What should be paid attention to when sleeping in a car?

Here are the precautions to take when sleeping in a car: Avoid sleeping in poorly ventilated parking lots: First and foremost, ensure good air circulation. If the environment has poor air circulation and the car is left idling while sleeping, carbon monoxide produced during idling can accumulate and cannot be discharged. If it enters the car, it may lead to carbon monoxide poisoning, with unimaginable consequences. If you must sleep with the air conditioning on, be sure to do so in a well-ventilated area. Do not use the air conditioning in recirculation mode: In addition to avoiding sleeping in enclosed spaces, it is also important to pay attention to the air conditioning's recirculation and fresh air modes, which is a detail often overlooked. The fresh air mode draws air from outside the car, cooling or heating it before circulating it inside the car. The recirculation mode, however, cuts off the exchange with outside air, simply recirculating the air inside the car.
