The book insulation tip is great and could be a good segue into replacing reading habits for actual books vs e-reader / other displays.

Even with "nightshift red colours" I could stay up reading for hours vs even with something very interesting to me in actual book form + warm secondary light source = getting sleepy and quickly so.

I'm guessing melatonin does get depressed significantly as soon as you start looking directly into a light source.
