Look, if you, like so many people, are full energy, bright-eyed and bushy-tailed at that hour, then yes, you should use that time for doing all the things you talk about (and it’s a lot). But research has also shown that not everyone’s circadian rhythm conforms to this cycle. It’s called having a “late adjusted chronotype.” Yet we don’t live in a world that allows us to rise on our own timetable — we’re forced to wake ourselves up and go to work or school at the times set by Industrial Era management. We are not bright-eyed and bushy-tailed; we’re sleep-deprived and exhausted. Yet rather than advocate for flexible work hours, the world around us just keeps moralizing about how we just need to get up earlier! And do lots of things in the morning! And then everything will be great! Well, sure, if I’m allowed to sleep until I’m fully rested, I would have more energy and be willing to journal and eat breakfast and do some yoga before starting work. But I don’t have that luxury. If you’re going to use science to back up your thesis, you should look beyond your own narrow experience.
