What about all the other studies claiming that poor sleep causes depression? Not sure what to trust these days. Gut tells me poor sleep won't make you ahem "your brain feel slap-happy, loopy and almost giddy" (very scientific).

From the article

>Chronic sleep loss is well studied, and it’s uniformly detrimental effects are widely documented,” Kozorovitskiy said. “But brief sleep loss — like the equivalent of a student pulling an all-nighter before an exam — is less understood.

I guess it also depends on what your past has been.

After going through a "sleep-deprived burnout cycle", I found that any all-nighter will pull me back into the emotions I got at that time, even if I feel originally great physically & mentally.

So, YMMV!

What about them?

This is about one sleepless night every several days/week for an already depressed person.

Not about non-depressed people continuously sleeping poorly (which is where poor sleep would cause depression).

I guess just one sleepless night is not the same as chronic poor sleep patterns.

Also, it's interesting because sleepless nights are kind of a sign in bipolar disorder patients that an (hypo)-manic episode is about to occur or is actually occurring.
