Doctor Shares Scientific Trick to Instantly Cool Down Your Hot Car This Summer. Here’s What to Do..

Here’s how it works: Open one of your car’s rear windows. Then, on the opposite side, rapidly open and close the front door. For example, if you roll down the window behind the driver’s seat, swing the passenger-side front door open and shut quickly multiple times.

The idea is to create airflow: the door movement forces the stale, stifling air out and pulls fresh and hopefully cooler air in.

“When you open and close the door, it sweeps out all the air already in the car,” Fry explains. That action creates a low-pressure zone that draws out the “hot, sweaty, horrible” air—via what she calls “bulk flow”—and replaces it with “nice, fresh, easy air” from outside.
