>Timing of light and absence of light is critical - early morning light exposure greatly benefits people with SAD. Of course, you aren't getting that in either system; even in Standard time the sun doesn't actually rise in the early morning. You're still going to need the wake-up light either way. With permanent DST, you'll actually get more of a chance to witness the sun in general, as there's a greater span of time that it'll be available for use when you're allowed outside at the end of the workday. Up in the dark, home in the dark just flat out sucks for the 4 months of the year these conditions occur; minimizing the number of people who have to deal with that and minimizing the number of days they have to deal with that should be top priority.
