Suppose we all go nocturnal?

What would happen if we changed our society to a nocturnal one?Factories and shops opened at 8pm and closed at 5am and we all go to sleep during the day? How drastically would it affect the population?

It would increase energy/electricity consumption.

This really isn’t a General Question.

I’ll wager, however, that depression and suicides would increase dramatically. There’s evidence that lack of sunlight can effect people emotionally – you might have heard of “winter blues” or “seasonal depresion.”

Diceman refers to Seasonal Affective Disorder, which has a classy acronym to help explain the symptoms.
