Why the First Night in a New Place Often Cuts Your Sleep Short

A tech-sales director reports losing about two hours of sleep on his first night away, illustrating the first-night effect that scientists have documented for decades. Studies highlighted by Anna Wick of the University of Freiburg and Ahmad Mayeli of the University of Pittsburgh show the brain remains partially vigilant in unfamiliar surroundings, cutting total sleep by roughly 20-30 minutes and reducing deep-sleep activity.

The effect is most pronounced in children, adolescents and seniors, and heightened anxiety can intensify it. Additional factors such as travel stress, unusual hotel lighting or strained relationships may also disrupt rest, though some travelers sleep better if they are exhausted. Sleep-hygiene recommendations—including cool, dark rooms, consistent bedtime, familiar items, and calming visualizations—can help, and arriving a day early is suggested for critical meetings.
