Do you remember being a kid and counting down the days until summer vacation felt like it would last forever? Like, actually forever. Two months was an eternity.
And now? Two months flies by in what feels like two weeks. Maybe that's just me getting older, but I genuinely think about this all the time. Like, where did this year GO?
Well, apparently I'm not just being dramatic. There's actual science behind this, and it's kind of blowing my mind.
The Dopamine Discovery
A new study from researchers at UCLA just published in Nature Communications has found something fascinating about how our brains process time. And it all comes down to dopamine—that feel-good chemical your brain releases when something exciting happens.
Here's the deal: when we experience something new, our brain releases dopamine, which helps create more detailed memories of that moment. And because our brains remember these moments more vividly, they feel like they lasted longer.
To test this, researchers had people listen to different tones while getting their brains scanned (MRI, specifically). When participants heard a tone signaling something new was about to happen, a key dopamine-producing area called the ventral tegmental area lit up. And here's the wild part—when this brain region was super active, people reported that more time had passed, even during the exact same interval.
They also noticed that people blinked more during these "new event" moments—and more blinking meant people remembered those periods as lasting longer. (I know, blinking as a time predictor is kind of weird, but stick with me here.)
Why This Explains So Much
The researcher behind this study, Dr. David Clewett, puts it this way: our memories aren't like a video recording. They're more like a film editor going through footage, deciding what to keep and what to toss.
Your brain is constantly deciding which moments are "important enough" to remember in detail. Novel experiences get that special treatment. Routine stuff? Your brain basically shrugs and moves on.
So here's the thing: when you're a kid, almost EVERYTHING is new. New experiences, new places, new people. Your brain is creating detailed memories constantly, which makes those periods feel extended.
But as an adult? We're stuck in our routines. Same commute, same coffee shop, same Netflix shows. Our brains aren't bothering to create detailed memories of things we've done a thousand times. So time feels like it's zipping by.
This Is Actually Good News
Look, I found this research genuinely exciting because it means we can actually do something about this. We can't stop aging, obviously, but we CAN inject more novelty into our lives.
Dr. Clewett says dopamine gets released when we take up creative hobbies, visit new places, or do anything that feels fresh and exciting. So maybe the answer to making life feel longer isn't some complicated hack—it's just... doing new stuff.
I'm definitely going to try this. Maybe it's finally that pottery class. Maybe it's exploring that neighborhood I've been meaning to check out. Maybe it's just cooking something I've never made before.
I figure if I can trick my brain into making more detailed memories by experiencing more new things, maybe I can stretch out my perception of time a little. At the very least, it'll be more interesting than watching the same three shows on repeat.
Has anyone else noticed time speeding up as they've gotten older? Or have you found ways to slow it down? I'd love to hear what's working for you.
