Why Do Humans Get Sick When They Travel?

Airplane sickness is when people get sick after flying because of the close quarters and recycled air. When you’re stuck next to someone who has a cold, that germs can easily spread through your nose or mouth. It’s like sharing a pillow with someone who’s sneezing, except now it’s the whole airplane.
