We humans aren't supposed to be up at night.... if it were natural we'd be able to see in the dark like a cat lol.
I've only had to work nights a few times doing highway construction..... when I was younger it sucked but I made it work.... now in my mid 40's I can't do it anymore.... I don't see as good, reaction times aren't as good (we operate heavy equipment), I told the office last year no more..... get someone else.
