Light, Sound, and Visual Noise
The room's sensory load often matters more than decorative theory when sleep quality is poor.
Focus on comfort, rest cues, and lower stimulation rather than rigid fear-based rules.
Learning Checklist
-
Soften late light
Reduce harsh brightness before sleep.
-
Lower sound clutter
Handle recurring noise sources instead of normalizing them.
-
Hide unfinished work
Do not let the room double as a to-do list.
