

Human beings exist in nature, and they are surrounded by all kinds of bacteria and viruses all the time. But humans rarely get sick. This is because the human body has a variety of defense systems to resist viruses and bacteria from the outside world to protect the stability of its internal environment.

WhileVarious immune cells involved in the protection of the human body include phagocytes, T lymphocytes, B lymphocytes, memory T cells, memory B cells, immune active factors, etc。When it comes to the body's immune system, we must know that the body's immune system is divided into two types: non-specific immunity and specific immunity. <>

These two immune defense systems constitute the body's three lines of defense. Only when the virus breaks these three lines of defense can it infect the human body and disrupt the homeostasis of the human body.

First of all, this first line of defense is composed of the human body's ** and mucous membranes and the substances secreted by them. The first line of defense is a type of non-specific immunity. All viruses and bacteria, they will destroy them as soon as they find them.

Secondly, the second line of defense of the human body is composed of some bactericidal substances (lysozyme, immunoactive factors, etc.) in body fluids and phagocytic cells. Like the first line of defense, the second line of defense is non-specific immunity. Phagocytes are not only present in the second line of defense, but also in the third line of defense.

And it has no specificity, as long as it is not the body's own cells or metabolites, phagocytes can engulf it. <>

The last thing to talk about is the third line of defense of the human body. The third line of defense is made up of the body's immune organs and immune cells. But not everyone has a third line of defense.

Some people are born unable to synthesize T lymphocytes, so they do not have a third line of defense. The third line of defense is the most important in the human body, which is divided into two types: humoral immunity and cellular immunity. It is mainly composed of phagocytes, T lymphocytes, B lymphocytes, memory cells, etc., which work together to maintain the balance of the human internal environment.

However, if people stay up late or are overworked, the function of the person's immune system will decline. This is the time when you are most likely to get sick. Therefore, for the sake of our own health, get up early and go to bed early, don't overwork, keep your mood comfortable, and the disease will naturally stay away from you.

The environment is an important source of disease.

It's actually the result of your body's cell genes interacting with your environment. If your body is in a good environment, your cell genes will adapt, so the genes will be expressed normally, and the result will be a healthy state; If your body is in a harsh environment, your cell genes will not be able to adapt, so the genes will be abnormally expressed, and the result will be a disease state. When a bad environment prevails, it is the road to disease; When a good environment prevails, it is the road to health.

It can be seen that a bad environment is an important source of disease.

There are two important factors:

1. Innate genes.

Innate genes are inherited from parents and grandparents. Your looks, your blood type, your personality, most of them are inherited from your ancestors. There's nothing we can do to change that.

2. The acquired living environment.

Two seeds fell from the same tree, one planted in fertile land and one planted in saline soil. You don't have to think about it to know what their fate will be, cells grow in our body fluids, as long as our body fluids are clean, that is, the environment is clean, then cells are naturally healthy.

Due to the poor lifestyle and poor diet, a large number of toxins enter our body, destroying the internal environment of the body's cells, so that the cell DNA can not replicate correctly, and the mild sub-health and serious diseases.

When you are in a bad mood**, endocrine and other diseases will appear. "The Yellow Emperor's Neijing" mentions "thinking about hurting the spleen", from the perspective of traditional Chinese medicine, every emotion can affect the internal organs, leading to problems in the operation of qi and blood in the human body.

Traditional Chinese medicine believes: "Thinking is qi knotting." "Excessive thinking can easily cause nervous system dysfunction, decreased secretion of digestive juices, loss of appetite, sluggishness, lack of food, haggardness, shortness of breath, fatigue, depression and discomfort.

Excessive thinking not only hurts the spleen, but also leads to poor sleep, and over time, the qi is not smooth, and all kinds of diseases follow.

Because there are a variety of bacteria in the natural environment.
