More substantively, I agree with other commenters who have said all this shows is that there are people who have lower depression who wake up one hour earlier. Definitely does seem like clickbait.
And yet here you are.
I think we are mixing cause and effect here. It might also not be correlated. I mean, it may well be cultural, to rise earlier when you are feeling fine, but those two facts, early rising and emotional health, might not have a cause and effect relationship at all.
