Should Car Windows Be Opened When the Vehicle Is Exposed to Sunlight in Summer?

After a car has been exposed to intense sunlight, it is generally advisable to open the windows for ventilation, as the evaporated formaldehyde can be harmful to health. Below are some key points regarding prolonged sun exposure for cars: 1. Purpose: Exposing a new car to sunlight accelerates the movement of formaldehyde molecules, helping to dissipate the residual formaldehyde gas inside the vehicle. This not only helps eliminate odors from the new car but also allows fresh air to circulate, significantly improving the overall air quality inside the vehicle. 2. Precautions: Avoid prolonged exposure to sunlight, as it can accelerate the aging of interior upholstery and may even release more harmful gases.
In summer, when my car has been exposed to the scorching sun, I usually roll down the windows. The interior feels like a steamer, and opening the windows allows the hot air to escape quickly, lowering the temperature inside. If I don’t open the windows and turn on the AC directly, it cools down slowly and consumes more electricity, making people feel dizzy and uncomfortable when getting in. High temperatures can also accelerate the aging of plastic and leather materials in the car, making the smell worse. I suggest that after parking under the blazing sun, first open the windows for ventilation for three to five minutes to let some of the heat escape before closing the windows and turning on the AC. This saves energy and protects the interior. Always choose a safe location to open the windows, such as parking in the shade or a parking lot, to avoid rain or dust entering the car. Excessive heat inside the car can cause discomfort or even heatstroke, so timely ventilation is good for your health.
In summer when the car is exposed to the sun, I prefer to leave the windows slightly open for ventilation. Keeping the windows tightly closed traps the hot air inside, causing the temperature to soar to 40-50 degrees Celsius, making it feel like stepping into a furnace when entering. Opening the windows allows for rapid air circulation and cooling, reducing the load on the air conditioning and saving fuel. However, I've noticed that if left open for too long, dust and insects can easily get inside, dirtying the seats, and rainwater may seep in during rainy days, potentially damaging electronic components. Nowadays, car seats can get uncomfortably hot in warm weather, and opening the windows can shorten the time needed to adjust to the temperature. If you skip opening the windows and rely solely on the air conditioning, the cooling effect is good but consumes more energy, which isn't eco-friendly. It's advisable to briefly open the windows to let out the hot air and then close them immediately, using sunshades as an additional measure. Remember that prolonged exposure to the sun can damage the interior, so regular protection is essential.
