How to Sleep in a New Place (and Beat the First-Night Effect)

You’re finally on holiday, or staying somewhere lovely — and you sleep terribly. Tossing, waking at every unfamiliar sound, watching the ceiling of a strange room. If your worst night’s sleep often happens on the first night somewhere new, there’s a real, fascinating reason for it. Here’s what’s going on and how to sleep better in any unfamiliar bed.

The First-Night Effect Is Real

Scientists call it the “first-night effect,” and research has revealed something remarkable: when you sleep in a new environment, part of your brain stays partly alert, keeping watch. Studies found that one hemisphere of the brain remains more vigilant and wakes more easily on the first night in an unfamiliar place — essentially a built-in “night watch” left over from our ancestors, whose survival depended on staying alert to danger in unknown surroundings. For a wider look at the underlying science, see published guidance.

The good news: it’s completely normal, it’s temporary, and your sleep usually improves noticeably by the second or third night as your brain decides the new place is safe.

How to Sleep Better in a New Place

You can’t fully switch off that ancient vigilance, but you can reassure your brain and recreate the comfort of home.

Bring familiar cues. Your brain relaxes with the familiar. Pack your own pillow or pillowcase, and use the same sleep sounds (a white-noise app), a familiar scent (a pillow spray or the pillowcase from home), and — importantly — your usual bedtime routine. These signals tell your brain “this is normal, you’re safe.”

Control the environment. Make the space dark, quiet, and cool: close the curtains (or pack an eye mask), use earplugs or white noise to mask unfamiliar sounds, and adjust the temperature. Blocking out the “new” sensory input calms the vigilance.

Keep your schedule and wind-down. Stick to your normal sleep and wake times as much as possible, and don’t skip your wind-down just because you’re away. Familiar timing and rituals ground your body clock.

Go easy on travel temptations. Extra alcohol and caffeine are common on trips but sabotage already-fragile sleep. Keep them in check, especially close to bedtime.

Relax the watchfulness. Because the first-night effect is about alertness, calming techniques help — slow breathing, a body scan, or muscle relaxation reassure your nervous system that it’s okay to fully switch off.

For Hotels and Travel Specifically

Ask for a quiet room away from lifts, ice machines, and busy roads. Block the light from gaps in curtains and glowing electronics (a clip or an eye mask works). And if you’ve crossed time zones, remember jet lag is layered on top of the first-night effect — getting onto local time and using light strategically helps both.

When It’s More Than the First Night

The first-night effect fades after a night or two. If you consistently can’t sleep anywhere — home or away — or your sleeplessness is driven by ongoing anxiety, that’s a different issue worth addressing with good sleep habits and, if it persists, a chat with your doctor.

The Bottom Line

Sleeping badly your first night in a new place is your brain doing its ancient job — keeping half an eye open in unfamiliar territory. It’s normal and passes within a night or two. Ease it by bringing familiar cues (your own pillow, sleep sounds, routine), controlling light and noise, keeping your schedule, and using relaxation to calm the watchfulness. Do that, and even a strange bed can feel restful — fast.

Frequently Asked Questions

Why can’t I sleep the first night in a new place?

It’s called the first-night effect: research shows part of your brain stays more alert in unfamiliar surroundings, like a built-in “night watch” for safety. This makes your first night’s sleep lighter and more broken. It’s normal and usually improves by the second or third night.

What is the first-night effect?

The first-night effect is the tendency to sleep poorly the first night in a new environment because one hemisphere of the brain stays partly vigilant to monitor the unfamiliar surroundings. It’s an evolutionary survival mechanism that fades as you acclimate.

How can I sleep better in a hotel?

Bring familiar cues like your own pillow, sleep sounds, and bedtime routine, and control the environment with an eye mask, earplugs or white noise, and a cool room. Request a quiet room, block out light, and keep your usual schedule.

How long does it take to sleep well in a new place?

Usually just a night or two. The first-night effect is strongest on the first night and fades as your brain decides the new environment is safe, so sleep typically improves by the second or third night.

Does bringing my own pillow really help me sleep away from home?

Yes, it can. Familiar cues like your own pillow, a familiar scent, and your usual routine reassure your brain that the environment is safe, which helps quiet the vigilance behind the first-night effect.
