I did candle-only lighting and no screens at all after sundown for a couple weeks as an experiment one time. Candles (ones that don’t smell like a chemical processing plant, anyway) are expensive, inconvenient, and kinda dangerous, and demands of modern life make it hard to keep up, but my life-long “night owl” tendencies were cured in a couple days.

Why can’t we sleep? Because we keep an on-demand world-class carnival in our houses, and light them up super-bright at night. If you describe what we do and how we live, the cause of the overwhelming majority of sleep issues in our society is obvious. It’d be very surprising if that way of living didn’t cause widespread sleep issues.
