The effects of negative oxygen ions on the respiratory system are very significant. They enter the human body through the respiratory tract and can increase a person’s lung capacity. Experimental results show that when a person inhales air containing negative oxygen ions through a glass mask for 30 minutes, the amount of oxygen absorbed by the lungs can increase by 2%,
while the amount of carbon dioxide expelled can increase by 14.5%. Therefore, negative oxygen ions can effectively improve and increase lung capacity, have a significant regulatory effect on respiratory function and the bronchi, and can noticeably improve the strength of respiratory muscles and lung ventilation function.
