How to Solve the Problem of Being Too Hot When Sleeping in the Car During Summer Road Trips?

You can turn on the air conditioning when sleeping in the car during summer. Safe ways to sleep with the air conditioning on in the car: Switch the air conditioning mode: When using the air conditioning in the car, switch from recirculation mode to fresh air mode. Do not keep the recirculation mode on for too long, as the air inside the car will gradually decrease, leading to an increase in carbon monoxide levels, which can cause poisoning. Adjust the air conditioning fan speed: Do not set the air conditioning to the lowest fan speed. If the air conditioning runs at low energy for a long time, dust from outside can be sucked into the air filter. If the fan speed remains low for an extended period, this dust will be difficult to blow out and may accumulate and mold, affecting health. Open the windows: Always leave the car windows slightly open, about 2CM to 3CM. The more windows you open, the better, but avoid opening them too wide to prevent potential security risks. If the car has a sunroof, it's best to open it slightly for better ventilation and air circulation. Avoid sleeping for too long: Try not to sleep in the car for extended periods, provided the first three steps are followed. If you really need to rest, set an alarm for 1 to 2 hours, wake up, and open the car doors to refresh the air inside.
Speaking of road trips, sleeping in the car during summer can be unbearably hot—I’ve learned this the hard way. Back then, I parked by the roadside, and the sun baked the roof, leaving me sweating profusely by midnight. My advice: first, park under a tree or in a shaded spot in a parking lot. Don’t close the windows completely—leave a small gap and use a mesh cover to keep mosquitoes out while allowing airflow. Bring a USB-powered mini fan that attaches to the window, or use sunshades to block the windows and reduce heat absorption. Keep some damp towels in the car to wipe yourself down for cooling, or invest in an affordable car-mounted misting fan. Also, check if the roof seals are worn or leaking, as heat can build up faster in hot weather. If your budget allows, installing a solar-powered exhaust fan is a great option—it runs on sunlight without draining your battery, perfect for long trips. Avoid sleeping with the AC on to prevent carbon monoxide poisoning—safety first. Wear lightweight cotton clothes and bring a sleeping bag to block the chill. In short, prepare multiple tricks and rotate them until you find what works for a good night’s sleep.
