It may sound like a quirky habit, but hanging a towel on your bedroom doorknob before going to sleep can bring unexpected advantages. Home and lifestyle experts note that this simple action can offer the following benefits:

1. Improves Humidity in Dry Rooms
   A slightly damp towel can help increase moisture in the air, reducing dryness that leads to sore throat, dry skin, or cracked lips during the night.

2. Helps Block Light or Drafts
   A towel draped over the doorknob can minimize hallway light seeping into the room or reduce small drafts that disturb sleep.

3. Absorbs Odors and Freshens the Room
   Clean towels naturally absorb lingering smells, helping maintain a fresher sleeping environment.

4. A Simple Safety Signal
   In shared living spaces, a towel on the doorknob can quietly signal to others that you’re resting and prefer not to be disturbed.

While not a widely known practice, this small bedtime trick may enhance comfort and sleep quality — especially in homes with air-conditioning, low humidity, or shared spaces.
