It’s not an argument in favor, but a defense to an argument against. The reasoning goes that a lot of other things would be better served by being moved an hour earlier, even if school wouldn’t. That said, even for K12 students, I’d say it’s a give and take. Waking up and going out in the dark each morning does sound bad for mood and potentially for circadian rhythms. But school gets out at 3PM, and on the shortest days of the year, the sun sets around 5PM. That leaves only 2 hours to potentially spend outdoors in the sun, at best; after-school activities can easily consume much or all of that time, not to mention homework. Or even if you spend all day indoors, the earlier the sun sets, the sooner your body starts producing more melatonin and making you feel tired; robust artificial lighting can help, but then it’s harder when you are ready to start winding down for the day. And then there’s seasonal affective disorder (Google it). In all these cases, going from 2 to 3 hours of sunlight after school would be a big help.
