Bedroom windows are a sleep hygiene problem for anyone who doesn't plan to wake up at dawn year round. I've installed blackout curtains as I moved, but they don't work all that well.

Yeah I live in a virtually windowless bedroom because of noise, light, and air pollution problems making me block off the windows.

Whenever I need sun I go outside. Or usually I’m at work where there are massive windows and great views of the city.

Huh, just use external blinds? They are installed in most houses in Germany and work very well. Also good three pane windows cut down noise enormously

Huh? They are expensive, hard, if not impossible to install in many places in the world that are not Germany, and not an option if you rent?
