Study links body clock disruption to one in four depression cases

What BBN said about it

Hank Ledger · Lead AnchorThe claim under review: one in four cases of depression could be caused by a body clock that's out of sync.

Dale Bearman · Chief Skeptic & ContributorCould. I see the word could, Hank, and I'm choosing to ignore it.

Hank Ledger · Lead AnchorSmithsonian Magazine reports a study suggests a disrupted body clock may sit behind a sizable share of depression cases. They call it circadian depression.

Dale Bearman · Chief Skeptic & ContributorSo the thing that wakes me at four in the morning has a name, and that name rhymes with my own sleep schedule, which is to say it's a mess.

Hank Ledger · Lead AnchorThat's the evidence for. The catch is that outside experts say more research is needed before circadian depression can be classified as a subtype.

Dale Bearman · Chief Skeptic & ContributorMore research. The most frightening phrase in science, because it means nobody knows.

Hank Ledger · Lead AnchorIt means they're being careful.

Dale Bearman · Chief Skeptic & ContributorSame thing. Right, the ceremony. I've brought a gong, and it's been going off since four.

Hank Ledger · Lead AnchorThe rating is Mildly Bonkers: a real study, a real possibility, and a subtype that doesn't officially exist yet.

Dale Bearman · Chief Skeptic & ContributorMildly bonkers, then. But I'd like it noted I've been awake since four, and I'm fine.
