I would sleep with my curtains open more often but I generally find the sodium street lights to be an annoyance when my eyes adjust to the almost darkness. At which point they get closed. I regularly go camping and have to agree with everything the author says. The physical exertion (setting up camp, building a fire, walking around etc) lack of environmental controls and natural light certainly correct any day / night in balance immediately. Though, since I finished University I have found that just having to get to work for 9am each morning takes care of most problems. Other than the occasional nights bad sleep, usually caused by being fascinated by some programming problem or even a real life issue!
