Sleep Schedule Shift

Over the last several months, I've been trying to get myself to wake up at a more reasonable hour. There were days where I had ended up staying up until three or four in the morning and then I'd be in bed until noon or later. It seemed fun initially, but over time, I got sick of it. I got tired of missing out on most of the day. I hate that I'm on a completely different schedule to the rest of the world. So I started using my alarm clock again (specifically an app on my phone). For a while, I would wake up with it, or I would just ignore it, but then something changed.

I like being able to get up earlier in the morning. I can get my steps in earlier in the day. I can actually do breakfasty stuff without feeling like I need to justify "you can eat breakfast anytime!" Since I'm getting up earlier on a more regular basis, I get to see more daylight and that's a good thing. I'm not getting quite the same sense of lack of accomplishment, because I actually do get more done in the day.

What's interesting though is that I have recently been waking up earlier than my alarm. Even if I end up going to bed later than I should, I still wake up before the alarm, sometimes even a full hour before. Sure, sometimes it's just that thing where you wake up, realize you've got time, then go right back to sleep. This past week, I've been awake before the alarm goes off, and I just get up. I'm up and about before the music from my alarm starts.

I don't know what changed, but I'm totally okay with it.

There are studies that show an abnormal sleep schedule can lead to depression and other detrimental states of mind. I don't know if that's what's been troubling me as of late, but I can't rule out that it has had an impact. I'm hoping I can maintain this more productive sleep schedule and also develop a routine, something that lets me accomplish more of what I want to accomplish for me, not just household tasks. If I can find a routine for my writing, that would be fantastic.

Has anyone else had their sleep schedule just spontaneously change like this? I feel like it's a shift that happened without me really doing anything that different.
