What are the benefits of carbon dioxide for the human body?

Studies have shown that when the concentration of carbon dioxide in the air is less than 2%, there is no obvious harm to people, and more than this concentration can cause damage to human respiratory organs, that is, carbon dioxide is not a toxic substance under normal circumstances, but when the concentration of carbon dioxide in the air exceeds a certain limit, it will cause poisoning to the body, and high concentrations of carbon dioxide will suffocate people.

Animal experiments have shown that the higher the concentration of carbon dioxide in air with normal oxygen content (20%), the higher the mortality rate of animals. At the same time, pure carbon dioxide causes animal deaths, and lower oxygen causes more rapid deaths.

It is a non-toxic gas and is not harmful to the human body, but the human body will also feel uncomfortable in a high carbon dioxide and low oxygen environment for a long time, which is not because of the effect of carbon dioxide, but because the oxygen content is too low to cause insufficient oxygen supply to the human body.

Carbon oxide can be injected into beverages, increasing pressure, causing bubbles in beverages and increasing the taste of drinking, such as soda and beer. Solid carbon dioxide (or dry ice) vaporizes at room temperature, absorbing a large amount of heat, so it can be used for rapid food freezing.

Carbon dioxide is heavier than air and does not support combustion, so many fire extinguishers use their properties to extinguish fires by producing carbon dioxide. The carbon dioxide fire extinguisher is directly extinguished with liquefied carbon dioxide, in addition to the above characteristics, it has the advantage of not leaving solid residues after extinguishing the fire.

Carbon oxide can also be used as a shielding gas for welding, and its protective effect is not as good as other rare gases (such as argon), but it is relatively much cheaper.

Carbon dioxide can be used to make wine, carbon dioxide gas creates an oxygen-deficient environment that helps prevent bacteria from growing in the grapes, carbon dioxide controls the pH level, carbon dioxide is added to the pool to control the pH level, and carbon dioxide is added to keep the pH level from rising.

Carbon dioxide is a common gas in life, so what are the benefits and harms of carbon dioxide? Next, I will introduce it to you.

Benefits:

1. Carbon dioxide does not burn, and the density is higher than that of air, so carbon dioxide is usually used to extinguish fires.

2. Solid carbon dioxide directly turns into gas when it melts, and is often used as a refrigerant.

3. High pressure is used to dissolve more carbon dioxide, such as for the production of carbonated beverages, beer, etc.

harm

1. When the carbon dioxide content in the atmosphere increases to a certain extent, the temperature on the earth will rise, which is the "greenhouse effect".

2. The increase in carbon dioxide causes the sea level to rise.

3. Excessive inhalation of carbon dioxide will produce symptoms such as headache, chest tightness, fatigue, etc., and if this situation continues for a long time, coma, reflex loss, pupil dilation, blood pressure drop and even death will occur.
