Can You Die from Sleeping in a Car with the Windows Closed?

[IkerLee]

Sleeping in a car with the windows closed can indeed be fatal. Here are the reasons: 1. In a sealed vehicle, the oxygen supply is limited. As a person sleeps, they continuously consume oxygen without fresh air replenishment, leading to hypoxia, suffocation, and potentially death. Additionally, most car interiors are made of PVC (polyvinyl chloride) derived from petroleum, and the adhesives used contain formaldehyde. In an enclosed space, occupants are prone to dizziness. 2. If the air conditioning is running, the car produces significant amounts of carbon monoxide. The concentration of carbon monoxide increases over time, exceeding safe levels within approximately 20 minutes, causing noticeable suffocation symptoms.
