What are the effects of sleeping in a car?

If you sleep in the car for a long time with the windows closed, it is easy to suffocate due to lack of oxygen in the car, which can be life-threatening. Try to avoid sleeping in the car, especially for long periods. If you must sleep in the car, it is possible as long as ventilation is ensured. Remember to ventilate to ensure air exchange between the inside and outside of the car. Related introductions are as follows: 1. To sleep in the car, first ensure that the vehicle is parked in a relatively open and well-ventilated place. Then, try to open the windows slightly before sleeping to ensure air exchange between the inside and outside of the car. 2. For short-term sleep, you can turn on the air conditioning and internal air circulation to ensure basic ventilation. After turning off the engine, relying solely on the battery power cannot maintain long-term ventilation.
Sleeping in a car requires high vigilance for safety. If you start the engine for heating or cooling, the exhaust may accumulate deadly carbon monoxide—a colorless, odorless yet extremely hazardous gas, especially when sleeping in enclosed garages or confined spaces where poisoning risks soar. Additionally, tightly sealed windows and doors can lead to oxygen deprivation, causing dizziness or suffocation. Parking in remote areas heightens privacy exposure; I once nearly jolted awake from someone peeping or attempting to open a window at night. Now, I only rest at well-lit, populated spots like gas stations or parking lots. Safety is paramount—never overlook these risks. Endure slight discomfort rather than sleeping with the engine running, lock doors but maintain an escape route, and always verify environmental safety before resting.
Sleeping in a car is really unfriendly to the body. The seats are hard, and you curl up all night, waking up with back pain as if it's broken, and your neck is stiff, leaving you groggy and drowsy all day. Poor air circulation causes exhaled carbon dioxide to accumulate in the cabin, making breathing stuffy and uncomfortable—especially if you have asthma or allergies, which can easily trigger discomfort. I tried sleeping overnight once and woke up with a splitting headache the next day. It's recommended to crack a window slightly for ventilation and bring a pillow or neck pillow to support your body and reduce pressure points. Although the cramped space makes it hard to turn over, leading to light sleep, at least this can provide slight relief. Long-term sleep deprivation in a car affects both health and mental state, so avoid it if possible.
