Does Air on Planes Make You Sick?

The video addresses the misconception that airplane air is a breeding ground for germs due to recycled air. It explains that while planes do recycle air, they also introduce fresh air and use HEPA filters, similar to those in hospitals, to remove bacteria and viruses. The air is recirculated multiple times per hour, and airflow patterns minimize the spread of germs. The risk of catching a disease is more related to proximity to other passengers rather than the air quality. The video concludes with a call to action for viewer engagement and briefly touches on the topic of sensitive teeth.
