Humans need to sleep in dark.

  Even artificial light is bad; I can't sleep with the TV on and prefer complete darkness.

    Best thing I ever did for my sleep was to cover my eyes. An eye mask is fine, but I just have a really soft pillow I lay over my eyes and top of my head. As a teenager I worked overnights in the summer (10pm-8am), and I learned early on that no light equals good sleep.
