If you’ve ever traveled and struggled to sleep in a hotel room, you’re not alone.

New beds, unfamiliar noises, and strange surroundings can disrupt even the best sleepers.

But here’s a simple trick that helps many travelers:
👉 A night light.

While some people swear by total darkness, others find that a soft, gentle glow makes them feel safer, calmer, and more at ease.

So why does such a small detail make such a big difference?

Let’s explore the science and psychology behind why a night light can actually improve sleep quality — especially in unfamiliar places.

🧠 The Science of Sleep in Unfamiliar Environments

Even if you’re exhausted, your brain may stay partially alert when you’re in a new place.

This is called the “first-night effect” — a well-documented phenomenon where:

• One hemisphere of the brain remains more active during sleep
• You experience lighter sleep and wake more easily
• You’re more sensitive to sounds and movement

✅ It’s an evolutionary survival mechanism — your brain is “on guard” in unfamiliar territory.

A night light can help reduce this alertness by making the environment feel more predictable and safe.
