What to Pay Attention to When Sleeping in a Car with the Air Conditioning On
2 Answers
It is best to choose a relatively open area and leave the window slightly open when resting, because when the vehicle is stationary, carbon monoxide produced by the engine can enter the cabin. If the air is not circulating, the high concentration of carbon monoxide inside the car can be life-threatening. Also, be careful not to turn on the air conditioning when the car is cold-starting, as this can easily accelerate engine wear. Here is some relevant information about car air conditioning: The temperature of the car air conditioning directly affects the comfort of the passengers. If the air conditioning is set too low for a long time, it can easily cause the occupants to catch a cold. The compressor of the car air conditioning is directly driven by the engine, so turning on the air conditioning reduces engine power and increases fuel consumption. Generally, if the car experiences insufficient power while driving on the highway, you can choose to turn off the air conditioning to improve engine power.
I've slept in the car with the AC on a few times, and the biggest concern is the high risk of carbon monoxide poisoning. When the engine is running, exhaust fumes can seep into the car, and if the concentration exceeds safe levels, it can be fatal within minutes. I've seen similar accident cases, so I'm particularly vigilant. Always park in open, well-ventilated areas like roadside or open spaces, never in garages or enclosed spaces. Keep at least a small window cracked to ensure air circulation. Park on level ground, engage the handbrake firmly to prevent rolling or theft, and keep the keys nearby to avoid accidental locking. Limit the time to no more than half an hour, especially if children or pets are present, as it's even more dangerous. Check that the exhaust pipe isn't blocked—older cars pose higher risks—and ensure the engine doesn't overheat. Stretch and move around before driving again, prioritizing health. Consider using proper rest areas for safety, as life is priceless.
