Governments Worldwide Consider Ditching Daylight Saving Time

This was done to save electricity. More direct sun, less light and heating.

Historically in France the saving was equivalent to the whole consumption of the city of Paris over the day (maybe 10-20% of the whole country).

It seems people don't care about energy anymore ¯\_(ツ)_/¯

This is so not a thing to me. I never ever realise we chabged until someone tells me and im like "oh ok".

People who complain about it are a bit "Snowflake Inc." to me.. sorry.

The article is mostly suitably modest about mechanisms, focusing on the epidemiology of the observed effects, and it's more or less obvious to me that the transitions are disruptive to everyone, and especially so to sensitive individuals.

But there's also a bit in the answer to the fourth question (about long-term vs short-term impacts) that mentions effects of "chronic circadian misalignment". I've seen this a few times in various contexts, and it has always seemed to me that if this is what's driving some problems, one ought to be able to compare populations from different ends of an especially wide time zone, e.g. northwestern Indiana and Maine in the US, which are more than 15 degrees of longitude apart, but both in the US Eastern time zone. Surely one or the other of these groups always has at least half an hour of circadian misalignment?

Edit to add: On re-reading, I caught the bit at the end of the "abolition" question where there is a reference to what I wanted, apparently there are studies showing that people in the eastern side of the Central time zone get more sleep than people on the western side. There's even a link (to the Elsevier paywall, alas, but still...) https://www.sciencedirect.com/science/article/abs/pii/S01676...

Edit 2: 15 degrees of longitude, not latitude.

I like that twice a year we acknowledge the construction of time

Interesting that in the last 10 years some governments that got rid of the DST were accused of dismissing global warming by their political rivals
