Why switching to daylight savings time in the winter is a bad idea

> Think of the last time you had a bad night sleep. You feel bad the next day, but the next night if you sleep well, you'll feel fully recovered from that bad night. But when we spring forward, we often feel bad for weeks. Why does losing that hour have such a profound effect? It is because we are shifted into a state of permanent jet lag with the time change. Your circadian clock follows dawn. The dawn on March 13th in Calgary is at 6:53am, but on DST the next day it is at 7:51am.
(I emphasized the relevant sentence)
I certainly don't feel bad for weeks after the start of DST, I literally don't know what he's talking about. And, if anything, if I feel sleep deprived it's usually because I go to sleep later because I much enjoy having an extra hour of daylight in the evening.
As an example, the paper in https://pubmed.ncbi.nlm.nih.gov/29461606/ discusses and references studies done about this topic.
You should consider that there are people other than yourself and you know, try to be somewhat empathetic or at least non-solipsistic in your thinking. Just because you don’t suffer from a sleep disorder has no bearing in the fact that millions of other people do.
I am sure many people feel bad after the time change, but they may also just feel bad anyway.
This stuff is pretty common knowledge and I’m sort amazed people would be like, “wait, some people aren’t getting a good nights sleep every night? I had no idea!”
That's neither here, nor there. The parent didn't ask how many people have sleep problems, but how many people have sleep problems because of the DST, and even more so, problems that last "2 to 3 weeks" as the article claims.
People have sleep problems for all kinds of reasons (apnea, stress, weight issues, checking Wikipedia at 3am and so on).
Let's try to make the most of the sunlight - personally I'd like lighter evenings, but then I appreciate others may prefer to have more sunlight in the morning.
