Sleep in the dark

This is something that I've referred to before and frankly something that scares me. I've previously mentioned the importance of sleeping in the dark, but this report stresses how important it is:

I wonder, would light bouncing off of clouds and through my bedroom window be considered artificial light? I guess it's probably light pollution?

I too took your advice when you first mentioned it and am very careful to make my bedroom dark.

But...really? Moonlight is different from all other wavelengths of light? Firelight is? Primal man never woke during the night to feed the fire or check for wolves? We're not adapted to some intermittent light during the night?

Just thinking out loud...

We don;t have curtains on our bedroom windows-do you think that's a problem?
