What are the dangers of turning on the air conditioning immediately after getting in the car?

The dangers of turning on the air conditioning immediately after getting in the car are as follows: 1. Heatstroke: Closing the windows and turning on the air conditioning right away can easily lead to heatstroke. A car with closed windows is a sealed space, and after being exposed to the sun, the hot air and exhaust gases inside are difficult to dissipate, and there is less oxygen. 2. Health hazards: High temperatures can trigger the release of pollutants from various sources inside the car, such as benzene and formaldehyde, which are harmful to health. Under the sun's exposure, the temperature inside the car can rise sharply, even higher than the surrounding temperature. 3. Increased fuel consumption: The temperature inside the car will take a long time to decrease, and it also consumes more fuel, making it not worth the effort. The engine has not yet reached its optimal state when the car is just started.
I noticed many people habitually turn on the air conditioning immediately after getting in the car. This increases the burden on the compressor, especially when the engine temperature is still low right after startup. The AC cooling efficiency is poor at this stage, and forcing the compressor to work can lead to premature wear and shortened lifespan. If the cabin air filter is dirty, dust and bacteria will be blown out immediately, affecting respiratory health. Long-term operation like this may cause the system to start and stop frequently, leading to increased fuel consumption, which is particularly noticeable during urban traffic congestion. It's recommended to open the windows for ventilation for a few minutes first, allowing hot air to escape and the interior temperature to drop slightly before turning on the AC. This protects the equipment while achieving quick comfort. Remember to check the filter regularly - replacing it annually can reduce odor issues. Developing this habit will also make your car more durable.
I always remind myself not to press the air conditioning button immediately after getting in the car. After being exposed to the sun, the air inside the car is stuffy and smelly, and turning on the AC will blow dust and mold everywhere. For people with respiratory issues, this can easily trigger coughing or allergies. I've noticed that bacteria accumulate inside the air conditioning system over time, and starting it without cleaning is equivalent to inhaling harmful substances. When it's hot in summer, I usually open all the windows first, let the car run for a minute or two to release the hot air, and then turn on the AC, setting it to balance between internal and external circulation. This is not only healthier but also cools the car down much faster. I'm especially cautious about this habit when children are in the car.
