Can negative oxygen ions improve respiratory diseases and increase vital capacity?

Negative oxygen ions have the most obvious effect on the respiratory system. This is because negative oxygen ions enter the human body through the respiratory tract, which can improve the vital capacity of people. According to the test, inhaling negative oxygen ions in the glass mask for 30 minutes can increase the amount of oxygen absorbed by the lungs by 2%, while the amount of carbon dioxide discharged can increase by 14.5%, so negative oxygen ions can improve and increase the lung function, and this principle can also alleviate the pain of asthma patients. In addition, negative oxygen ions can also improve the detoxification ability of the body, normalize hormone imbalance, eliminate adverse reactions caused by excessive histamine in the human body, and avoid allergic reactions and hay fever.
