Is it safe to sleep in a car with the air conditioning on?
1 Answers
If the air conditioning system is not set to external circulation mode, with car windows closed, and especially in a tightly sealed garage, it is strongly advised not to sleep in the car. This poses a significant risk of carbon monoxide poisoning, which can lead to severe personal injury. However, if the vehicle is parked in an open, unobstructed area with good ventilation, with the heater set to external circulation mode and both the driver and passenger side windows lowered by 1cm, short-term rest inside the car is possible. Below are the disadvantages of sleeping in a car: 1. Poor air circulation: The air inside a car is very limited. Staying in such an enclosed space for extended periods can lead to illness due to stale air. Without fresh air circulation, carbon monoxide can accumulate, which is extremely harmful to health. 2. Increased fatigue: Sleeping in a car often leads to back and neck pain due to the lack of proper seating and back support. 3. Damage to the car's engine: Keeping the engine idling with the air conditioning on for extended periods while sleeping can significantly harm the engine. This practice increases the rate of carbon buildup in the engine and also raises fuel consumption, as the engine is running without the car moving.
