Why shouldn’t you sleep in a car even with the air conditioner on?
According to information in the Health & Life newspaper, quoting Assoc. Prof. Dr. Dam Hoang Phuc, Hanoi University of Science and Technology , when the car is in operation, materials such as gasoline, diesel, and air will be burned and discharged. emits CO2 and unburnt fuel. That fuel will produce carbon monoxide (CO) .
CO is a gas that can cause blood poisoning, when the concentration of this gas inside the car increases and people inhale, CO binds to red blood cells and displaces oxygen, resulting in decreased oxygen in the blood.
Lack of oxygen causes suffocation, shock and, more seriously, death. This condition is called CO poisoning. If the car engine is not up to standard, causing the exhaust to leak will increase the risk of suffocation due to CO poisoning.
Even if the car’s engine is working properly, in a small space, air circulation inside and outside the car can be affected. And that amount of air will not be enough for a person to breathe in an enclosed space.
In particular, according to Assoc. Prof. Dr. Dam Hoang Phuc, the risk of causing asphyxiation when sleeping inside a running car will be lower than that of a parked car. During the move, through the ventilation slots, the air inside the car can be exchanged to the outside. But when the car is parked in closed areas and the car engine is still running, the oxygen inside the car will be gradually sucked up to serve the fuel combustion process.
Is it safe to roll down the car window?
Most people think that the act of lowering the car window will cause air to circulate and will help prevent suffocation and CO poisoning. But actually, according to Dr. Babu Shershad from First Medical Center (Dubai, UAE) , CO2 always accumulates inside the car to a lesser extent, even when the window glass is lowered. .
Therefore, after being exposed to CO for a period of time, even lowering the glasses will cause the amount of oxygen in the blood to decrease, the body will lose water and fluids.
Why is it possible to stay awake in the car but not be able to sleep?
According to information from the Malaysian Ministry of Health shared in Says newspaper , the common symptoms of CO poisoning are headache, nausea, dizziness, vomiting, chest pain, difficulty breathing, confusion, convulsions. . When inhaling large amounts of CO in a short time will make symptoms worse, leading to coma, loss of consciousness.
These symptoms are easier to recognize if you are in a sober state. When sleeping in a car, if unfortunately encountering CO poisoning, it will be extremely dangerous because it will not feel the signs and can cause death.

Never start the vehicle in an enclosed area, even if the car or garage door is open.
