If the bathroom light is too bright, close the door more or use a dim night-light instead.
The Bottom Line
Leaving the bathroom light on in a hotel isn’t a secret safety rule.
It’s simply a practical trick that some travelers use to make nighttime navigation easier.
A faint glow can help you find the bathroom, see obstacles, and orient yourself in an unfamiliar room without turning on a bright overhead light.
But remember: darkness is generally better for sleep, so don’t use more light than you actually need.
The ideal solution is simple:
Keep the room dark, keep the path clear, and use just enough low-level light to safely find your way when you wake up.
