When it comes to sleep, the first night in a new place can feel like a cruel joke. You settle into bed, expecting sweet slumber, but instead, you toss and turn like a fish out of water. Welcome to the “first-night effect.” In unfamiliar surroundings, sleep quality plummets. Objective sleep onset latency (SOL) drags on, stretching your anticipation. You stare at the ceiling, wondering why you can’t just drift off.
The first night in a new place can turn sleep into a frustrating game of toss and turn.
Studies show that on that dreaded first night, people experience longer SOL and increased wake after sleep onset (WASO). It’s like your brain decides to stay on high alert. What’s up with that? According to researchers, one hemisphere of your brain is keeping watch, like a worried parent. Meanwhile, your body is stuck in a tug-of-war between wanting to sleep and being wide awake.
Sleep efficiency takes a nosedive, too. You might find yourself in light sleep—stage N1—more often than not. Instead of deep, restorative sleep, you’re stuck in that annoying half-asleep state, where dreams feel just out of reach. Meta-analyses confirm it: first-night sleep is generally lower in quality and quantity. Additionally, non-consecutive adaptation nights can help control for the recurrence of FNE, allowing for better sleep quality over time.
The second night? A whole different story. Your body seems to remember, settling in more comfortably.
But it’s not just a one-off experience. The first-night effect can creep back in during later visits to the same location, especially if you’ve been throwing your sleep schedule out of whack. Irregular sleep patterns make it worse. Young, healthy folks are no exception. They deal with this nonsense, too, waking up more frequently and feeling groggy.
