The Ella Era · The Physiological Cost of Going Viral - Dr Justin Coulson explains · 22 Jun 2026 podcast
And your talking brain, like the bit where you, right now you're listening to me, Ella, and you're hearing my words and your brain's computing the words, it's processing the words and you're getting ready to say stuff.
That's all happening just here in front of or above your left ear.
So you know how when somebody says something and it's just so sharp, so cutting and you go, oh, I need to come back and you can't think of one.
And then 20 minutes later, you think of the great comeback.
That's because once again, there's no blood and oxygen happening up here in this left hand above the ear part of the brain because back there.
So essentially to answer your question, your brain goes into overload.
It goes into fight or flight.
It goes into emotional overdrive.
and therefore you stop thinking well.
There's this thing that I talk to parents about all the time, and that is that high emotions equals low intelligence.
The more emotional you become, the dumber you become, basically.
And I know that's not a very nice thing to say, but it's kind of real.
Someone cuts you off on the road, you get really emotional, you start saying dumb stuff.
You have a fight with your partner because they've left their tea bag in the sink in the kitchen for the 400,000th time, even though you've told them not to, and your brain goes, whoop, like this, and your intelligence goes out the window.
So that's kind of what's going on with trolling.
Yeah.
Well, the very, very far downstream effects, if you're like that all the time, is that you end up having a heart attack.
You end up having a massive, like, but we're talking like way down the track because when you get into this fight or flight mode, when you get into this high anxiety mode,
You increase all the cortisol, which is a stress hormone buzzing around your body.
You increase the adrenaline pumping around your body, makes your heart pump faster.
