Regulated sleep can cause CO2 poisoning if used incorrectly

Hot weather in Ho Chi Minh City makes the use of air conditioners popular.Ms. Nguyen Thi Hoang Trang shared the use of air conditioning for her child since birth: "Every night I sleep, I wear more long clothes for babies to avoid cold when using air conditioners.My room has a misting machine to avoid dry skin.Whenever my child has a sign of respiratory -related disease, I often have small salt water and take your baby to see a doctor.MSc Nguyen Hai Cong - Head of the Faculty of TB and Lung Diseases, Military Hospital 175 - Warning, the long -lasting air conditioning in the closed space can cause reducing oxygen, increasing CO₂ in the room, directly affecting the nervous and respiratory system.

Civil air conditioner usually only cools the air by sucking old air, cooling and blowing, without the function of gas exchange with the external environment."If staying in the air -conditioned room, the CO₂ concentration will increase due to respiration, while the amount of oxygen decreases.Cold and dry air from air conditioner can cause dry skin, mucosal damage and respiratory infections.Young children, with incomplete respiratory systems, skin and mucous membranes are vulnerable, especially easily affected.

"Let children lie in the cold room for a long time, especially when the temperature is low, can cause respiratory infections, pneumonia.Not to mention, if not cleaning periodically, dirt, bacteria, fungi in the indoor unit will spread out the room," the doctor noted.To use the safe air conditioner, the public doctor recommends: Do not place the temperature too low, avoiding the cold, dry air to damage the respiratory tract.Priority is given to air conditioning with fresh air exchange system or more ventilation fans.

Maintain moisture with a moisturizer or a pot of water, trees in the room.If there is no ventilation system, every 60 minutes should open the door for a few minutes for the air to circulate."Air conditioner is an effective tool to support in hot weather, but it is necessary to use knowledge to ensure health, especially for the elderly and young children," the doctor emphasized.
