Where to Put Your Bed in the Bedroom: What the Research Says About Door, Window and Wall
Key Takeaways The rules about where a bed should sit (solid wall behind the head, a clear view of the door) usually don’t come with a study that tests them. I didn’t find one. A German study found most people, given a paper floor plan, place the bed to…
Bedroom Noise at Night
At 3:40 a.m. the refrigerator downstairs clicks off, and the quiet that follows is so complete it sounds like something. You never heard the compressor running. You’d have told anyone the house was silent. Then it stopped, and you found out it had been…
Motion Lights at Floor Level
Key Takeaways At night, where a light sits matters as much as how bright it is. A light at floor level lands on the path, not in your eyes. Red isn’t a free pass. In two small lab studies, red light raised measures of alertness in people awake at…

Why You Never Sleep Well the First Night in a Hotel
