The habit of turning on the car's air conditioner as soon as you get in the car - terrible consequences that few drivers know about

According to car experts, when parked outside, especially in hot weather, the car is often closed. But even when parked indoors or in the shade, the car can accumulate 400-800mg of benzene, 8 times higher than the allowable level. If parked in the sun, at temperatures higher than 16 degrees Celsius, the benzene level can reach 2,000-4,000mg, 40 times higher than the allowable level.

Therefore, if sitting in a car with the windows closed, people will inhale benzene without knowing that this poison affects the kidneys, liver and bone tissue. Moreover, it takes a long time and is extremely difficult to eliminate these toxic substances from the body.

Regarding this issue, previously, researchers from the Brit organization and quoted by the British newspaper The Sun said that car air conditioning is poisoning users. According to the Spanish car manufacturer SEAT, hot air in the car will affect the driver's reaction time. Specifically, if the cabin is hot at 35 degrees Celsius, the driver's reaction speed will decrease by 20% compared to the temperature of 20 degrees Celsius.

Other research results also show that, before starting to cool the air, the air conditioner releases all the hot air, along with benzene - the most powerful carcinogen. Benzene is also toxic to bones, causes anemia and reduces white blood cells, causing leukemia. It can also cause miscarriage in women.

So the first thing when getting into the car, even if the driver doesn't notice any smell of hot plastic, open the windows for a few minutes and then turn on the air conditioning. And after starting the car, keep the windows open for a few more minutes.

In addition, turning on the air conditioner as soon as you get in the car makes the engine work too hard, affecting the lifespan of the accompanying equipment.

According to a mechanical engineer at a garage in District 11, you should not turn on the air conditioner before or at the same time as starting the car, it will consume a lot of battery power. In addition, turning on the air conditioner first cannot cool the cabin quickly, on the contrary, it takes a long time to neutralize the hot air inside, which has a negative impact on the system and accompanying equipment.

In terms of technology, the engineer also said: "When the car cabin is cool enough, we should prioritize the internal air intake mode. Because if we use outside air, the system will consume more power to run, to maintain the coolness of the cabin."

In addition, when driving in flooded areas, drivers should also turn off the air conditioning system to limit dirt from being caught in the fan, causing damage to the vehicle's air conditioning system.
