Many people experience difficulty sleeping in new environments, a phenomenon known as the first-night effect. This issue is not unique to any one person, as numerous studies have confirmed its existence. A sales director who travels frequently for work has reported struggling with this effect, taking longer to fall asleep and waking up more often.

At home, he averages seven hours of sleep, but in new locations, he gets significantly less. Further information on the first-night effect, including its evolutionary roots, can be found through the Associated Press, as reported in the Odessa American.
