For a few months my wife had a baking job that required her getting up at 4. I’d get up with her and start to work after breakfast. I’d have the days work before 9:00 standup. More time for sport and cooking. Think it was a healthier lifestyle in total. Social life was impossible though, we couldn’t manage to stay awake long enough to meet up with friends. And impossible to maintain once she switched to another shift.

Being very much not a morning person, I get a taste of that too when I have jet lag traveling west. Even after the feeling of jetlag subsides after a few days, I tend still tend to wake up earlier for two more weeks or so.

It's a different world and definitely has advantages. However, like you, I'm not sure it's worth the tradeoff of being horribly tired long before my usual bedtime.

In total, I think I still prefer getting up late and sleeping late.

I've found that effective noise-cancelling headphones(e.g. Sony WH1000XM4) help somewhat.

In my experience they help a lot and that's why people (colleagues, family members, the mailman...) are so busy finding new ways to circumvent them.
