Contents of environmental sanitation protection

Environmental health preservation mainly includes "natural environment and health", "living environment and health" and "indoor environment and health" People live in nature, and their physiological functions and pathological changes are constantly influenced by nature. In the struggle to actively transform and adapt to the natural environment, they guarantee and maintain the normal life activities of the body, that is to say, man and nature are an inseparable whole, that is, "man corresponds to heaven and earth." The so-called "correspondence" means that the movement changes in nature often directly or indirectly affect the human body, and the human body will inevitably undergo physiological adaptation or pathological reaction due to the influence of nature.

Generally speaking, clean and sufficient water, fresh air, abundant sunshine, good vegetation and quiet and beautiful landscape are all natural environments suitable for human survival. On the contrary, air pollution, water pollution and harsh geographical conditions have led to an increase in the incidence and mortality of some diseases. In real life, on the one hand, we should pay attention to protecting the natural environment, on the other hand, we can use high-tech means to improve the environment. For example, EME, an ecological energy crystal alloy, is the first new synthetic material in the world that can focus and directionally emit negative oxygen ions. EME has achieved the super function of static, orderly, persistent, homologous, focused and directional emission because of its inherent excellent collection. At present, the technology has passed the acceptance of the Ministry of Science and Technology, and has been successfully applied to the series of new products of "Jiashanshui Ecological Health Mattress" of Lunjia. About half of people's life is spent in the living environment, which often directly affects people's physical and mental health. Therefore, how to choose a house according to local conditions and create a scientific, reasonable, comfortable and clean living environment is very important to ensure good health and prolong life.

The house where you live is required to be sunny. 2. The air should be ventilated and the temperature should be appropriate to avoid humidity and pollution. To achieve these basic conditions, it is very important to choose the orientation of the building.

Secondly, the choice of residence should avoid unhealthy water sources and mineral deposits, avoid high-voltage lines, strong electric fields, strong magnetic fields and places with ultrasonic waves and radiation, and choose places with superior natural environment. To create an ideal indoor environment, we should pay attention to the following aspects: ① Adequate indoor light ② Appropriate temperature and humidity. ③ Natural ventilation
