How to get health from the natural environment?

To understand the relationship between environment and health, we must first make clear the relationship between environment and people. Human beings are the inevitable product of the evolution of natural environment to a certain extent. The environment has created human beings, and human beings are constantly improving the environment in order to better adapt to it. Nature provides all the necessary means of life and production for human beings. Once the natural environment is destroyed by nature or man-made, such as pollution, the ecological balance of nature will be lost and human health will be endangered. Generally, there are three factors causing environmental pollution: chemistry, physics and biology.

chemical factor

Some elements or their organic and inorganic compounds enter the environment, and people will be poisoned when they touch them. Such as aluminum, arsenic, mercury, helium, phenol, benzopyrene and various pesticides.

Physical factors

Such as dust, plastics, radioactive substances, static electricity, electronic dust, radon, ozone, noise, etc., can directly or indirectly cause harm to the human body.

biotic factor

Such as viruses, bacteria, fungi, etc. have always been human pathogenic factors.

The pollution sources or pollutants formed by the above three factors can directly affect the secondary pollutants in the environment and human health. Not only do individuals suffer from it, but more importantly, it affects future generations.

Healthy survival is one of the basic rights of human beings. Turning over the history of human development is a history of human struggle against heaven, earth and disease. Today, for the sake of human health, people constantly use modern scientific knowledge to transform the environment and create a safe and comfortable family, social and natural environment. It aims to maintain the ecological balance of the whole space.

Regrettably, since mankind entered the "civilized world", there have been some shocking scenes. Due to overpopulation, cities have mushroomed, green vegetation has decreased in a large area, factories are everywhere, and polluted smoke and turbid water are discharged day and night; Mines are everywhere, full of dust; The rumble of the machine was deafening; When the vehicle is driving, the exhaust gas overflows; People rush about for their own lives all day, the pace of work is accelerated, and interpersonal relationships are tense. These objective beings are all physical and mental pollution and enemies of people's physical and mental health.

As far as the actual situation of each family's small environment is concerned, the degree of pollution and its impact on health are also worthy of attention. For example, every family member can unconsciously bring dust, bacteria or pesticides to his family through his hands, clothes and food in his daily activities. If someone smokes indoors, it will have serious adverse effects on the smoker himself, passive smokers around him, especially pregnant women. If you are a housewife, you will cause respiratory diseases by inhaling smoke, gas or carbon dioxide from the toilet. If aluminum cookware is used too much, it will lead to aluminum poisoning or iron deficiency diseases. Improper use of household appliances may be attacked by ultraviolet rays, radio waves and magnetic fields such as TV sets, tape recorders and electric fans. Pet owners should be careful. Some diseases of animals can be directly transmitted to humans, while animals themselves are often carriers and can be transmitted to humans at will. Of course, patients with tuberculosis, hepatitis and other infectious diseases or sexually transmitted diseases in their family members should always be vigilant.
