You already know screens before bed aren't great for sleep. And yet — here you are. Scrolling at 10pm. Watching one more episode. Answering a few last messages. Not because you don't care about sleep. But because that final hour is the only quiet moment you get all day.
The problem isn't that you're using screens. The problem is the light signal those screens — and your lamps, your TV, your bathroom LEDs, your kitchen lights — are sending to your brain at exactly the wrong time of night.
For most of human history, when the sun went down, the world got dark and warm. Firelight. Candles. Low, amber light that told the body: the day is ending. Your body still expects that signal every single night.
- Feel exhausted on the couch
- Get into bed
- Suddenly feel wide awake
- Lie there for 30, 40, 60 minutes
- Wake up groggy and wonder why
You're not bad at sleeping. Your evening light environment is sending your brain the wrong signal at the wrong time. This isn't a discipline problem. It's an environment problem.
