How to Rest in the Car with Air Conditioning in Summer?

After getting into the car, first open the windows for ventilation. If the car has been exposed to the sun, do not start the engine immediately. Instead, open all four doors to allow toxic gases to dissipate. After starting the vehicle, turn on the fan but do not activate the air conditioning (do not press the A/C button). Let the fan blow out the contaminated air from the air conditioning system. After running the fan for natural air for 5 minutes, press the air conditioning button to turn on the cooling function. Keep the windows open during this process. To cool the car quickly, switch the circulation mode to "internal circulation."

I often drive out in the summer and take short naps with the air conditioning on during breaks, but safety always comes first. Make sure to park the car in a well-ventilated area, away from exhaust fumes, and never leave the engine idling in a garage or enclosed space, as carbon monoxide buildup can be dangerous. Setting the AC temperature to 26-28°C is most comfortable—avoid going too low to prevent catching a cold from drastic temperature changes. Crack a front window slightly for ventilation to prevent stuffy air inside. Limit rest periods to 15-20 minutes; exceeding this can lead to stiffness or chills. Using the auto mode on the AC is convenient, as the system adjusts fan speed and temperature automatically. If your car has an air purifier, turn it on for fresher air. I recommend drinking water before resting to prevent dehydration and using a sunshade to block harsh light for added comfort. Remember, for longer breaks, it’s safer to move indoors or to a shaded outdoor area.

When the hot summer arrives, I'm used to taking a nap in the car with the air conditioning on, but my main focus is personal comfort. Adjust the seat to a reclined position, set the temperature to around 25 degrees, and keep the fan speed at medium to avoid excessive noise. Choose a quiet and shaded parking spot to minimize the impact of external heat on the AC efficiency. If it's a new car, use the dual-zone climate control to set different temperature zones—for example, I often keep the front cooler and the rear slightly warmer. When resting, pull up the window shades or sun visors to block out strong light. The nap shouldn’t be too long; 20 minutes is enough to avoid back pain. Set a phone alarm to wake up and prevent idling the engine. Sipping some water and using a small pillow can make the nap more comfortable, while the AC’s eco mode saves fuel and is environmentally friendly.

During the hot season, I prioritize energy efficiency and environmental protection when resting in the car with the air conditioning on. I park under trees or shade structures to reduce the initial cooling load. After starting the vehicle, I quickly lower the temperature by setting the auto mode to 26°C and using the lowest fan speed to minimize power consumption. I avoid prolonged engine idling, as it consumes fuel and emits gases, keeping it under 10 minutes. When resting, I slightly open the windows for ventilation, which saves energy and ensures safety. Carrying a portable fan helps reduce reliance on air conditioning. I also prioritize health by avoiding excessively low temperatures to prevent heatstroke. This approach conserves resources and protects the environment.
