> Surely one or the other of these groups always has at least half an hour of circadian misalignment?
What is circadian misalignment? Nothing I see on Wikipedia backs up the idea that circadian rhythms are aligned to solar noon (which is what the interviewee in the article claimed). https://en.wikipedia.org/wiki/Circadian_rhythm
The very idea of chronic circadian misalignment due to DST seems a bit suspect since we know circadian rhythms are driven in part by changes in light, and they adapt reasonably quickly over time to changes in environment (“entrainment”). Sunrise and sunset are the main changes in light, while solar noon is one of the moments when light is changing the least. We also know computer screens and indoor lighting are affecting circadian rhythms, so isn’t it likely that games, Netflix and internet use are orders of magnitude more concerning than a one hour shift twice a year. DST is a smaller change in my sleep habits than my weekly swing!
