Always Keep the Bathroom Light On When Sleeping in a Hotel

.

• Pest Deterrent: Nocturnal pests like cockroaches and certain bugs avoid light. Keeping a light source on keeps them hidden in drains or crevices rather than venturing out into the living space.

• Exhaust Fan Ventilation: In many hotel rooms, the bathroom light switch is tied to the ventilation fan. Keeping it on helps continuously clear out moisture, preventing humidity buildup and damp odors overnight.
