The lamp in your living room is ruining your sleep — and you don't even know it.

Most people don't realize their overhead lights are tricking their brain into thinking it's still afternoon at 10pm. Cool white LEDs suppress melatonin for hours. Here's what I switched to — a sunset lamp. It shifts from warm amber to deep violet, exactly the way real evening light moves. I put it on every night around 7. No more lying awake. No more that wired-but-tired feeling. Your body already knows how to wind down. It just needs the right light to start the process.
