How Long Can You Sleep in a Car Before Suffocating?

[VanLeila]

Actually, sleeping in a car with the engine off won't cause suffocation. Here's some additional information: 1. Sleeping with the engine running: If you sleep with the engine and air conditioning on without opening the windows, there is a possibility of suffocation due to lack of air or death from carbon monoxide poisoning. As the air inside the car decreases, the concentration of carbon monoxide produced by the engine increases. The time it takes to cause death depends on individual constitution, but if left unattended for a long time, it can be fatal. 2. Car sealing: Most cars are not completely airtight, so there are usually places where air can pass through, and there's no need to worry too much. However, some cars have better sealing, which might lead to suffocation because the oxygen inside the car gradually decreases, resulting in hypoxia and potentially death.
