In my mind, there are many tall and lush green trees in the forest. The sun shines through the cracks in the branches. There are many novel species, large beasts and fresh air that goes deep into my heart. In this increasingly prosperous city, the air is filled with the smell of tail gas. The smog some time ago and the earlier sandstorm are warning us of something. Want to breathe the fresh air of nature has become a luxury of modern people.
Why do people feel relaxed and comfortable when they enter nature? What good is he to mankind? How to build a "forest" equivalent to nature without going deep into the forest? Many questions have come, so I will introduce them to you one by one.
First of all, why do people feel relaxed and comfortable after entering nature?
It turns out that our air contains something called air negative ions. Air negative ion, also known as negative oxygen ion, refers to oxygen ion with negative charge and electron number of 1 or above. The main components of air are nitrogen (78%), oxygen (2 1%) and carbon dioxide (0.03%). Nitrogen has no affinity for electrons, only oxygen and carbon dioxide have affinity for electrons, but the oxygen content is 700 times that of carbon dioxide. Therefore, most of the negative ions produced in the air are negative oxygen ions in the air. It is formed by combining oxygen molecules in the air with free electrons. In forest air, the concentration of negative ions can be as high as 10000 /cm3, while in urban air, there are only a few hundred or even only positive ions.
Secondly, what benefits does he have to mankind?
Simply put, what are the benefits of negative air ions in the natural air to human beings? Negative ions have excellent effects of purifying and removing dust, reducing the harm of second-hand smoke, improving the prevention of respiratory diseases, improving sleep, resisting oxidation, preventing aging, scavenging free radicals in the body, and reducing blood viscosity. They enjoy the reputation of vitamine milk, air vitamin, longevity factor and air vitamin in the medical field. In addition, there are literatures about the treatment and clinical trials of negative ions on asthma, cardiovascular and cerebrovascular diseases, insomnia, etc.
Finally, how to make negative ions equal to nature without going deep into the forest?
Nowadays, the negative ion generators on the market can generate high-concentration negative ions, which creates conditions for people to have healthy air.
