Here are the precautions to take when sleeping in a car on rainy days: 1. Ensure ventilation: No matter where you are, safety is paramount. Keeping the air flowing is crucial, and opening the windows slightly is a good option. However, be mindful of personal safety—opening the windows too wide might attract unwanted attention, so a small gap is sufficient to maintain airflow while ensuring safety. 2. Use the external air circulation mode: Some drivers prefer using the internal air circulation mode to maintain the car's temperature when the air conditioning is on. While this is generally fine, avoid using internal circulation when resting or sleeping. Instead, switch to external circulation with natural airflow and avoid turning on the air conditioning compressor if possible. 3. Choose the parking location wisely: When traveling, rest stops may not always be in ideal locations, and you might end up parking in a confined space. Small spaces can lead to carbon monoxide buildup, and underground parking garages, in particular, have poor air circulation and lower oxygen levels compared to open areas. Therefore, try to choose open spaces for resting and avoid parking on roadways or curves.
