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:

Artificial light at night disrupts cell division

Just 1 'pulse' of artificial light at night disrupts the circadian mode of cell division -- 1 of the body's mechanisms that is damaged in the development of cancer

I took your advice long ago, when you first mentioned it (or at least the first time I saw you mention it) because it made sense to me. I immediately saw good results. I drape a small piece of dark fabric over my digital bedside clock and get pretty close to total darkness - there's a tiny amount of bleed from around the door but no more than starlight on a moonless night.

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?

Regarding your problem with the bedroom window, Jana: Give me your address and I'll come over one night and look into it.

Freaky indeed. Any other studies that found similar results?
