What are some tips for preventing diseases?

There are many causes of disease. To prevent diseases, we must find out the relationship between diseases and pathogenic factors, and eliminate or avoid these pathogenic factors to keep the human body in a relatively safe state. However, nature is a relatively open environment. If a person wants to survive and develop, it is impossible to be completely isolated from the world. In the long process of evolution, the human body has formed a certain self-defense system, that is, the immune system. At the same time, humans also have the instinct to seek advantages and avoid disadvantages, and have the ability to appropriately self-compensate and restore balance, the most typical of which is regeneration. Preventing disease should start with understanding the disease. Diseases are divided into two categories: communicable diseases and non-communicable diseases. Infectious diseases are diseases caused by pathogens (such as bacteria, viruses, parasites, etc.) and can be transmitted between people or between people and animals. They are contagious and epidemic. The main infectious diseases include tuberculosis, hepatitis B, influenza, etc. Most sexually transmitted diseases are also infectious diseases. For infectious diseases, cutting off any of the three links (source of infection, route of transmission, and susceptible groups) can stop the spread of infectious diseases. Non-communicable diseases refer to those diseases that occur due to damage, functional loss, or non-communicable diseases of body cells, tissues, or organs, such as cancer, injury, heart disease, etc. Non-communicable diseases may exist in any tissue or organ, are complex and diverse, and require case-by-case prevention, care or treatment. Paying attention to nutrition, daily routine, exercise and hygiene are the main ways to prevent diseases. Scientific research shows that people's psychological state, especially emotions, have a huge impact on physical health. Traditional Chinese medicine pays great attention to the relationship between "seven emotions" and diseases. Recent studies by many Western scientists have shown that it is "emotional factors" that greatly shorten human lifespan. I specifically found some articles related to psychology and health and moved them online directly. I hope they can be helpful to you. When disease strikes, proper treatment is essential to restore the body to health. Reasonable treatment includes drug treatment, improved diet, reasonable exercise, and more rest. After understanding the basic knowledge of medication, minor illnesses can be solved by taking medication by yourself, but you must read the medication instructions clearly to avoid excessive dosage and drug poisoning. Medications that have never been used before should be taken under the guidance of a doctor, and allergy testing should be done.
