NEED TO OPEN WINDOWS AND DOORS TO LET HOT AIR OUT AND WAIT A FEW MINUTES BEFORE ENTERING AND USING CAR AIR CONDITIONING,
According to research, a car's dashboard, seats, a/c ducts, in fact ALL of the plastic objects in your vehicle, emit Benzene, a toxin.
The "acceptable" Benzene level indoors is: 50mg per sq.ft. A car parked indoors, with windows closed, will contain Protected content of Benzene - Protected content the acceptable level.
If parked outdoors in the sun, at a temperature above 60 degrees F, the Benzene level goes up to Protected content , 40 times the acceptable level. People who get into the car, keeping the windows closed, will eventually inhale excessive amounts of the BENZENE toxin.
Benzene affects the kidneys and liver. What's worse, it is extremely difficult for your body to expel this toxin
So friends, please open the windows and doors of your car - give it some time for the interior to air out - before you enter the vehicle.
I have practiced the above technique for years - mainly because the interior of the car became cooler faster--- but now it makes even more sense /scents/ cents
