The earliest that sunrise happens in the continental US is around 5AM during DST, so the earliest it would go is 4AM. That is in the extreme north of the country (excluding Alaska, which I'd say is not worth including in the conversation given its unique circumstances), on the eastern edges of time zones. So I don't know what you're talking about. If you read the article linked above, it specifically points out that there are measurable, concrete negative health effects from DST but not from standard time. So no, the sun rising early doesn't really stress you out the same way getting up before sunrise does. Not at all.

Leaving work in the dark probably causes stress as well. Not to mention that the constant DST switch in of itself causes health stress: https://healthblog.uofmhealth.org/heart-health/why-daylight-saving-time-could-increase-your-heart-attack-risk https://healthblog.uofmhealth.org/heart-health/why-daylight-...

I live farther north and not in the US, but since your decisions on this inevitably impact my own country's I still care about what you do, even if I don't get a say in it. At any rate, yes, the sun rising at 4am would also stress me out. In fact, given that I'm in a position to tell you what it's like in a place where that happens for part of the year, I can inform you from personal experience that it is indeed disruptive to circadian rhythm to have the sun rise even "moderately" early. I'm sure people in Alaska think you're a great person for telling them they don't matter, though.

  Don't need to go to Alaska. Sunrise (with DST) is 5AM with EDT in downeast Maine at the summer solstice and as early or earlier in pretty much every major Canadian city.

Don't neglect twilight. Here in Seattle, sunrise is as early as 5:10am or so in the middle of June. However, with civil twilight included, you're looking at a pretty bright sky from 4:30am to 10pm. We're not even that far north here, but waking up out of a light sleep at 4am can certainly be bothersome.
