How long can you sleep in the car with the air conditioning on?

[StErin]

It is recommended not to exceed 1 hour when sleeping in the car with the air conditioning on. The following precautions should be noted when sleeping in the car with the air conditioning on: 1. Ventilation: Many car owners worry about safety, but you can choose to open a small gap to allow air flow. 2. Maintain air circulation inside the car: If it is really hot and you must turn on the air conditioning, the air inside the car should be refreshed in time. You can open several windows to a width of two to three fingers to maintain some air circulation inside the car. 3. Try to park the car in an open area: Due to the special nature of their profession, many drivers often need to rest in the car, but the location is not fixed, sometimes even in underground parking lots. However, in a confined environment, carbon monoxide is more likely to accumulate, so it is important to choose an open and spacious environment for rest. 4. Regularly check the exhaust pipe: Remember to regularly check the exhaust pipe. If the carbon monoxide emitted by the vehicle leaks into the car, it can easily accumulate and cause poisoning. If the exhaust pipe is damaged, exhaust fumes are more likely to enter the car.
