Negative ions, like sunlight, are indispensable substances for human beings. It can promote the human body to synthesize and store vitamins, strengthen and activate human physiological activities, also known as "air vitamins", and its concentration is a sign to measure whether the air is fresh or not. When you are in places with more negative ions, such as beaches, waterfalls and forests, people will feel fresh-headed, comfortable to breathe and refreshed. However, in air-conditioned rooms, streets and other places with low negative ion content, people will feel poor breathing, chest tightness, dizziness, listlessness and so on.
At the same time, negative ions are also necessary to maintain the dynamic balance of the earth's life environment. Without negative ions, the atmosphere will be full of pollution and water will disappear automatically. Negative ion environment is the foundation of human survival and health.
Negative ions and environment and health
It has good health care and therapeutic effects on human body.
Activate cell metabolism
Antioxidant, scavenging free radicals in the body
It can turn the PH value of body fluids into alkalescence.
Improve immunity and natural healing ability, and make the body full of vitality.
It has a good purification effect on the air environment.
Eliminate harmful chemicals such as formaldehyde, benzene and ammonia.
Smoke, dust and odor elimination
Eliminate electromagnetic radiation
kill bacteria
In a fresh environment, there are more negative ions than positive ions, and positive ions and negative ions are in a certain balance. However, with the increasingly serious pollution of modern industry, the air is filled with a large number of positive ions, which leads to the collapse of ion balance and the decline of human function.
The World Health Organization (WHO) stipulates that the concentration of negative ions above 400 /cm3 can meet people's basic needs; Below 1000 /cm3, it can be regarded as environmental pollution. However, it is not optimistic that the concentration of negative ions is very low in closed rooms, offices, entertainment places and other indoor environments and car spaces, which can not meet the basic demand of 400 /cm3.
People need about 65.438+03 billion negative ions every day, but we spend about 80% of our time indoors, and we can only get about 65.438+02 billion negative ions, which is seriously unable to meet the needs of healthy breathing, which is also one of the important reasons for the low immunity and sub-health of urban people.
The secret of longevity in Bama village
Bama Village, Guangxi, a world-famous hometown of longevity, is full of centenarians. There are many incredible things here: a woman can still give birth at the age of 49, and a 97-year-old groom marries a bride of 9 1 year-old and lies down when she is sick. ...
What is the secret of longevity and health preservation in Bama Village? Bama has all four elements of human health: air, water, sunlight and magnetic field, which are the best in the world. Of these four elements, air is the most important. People can live for a few days without eating or drinking, but they will die of lack of oxygen in their brains after leaving the air for 5 minutes! Negative ions in the air are an important factor for human longevity. The content of negative ions in the air of Bama is 2,000 to 5,000 per cubic centimeter, which is called "natural oxygen bar", while the number of negative ions in the air of several Changshou villages is as high as 30,000 per cubic centimeter. In ordinary cities, the figure is about 1 000, and even less pitiful indoors, often even less than 1 000.
