Why Does Any Car AC Make Me Feel Nauseous and Dizzy?


Many people enjoy the cool and refreshing breeze of a car air conditioning (AC) system, especially during hot summer days. However, for some individuals, the experience of riding in a car with the AC on can be quite unpleasant. They may feel nauseous and dizzy, which can significantly affect their comfort and overall driving experience. In this article, we will explore the possible reasons behind these symptoms and discuss potential solutions.

1. Air Quality

The air quality inside a car is influenced by various factors, including the cleanliness of the AC system itself and the environment in which the vehicle is driven. Dust, pollen, and other allergens can accumulate in the AC system if not properly maintained, leading to poor air quality. Breathing in contaminated air can cause respiratory discomfort, which may manifest as nausea and dizziness.

2. Temperature and Humidity

While the AC helps cool the air, it also reduces the humidity level inside the vehicle. Low humidity levels can lead to dry throat and nasal passages, causing discomfort and potentially leading to feelings of nausea and dizziness. Additionally, sudden changes in temperature, such as entering a cold car on a hot day, can also trigger these symptoms.

3. Motion Sickness

Some individuals are more prone to motion sickness than others. Motion sickness occurs when there is a disconnect between what the eyes see and what the inner ear senses. The up and down motion of a vehicle, coupled with the cool airflow from the AC, can exacerbate feelings of motion sickness, leading to nausea and dizziness.

4. Chemical Odors

Certain vehicles or AC systems may emit chemical odors, especially if they are new or have not been properly cleaned. These odors can be irritating to some people and may trigger symptoms such as nausea and dizziness. The intensity and type of odor can vary, and individual sensitivities also play a role in the body’s response.

How to Reduce Nausea and Dizziness in a Car with AC

Now that we understand some of the reasons why the car AC can make people feel sick, let’s explore some strategies to alleviate these symptoms:

1. Maintain Good Air Quality

  • Regularly clean and replace the cabin air filter to ensure fresh and clean air circulation.
  • Avoid driving in areas with high levels of air pollution or dust.
  • Use an air purifier or ionizer designed for vehicles to improve air quality inside the car.

2. Gradually Adjust Temperature

  • Avoid abrupt temperature changes. Instead, gradually lower or increase the temperature when entering or leaving the car to allow your body to adjust.

3. Use Recirculation Mode

  • Switch the AC to recirculation mode to minimize exposure to outdoor pollutants and allergens.
  • However, it is essential to periodically switch to fresh air mode to prevent excessive carbon dioxide buildup inside the vehicle.

4. Ventilate the Car

  • If the weather permits, open the windows for a few minutes to allow fresh air to circulate inside the vehicle. This can help reduce stuffiness and improve air quality.

5. Avoid Focusing on Moving Objects

  • When feeling nauseous, try to avoid focusing on objects outside the car that may be moving rapidly. Instead, look towards the horizon or a fixed point to help stabilize your inner ear and reduce motion sickness.

6. Take Breaks

  • If you frequently experience nausea and dizziness while driving, take breaks during long journeys to give your body time to rest and recover.

7. Avoid Strong Odors

  • If you notice strong chemical odors or scents from your car or the AC system, consider having it inspected and cleaned professionally. Driving with the windows open can also help disperse any unpleasant odors.


Feeling nauseous and dizzy in a car with the AC on can be a distressing experience. By understanding the factors that contribute to these symptoms, such as air quality, temperature, motion sickness, and chemical odors, individuals can take steps to reduce and prevent discomfort. Following the tips mentioned above can help create a more pleasant and nausea-free environment inside the car, allowing for a more enjoyable driving experience.
