I still remember my first solo hotel stay — a new city, an unfamiliar room, and strange nighttime noises I wasn’t used to. That first night, I turned off every light, assuming total darkness was the best option. But I quickly found myself fumbling around later, wishing I’d left a small light on. Over time, and after many hotel stays, I realized there’s actually a smart reason why keeping the bathroom light on can be surprisingly helpful — even if it doesn’t seem logical at first.
After years of traveling, I’ve learned both the benefits and the downsides of this habit. Here’s why it can be useful, and what to consider before leaving that light on overnight.
Advantages of Keeping the Bathroom Light On in a Hotel
Avoiding the Midnight Stumble
Trying to navigate an unfamiliar hotel room in complete darkness can be a recipe for bruised toes and tripping over luggage. Leaving the bathroom light on creates a soft glow that helps you move around safely without turning on bright overhead lights. It works like a built-in night light, giving you just enough visibility to avoid accidents and find your way easily.

Reducing Anxiety in an Unfamiliar Space
Even if you enjoy traveling, hotel rooms can feel unsettling — strange sounds, hallway noise, elevator dings, or street traffic can be distracting at night. A small amount of light can make the room feel more comforting and less isolating, especially if you’re traveling alone or are a light sleeper. That faint glow can offer a subtle sense of security in a new environment.
Helping Your Body Adjust to New Time Zones
Unexpectedly, a soft light can also help when dealing with jet lag. When your internal clock is adjusting to a new time zone, a gentle light source can provide a sense of stability and ease your transition into a new sleep routine. It’s a small psychological cue that can make those first nights in a new location feel more manageable.

Convenience for Travel Companions or Kids
If you’re sharing a room with family, friends, or children, leaving the bathroom light on can make nighttime bathroom trips easier. Kids in particular can feel nervous in the dark, and a visible light helps guide them without waking others. It also prevents guests from fumbling for light switches and accidentally disturbing everyone.
A Small Safety Boost in Emergencies
While rare, emergencies can happen in hotels. If an alarm goes off or a quick exit is needed, even a dim light can help you orient yourself faster. That little bit of visibility can save precious seconds when it matters most — making it a simple but practical precaution.

The Downsides of Leaving the Bathroom Light On
It Can Disrupt Sleep
For some people, even a faint light can interfere with falling asleep or staying asleep. Light exposure can reduce melatonin production — the hormone responsible for sleep — which may make it harder to drift off or return to sleep after waking up. If you’re sensitive to light, this habit might do more harm than good.

Slight Increase in Energy Use
Leaving a light on all night does consume electricity, even if it’s minimal. If you’re environmentally conscious, this might bother you — especially since hotels already encourage energy-saving habits. While the impact is small, it’s still something to consider.
May Attract Bugs in Warm Climates
In some warmer or tropical regions, lights can attract insects — particularly in older hotels with small gaps or less airtight sealing. While modern hotels usually minimize this risk, it’s worth keeping in mind if you’re traveling in bug-prone areas.
Smarter Ways to Use Light in Hotels
If you like the idea of soft lighting but want fewer downsides, here are a few better alternatives:
Bring a Small Night Light
A portable night light is compact, inexpensive, and provides just the right amount of glow without being too bright. It’s a great travel accessory and gives you more control over brightness and placement.

Control Light with the Bathroom Door
Leaving the bathroom door slightly open — about a couple of inches — can soften and diffuse the light, making it less harsh while still offering visibility.
Diffuse or Dim the Light
If the bathroom bulb feels too bright, covering part of it with a towel or using a dimmer (if available) can reduce glare and create a gentler, more sleep-friendly glow.
For me, keeping the bathroom light on in hotels has become second nature. If you’re a light sleeper, adjusting the brightness or using a night light might be a better option. Either way, the next time you settle into a hotel bed, consider testing it out — that small glow might make your night more comfortable, safer, and surprisingly restful.
