WRT "Wake-Up Light With Colored Sunrise Simulation, White" and other technological gadgets, I've a hypothesis that some people actually wake up at sunrise (like an anti-vampire I guess?) and other people do pure internal clock. Furthermore part of my hypothesis is there is a strong correlation between those types and likelihood of SAD-diagnosis.
There are implications beyond SAD, such as alarm clock design. For example I can completely decouple from light input and sleep thru bright sunlight on my face if I'm tired (or drunk or hungover as I occasionally was in my youth). In fact many a time in my youth on weekends I'd come home around sunrise and fall asleep no problemo. If I used an alarm clock that simulated sunrise, I suspect I'd come into work late very often. On the other hand for SAD sufferers is the experience literally like a lightswitch like the sun rises and you are like biologically forced to wake up? If so they'd do very well indeed with a techno-gadget like this.
