Having "suffered" from this "syndrome" my whole life I can tell you that it isn't "caused" during adolescence any more than people "turn gay" in their teens. About 1 in 15 people have this "disorder" -- only it is not a disorder, it is a specalized social function. The articles above talk about the difficulty people with DSPS have operating within "societal norms". Right-- because they aren't supposed to. All social species have specialized groups for specific functions. The purpose and function of "night people" seems pretty obivious to me: night people tell the bedtime stories to the rest of the tribe, we watch the fire and keep the wolves at bay, we paint the magical animals in the dark end of the cave for the shamen. Night people perform the mystery plays after dark. Night people are the artists, storytellers, bonfire-builders, festival organizers, and night-watch. The "normal" people depend on the night people for the entertainment and magic that creates the cultural glue that keeps the tribe together, and they depend on the night people to watch over them while they sleep.

Date: 2004-10-06 09:23 pm (UTC)Syndrome or not, it can be a real bastard. Naming it as a syndrome is misleading however. Back when I took neuropsych we studied a lot of sleep related disorders, and in fact between 1 in 5 and one in 15 (depending on the region) people have a diurnal rhythm that is nocturnal and no amount of drugs or therapy will reverse it.
I myself suffer from this, and have had to take large measures in my life to control it.
It does tend to be genetic. So I’m not surprised that it hit me. Both my mom and dad and grandparents on both sides were nocturnal, and photosensitive.
You are right, there is an evolutionary basis for this. In primitive times a certain percentage of the population would have been required to stay guard, hunt or co9nduct other activities at night. Those of us who have DSPS are not “ill”, wer are just optimized for different activities than the mainstream person.

Date: 2004-10-07 08:39 pm (UTC)I've been dragging my ass out of bed between 6 and 7 a.m. for my job now for the last three years and I'm still not getting used to it. My body clock just isn't in the same time-zone. Actually, even if I *change* time-zones to my advantage, in a day or two it wears off and mornings are hell again.

I like your reasoning for us nightfolk.
