There are several reasons why it can be difficult to sleep in an airport. Airports are noisy environments with announcements, alarms, overhead lights, background music, talking, and other ambient noises that make it hard to relax. They are also crowded places with many people, carts, and other activities occurring. Additionally, the unfamiliar environment and disruption of normal sleep schedules due to traveling across time zones can negatively impact one's ability to fall asleep.
