Why Does Car AC Make Me Nauseous?

Some individuals may experience nausea when using the car's air conditioning system due to the swift changes in air pressure and temperature and the accumulation of bacteria and pollutants in the ventilation system.

To alleviate discomfort, there are several measures you can take:

1. Turn off the air conditioner and open the windows to introduce fresh air.

2. Take a short break and step outside the car to breathe in fresh air.

3. Stay hydrated by drinking ample amounts of water.

4. Rest and refrain from driving until you feel better.

If symptoms persist or worsen, it is advisable to seek medical attention from a doctor or contact a poison control center for guidance.

Is the car's AC system circulating fresh air or recirculating the same air?

The choice between car AC recirculation and fresh air mode involves either cooling the air inside the vehicle or bringing in outside air. Recirculation mode cools the air more quickly and helps save fuel, but it can result in impure and humid air inside the car.

Fresh air mode, on the other hand, reduces humidity and fogging while bringing in oxygenated air, but it can cause the AC to work harder and potentially affect fuel efficiency.

It is recommended to switch between the modes depending on the specific situation to optimize comfort and maintain air quality and fuel efficiency.
