The Japanese trick to cool your car's interior in 30 seconds without having to turn on the air conditioning.

We're in the midst of the first heat wave of the summer, and one of the places where it's most noticeable is inside our cars. Getting into our vehicles if they've been parked outdoors can be quite a challenge.

But there's a trick that allows you to quickly cool down your vehicle's interior temperature, without having to turn the air conditioning on full blast. You don't even have to start the car.

The trick, apparently invented in Japan, is described in a video on the TikTok account @chollometro, titled: "Cool your car in 30 seconds without air conditioning."

The trick is to roll down one of the car windows and keep the other three closed. Then, open and close the door on the side opposite the open window several times .

This system creates a crossflow that helps expel the hot air accumulated in the passenger compartment and replace it with cooler air. This can reduce the temperature by up to ten degrees and is achieved in just 30 seconds of operation.

In any case, the recommendation is to park the car in the shade , use elements such as sunshades, and cover areas that come into contact with the body, such as the seats or the steering wheel.
