What kind of air is really healthy? Good air must be all kinds of nutrients (such as macro elements such as O, N and H) needed by human body. At the same time, harmful substances such as dust (such as PM2.5), bacteria, viruses and formaldehyde cannot exceed the standard. More importantly, there is an indicator that has been advertised in major scenic spots in the past decade-negative ion concentration.
According to the regulations of the World Health Organization, the concentration of negative ions above 1000 /cm3 can meet the basic needs of health, the concentration below 1000 /cm3 can be regarded as air pollution, and the environment with the concentration between 1000 ~ 1500 /cm3 can be regarded as a fresh environment. The Joint Committee of Atmosphere of the League of Nations also tells us that people need about 654.38+0.3 billion ecological negative ions every day, while our living room, office, entertainment places and other environments can only provide about 654.38+0.2 billion, or even less. That is the serious shortage of negative ions in our living environment.
What are the effects of different negative ion concentrations on human health? Negative ion concentration below 1000 /cm3 will lead to respiratory diseases, decreased immunity, fatigue and other health problems. Only when the concentration of negative ions is above 1000 /cm3 can we meet the basic needs of health. The negative ion concentration of 5000-50000 /cm3 can enhance human immunity and antibacterial ability; It can reach 50000-654.38+ 100000 /cm3, which can sterilize and reduce the infection of diseases. It can reach 65438+ 100000-500000 /cm3, which can improve the natural healing ability of human body and make many diseases incurable.
What are the real negative ions in nature? Negative ions are ions with one or more negative charges, which are called "negative ions"; There are many negatively charged ions in the air, but not all negative ions have the function of environmental protection and health. Different molecular components have different effects on the environment and human body. Dr Horikou, who is recognized as the "first person in negative ion research" and "the first person in ion medicine research", found through nearly 40 years' research that the macro elements in human body are carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, calcium, magnesium, sodium, potassium and chlorine, accounting for 95-0 of the total weight of human body. Among the negatively charged ions near the earth's surface where human beings live, nitric acid series ions [NO3-(HNO3) m (H2O) n] are the most important. Because all the elements in this molecular string are essential macro elements for human body, the chemical reaction of this molecular formula with various components in the body will eliminate harmful substances in the body and produce substances beneficial to human body. At the same time, such negative ions will not gather to form potential, electric field and discharge, which will make people feel electric shock. Such negative ions are truly environmentally friendly and healthy.
Therefore, in the case of good air, environmental protection and healthy natural negative ions must be indispensable.
