> Not that part about how there are more driving accidents on the day we reset our clocks for DST?
This is kind-of a meme talking point these days, but the few studies on this haven’t shown that the cause is lack of sleep, they only show some correlations with the time change (i.e., there could be other factors such as putting commutes in the twilight hours.) There aren’t that many crashes supposedly attributed to DST either (e.g. it’s claimed to be like 30 fatal crashes out of more than 35,000 annually), and the supposed temporary increase in crashes is dwarfed by crash rates in the summer anyway. If you care about car crashes at all, DST is a teensy blip. The big problems are 1:speeding and 2:drunk driving. Making even a modest change to reduce speeding would do many many times more good than eliminating DST.
One massive problem with the cadre of people claiming DST change is so harmful is that the majority of people experience social jet lag on a weekly basis. The one hour time change twice a year is dwarfed by the number of people staying up several hours late Friday and Saturday night all year long. (Full disclosure, I’m skeptical of many of the claims made about DST, and I’ve done deep dives into many references only to find very weak to non-existant evidence being used to support extremely strongly worded claims. The voodoo claims about circadian misalignment that permeate DST “research” are bogus.)
It’d be interesting to self-measure your sleep & next-day performance, that might be a lot more informative than someone else’s summary. It’d be interesting to discuss how to design some self-measure tests. What kinds of performance are you thinking about? Do you want to know the risks of activities like driving, or are you thinking about job/school performance?
