I'm surprised at the number of commenters who think permanent DST is favourable to night owls and bad for morning people. I think it's night owls and delayed-cycle teenagers attending school who will suffer most under permanent DST. In the Winter, permanent DST means everyone has to get up an hour earlier for work or school's clock time, relative to the sun which regulates their body rhythm. Someone pointed out virtu…
I really don't get what you're saying. Move the clock 4 hours forward and you favor some people; Move it backwards and you favor others. You literally cannot make everyone live in their "perfect sleep cycle." If you feel sleepy "at 2am" this changes nothing for you. In Norway in December people wake up "in the middle of the night" because sunrise is at 10am: Humans can adjust easily to this stuff, it's just that we l…
I argued that commenters who say permanent DST specifically favours night owls are incorrect about who it favours, because they (most of them) haven't considered the effect of the sun on sleep quality and daytime cycles.
My view is that most solar-affected night owls will have slightly worse sleep and daytime energy and metabolism, because clock-time social requirements will not change (that's the point of changing the clocks after all). Sunshine after will work will make people happier after work, which is reflected in economic activity, but I think the insiduous effects on health are being ignored. There is some scientific research to back up this point of view.
There are early risers here who don't like permanent DST saying "we're not all night owls like you", believing the change is designed to favour night owls.
There are night owls here who say permanent DST will be great for them because there will be less sun in the mornings to ruin their sleep. That implies they have a choice about when to wake, or they are thinking of Summer. They are in the minority even for night owls, because the change applies only to Winter, when most people are already forced by social requirements to get up when it's dark. There is no light streaming in that early in Winter. Permanent DST will only mean that it's dark for longer after they get up.
