I heard a bit on a podcast over the weekend that amounted to: put your mind on a Paleo diet (so to speak). Dial down your brain prior to sleep (i.e., put down your handheld device, less light, less noise, etc.). Try to mimic the environment of your predecessors. Along the same lines, eat well (e.g., less caffeine), get some exercise, etc. A healthy you helps you get a healthy sleep.
