Why Do Shoes Adopt Negative Ion Technology?

Nowadays many Shoe material All adopt Anion Technology, so what is negative ion and why negative ions are used? technology What about it?

The charged particles formed by atoms losing or gaining electrons are called ions, such as sodium ion Na+. Charged atoms are also called ions, such as sulfate ions. Some molecules can also form ions in special cases. Negative ions are ions with one or more negative charges called negative ions, also known as anions. For example, the state of oxygen is generally anionic, also called negative oxygen ions.

The effects of negative ions on human body are mainly in the following aspects:

1. respiratory system: negative ions can promote the formation of nasal mucosa columnar epithelial cells, accelerate the ciliary movement of bronchial mucosa, promote edema regression, improve alveolar ventilation function, and improve blood oxygen saturation. Clinical results showed that inhalation of negative ions with a concentration of 30 minutes after inhalation, the lungs increased oxygen uptake by 20%, increased carbon dioxide by 14.5%, relieved spasm of bronchial smooth muscle, and promoted pulmonary function and alveolar secretion function of asthmatic patients to return to normal.

2. the nervous system: negative ions can penetrate the blood-brain barrier and enter the cerebrospinal fluid, regulating the function of the cerebral cortex to balance the excitement and depression. By mediating the level of endorphin and interferon in human pituitary, it plays a sedative and analgesic effect. It can reduce blood vessel tension and regulate the balance between sympathetic and parasympathetic nervous system functions.

3. cardiovascular system: negative ions expand the coronary arteries through nerve reflex and body fluid, increase the coronary blood flow, improve the function of the myocardium, adjust the heart rate, restore the blood vessel reaction and blood flow speed, relieve the angina pectoris and restore the normal blood pressure.
