Could also be dehydration but the most likely cause of that is (1). Even so it might be helpful to start the day with a large glass of water with some rehydration salts? Won't stop you from starting the day with a headache but might make it go away faster.

I struggled with a version of this since my early 20s and the thing that helped me fix 90% of it was 5m of box breathing when I woke up. truly life-changing. there's a video of me doing it in the replies and you can see the change in real timehttps://twitter.com/visakanv/status/1221652619254321154 …

Ah, thanks for the reminder. I've thought multiple times that this sounds interesting and I should give it a go but kept forgetting to follow up and figure out WTF box breathing actually was. Now embarrassed at how simple it is.

maybe the name isn't super great I practice it as basically "take deep breaths and hold to the edge of comfort/discomfort", I don't really count

Interesting. The edge of discomfort is about thirty seconds for me (sixty when I'm in practice, peak of 120 when I'm *really* in practice), which seems a lot longer than is being recommended.

might be using a different discomfort threshold, I mean like when it stops feeling effortless

yes, yes

Hmm, yeah, though you don't achieve long breath holds with effort. It's more like relaxing into it. You can't "do" breath holding, you really do have to stop doing the thing that prevents you from holding your breath.
