Light, Sound, and Temperature
Dim, warm lighting signals bedtime better than any resolution. Use blackout curtains if streetlights intrude, and aim for a cooler room, often between seventeen and nineteen degrees Celsius, to support deeper sleep. A simple white-noise source masks irregular sounds without demanding attention. Together, these tweaks reduce arousal and cue the brain to settle. Comment with your biggest obstacle—light leaks, noisy neighbors, or heat—and we’ll propose low-cost fixes tailored to your room’s quirks.
