Most of the free electrons generated by the ionization of molecules in the air under the action of high pressure or strong rays are captured by oxygen. One type of negatively charged (electrons are negatively charged) oxygen ions that thus gain some electrons is called a "negative oxygen ion."
Negative oxygen ions are known as "air vitamins" and can affect the physiological activities of the human body through the human nervous system and blood circulation.
Anions have the following main effects on the human body:
1. It affects the nervous system, which can strengthen the cerebral cortex function and mental activity, invigorate the spirit, improve work efficiency, and enable Sleep quality improves. Negative ions can also strengthen the oxidation process of brain tissue, allowing the brain tissue to obtain more oxygen.
2. It affects the cardiovascular system. According to the observations of scholars, negative ions can significantly expand blood vessels, relieve arterial vasospasm, and achieve the purpose of lowering blood pressure. Negative ions are also very beneficial to improving heart function and improving myocardial nutrition, which is beneficial to the condition of patients with hypertension and cardiovascular and cerebrovascular diseases. recover.
3. It affects the blood system. Research has confirmed that negative ions can slow down the blood and prolong the coagulation time, increase the oxygen content in the blood, and facilitate the transport, absorption and utilization of blood oxygen.
4. Negative ions have the most obvious impact on the respiratory system. This is because negative ions enter the human body through the respiratory tract, which can increase people's lung capacity. Someone once tested that inhaling negative air ions in a glass mask for 30 minutes can increase the amount of oxygen absorbed by the lungs by 2%, and the amount of carbon dioxide discharged can increase by 14.5%. Therefore, negative ions can improve and increase lung function.
