Will you die if you sleep in the car without opening the window?

If you don't open the window and sleep in the car, it's definitely not good, sometimes it's dangerous and in extreme cases it's fatal. This is indeed the case in life.

With the development of technology, the sealing performance of vehicle doors and windows is good now, and the narrow space in the car is also airtight. Even if it is parked in an open place with large outdoor air circulation, it is difficult to exchange air with the outside of the car without opening the window.

People constantly consume oxygen and exhale carbon dioxide. At the same time, the concentration of oxygen is getting lower and lower, and the concentration of carbon dioxide is getting higher and higher. When it reaches a certain level, such as about 6%, people are in danger of death from hypoxia and carbon dioxide poisoning.

Under the premise of "sleeping in the car without opening the window", you need to pay attention to the following points:

A, starting the external circulation mode of the air conditioner;

B, the car is parked in a place with good air circulation;

C, the temperature outside the car is not suitable for a long stay, such as direct sunlight, and the roadside temperature is high in summer.
