In which way does electric lighting affect sleep? If you turn the lights off, no current flows so there’s not even any slight EM radiation to worry about. It’s just inert materials at that point, isn’t it?

Now that you brought up EM radiation, let me tell you what has been hidden from you:
Detailed discourse on the hazards of EMF, and a chance to buy my unique solution.
Nah. I’m just fucking with you. Not everyone on the Internet is nuts - only most of us.
But when light bulbs were invented, they were incandescent and much redder and dimmer. If you burn them too hot, the filaments would melt. Therefore there wasn’t much blue light if any released by early light bulbs
But electric lights would still have imitated daylight better than candles or gas lights, and human biology responds to what time of day or perceives itself to be in.

Exposure to blue light affects sleep rhythm.

Indeed.
But electric lights would still have imitated daylight better than candles or gas lights, and human biology responds to what time of day or perceives itself to be in.
