@futurebird Ooooh, that explains your perspective. You must be one of those weird people with a circadian rhythm that's exactly 24:00 hours long so it aligns to the natural day-night cycle over a long period of time.
As someone with a sleep cycle with a natural period that varies between 24:30 and 28:00, the disruption you describe is "going to work" for me.
My natural state in the absence of external requirements (e.g. extended WFH periods with no need to wake up at a set time to go into the office ) is to wake up a little bit later each day than the day before. This leads to a slow drift so that if I started out in sync, after two weeks or so I might be waking up around the time my wife is going to bed and getting most of my work done overnight - something i don't mind at all because it ensures a distraction free environment. After another week or two we're back in sync and I'm getting up at 5am without an alarm... Then 5:30, then 6...
The real hell is when I have to get up at the same time every day, say because I'm on a project that requires me to be in the office a lot. I get tired later and later each day but am forcibly waking up more and more exhausted. It would be like you waking up at 6am one day then setting an alarm for 5:45 the next, 5:30 the next, etc. Eventually I crash hard (usually on a weekend) and nap all day then wake up the next alarm somewhat well rested and the cycle repeats.
So I don't mind DST shifts at all, it's business as usual. And if I'm in one of those "going in to work a lot" periods it's actually quite nice being done with work for the day and still being able to enjoy outdoor stuff. Perpetual DST would be fine by me too.
