How Dangerous Is It To Sleep In A Closed Room With Air Conditioning On? #vfacts, #thongnao, #dieuhoa, #suthatnonao, Turn on the air conditioner in a closed room reduces the oxygen concentration, increases the CO2 concentration, making people tired. This is information that is being widely shared in some beef noodle groups. According to the content of the article, most people mistakenly believe that air conditioners have the ability to circulate air from the outside in. Therefore, every time we turn on the air conditioner, we close the door to avoid wasting electricity. However, the air conditioner has no ability to circulate or blow air from the outside in. People who use air conditioners often feel tired and have headaches if they stay in an air-conditioned room for a long time. The real cause is due to lack of oxygen, which makes the body tired and the brain seriously affected. The author of the article placed a CO2 meter in the bedroom (with air conditioning) at 11 pm, and was horrified to find that the CO2 index reached 2000 ppm the next morning, while the standard CO2 density should be below 700 ppm. According to this article, there have been many studies showing that CO2 concentrations above 1200 will cause bone calcification, kidney failure, memory loss in adults or rickets, slow brain development in children. At the end of the article, this person recommends that there MUST be a convection fan installed independently to circulate air from outside into the room. Or if not, turn on a small fan in the room and open the door slightly so that the air can circulate better. The question is: is that true? Does turning on the air conditioner in a closed room cause fatigue and headaches? Is it MUST to have a convection fan or open the door slightly when sleeping in an air-conditioned room at night? In this video, we will analyze together.
