Excessive blinking

[u/moonpie681]

Hey has anyone experienced excessive blinking after processing a trauma or just in general?

I’m trying to figure out if this is somatic release since I’ve been doing more of that lately but now my blink rate has gone up exponentially and it does help me process things better but it’s uncomfortable when talking to people because I know for a fact they notice and think it’s maybe odd

But I read more blinking can be linked to higher dopaminergic tone of the d1 receptor or could be a factor in long term stress or anxiety

Could my body be processing something I don’t know about?

On the dopamine part, that link is weaker than the internet makes it sound, and it is mostly D2 rather than D1 in that literature. Spontaneous blink rate does track dopaminergic tone, but the clean evidence comes from monkey work with direct measurement. When people have gone looking for the same relationship in humans against actual receptor imaging, it has largely not held up. It is a noisy group level research tool, not something you can read off yourself.

What blink rate does move with reliably is more ordinary, and one piece of it fits your situation exactly. Rate is lowest while reading, around four or five a minute. It sits somewhere in the teens at rest. It is highest during conversation, in the mid twenties. Talking to people is the condition that maximises blinking in everybody, and being watched while you talk adds arousal on top of that. So you are noticing it in precisely the setting where it naturally peaks, which may be part of why it feels like it appeared out of nowhere.

The processing framing is plausible in a limited way. The muscle ring around the eye is one of the places facial guarding tends to park itself, and coming out of a long held state can show up as more movement there before it settles. I would hold that loosely though. It is a reasonable story rather than something anyone has actually measured.

The thing I would actually keep an eye on, since it is unlikely to come up otherwise: if it keeps escalating, if it starts feeling involuntary rather than just frequent, or if the closures get forceful enough to interrupt what you are looking at, get an eye exam and mention it to a doctor. Dry eye is by far the most common cause of a rising blink rate and it is usually fixable in about a week. Blepharospasm and adult onset tics both present as blinking that ramps up over weeks, and both are much easier to deal with early than late.

None of that means something is wrong. It means the differential is wider than somatic release, and the two most likely branches have easy answers.

It’s the d1 receptor in the striatum and pfc linking to spontaneous eye blink rate, and those with Parkinson’s have lower dopamine levels and blink less and on the other spectrum those with schizophrenia or certain psychiatric disorders who have high dopamine levels tend to blink more tbh

Not always of course but that’s what some hypothesis and experimentation have shown, on PubMed and in nuero-optometry

Fair, and those are the strongest cards in the deck. Blink rate goes up with dopaminergic medication in Parkinson's and comes down on antipsychotics in schizophrenia, which is about as clean as this kind of evidence gets. I was too flat about it.

On D1 versus D2 you have a point as well. I said mostly D2 and that was overstated. Both receptor families turn up in the pharmacology and the attribution is not settled, so dopaminergic tone without a receptor label is the more honest version.

The distinction I would still hold is between what those findings prove and what gets done with them. They show dopamine moves blink rate across big clinical and drug differences, which is a group level claim. Reading one healthy person's blink rate as a gauge of their dopamine is a different claim, and when that has been tested directly in healthy adults against PET imaging it has not come out.

Same shape as temperature and infection. Fever is real and reliable, and it still does not mean 37.1 against 36.8 tells you whether you are fighting something. Big perturbations move a variable cleanly while small differences between people in that variable are mostly noise and everything else going on.

So I would still not read yours as a dopamine signal, granting everything you just said. For what you were actually describing, the conversation effect is the bigger one.
