Introverts: Quietly High on Their Own Brain Chemicals
by Hella Cliques July 14, 2025
If you think introverts are just shy weirdos avoiding the party punch bowl, science would like a word — and that word is acetylcholine. That’s right. While extroverts are out chasing dopamine hits from loud music, group selfies, and pretending small talk is a skill, introverts are quietly getting lit on an entirely different neurochemical.
Acetylcholine is the lesser-known, introvert-friendly neurotransmitter that rewards you for introspection, focus, and chilling the hell out. For introverts, sitting alone with a good book, journaling about the meaning of mortality, or having a deep conversation with one trusted human being is basically the equivalent of a rave. Just with more tea and fewer glowsticks.
It’s not that introverts don’t like people — they just don’t need a swarm of them to feel alive. Their brains are literally wired to light up when things are calm, thoughtful, and at least ten feet from any group karaoke machine.
Meanwhile, extroverts need social buzz to get their dopamine drip. That’s fine — you do you. But maybe don’t drag your introvert friend to yet another “networking mixer” and then wonder why they’re hiding behind a ficus.
So the next time someone says introverts are “missing out,” you can smile politely (from a safe distance) and remember: introverts aren’t avoiding the party — they’re enjoying the very real biochemical rewards of being left alone.
