We’ve all said it…there was chemistry. Or maybe, there just wasn’t. It’s the phrase we reach for when logic fails, when attraction feels too complex to name. But what do we actually mean when we talk about chemistry?
The word suggests science - formulas, reactions, an invisible spark that either ignites or doesn’t. Yet in practice, “chemistry” isn’t chemical at all. It’s something felt: a combination of timing, emotion, and the way two people make each other come alive.
The myth of instant connection
Movies have taught us that chemistry happens at first sight. That one glance across a crowded room can change everything. And sometimes, it can but more often, that instant rush is just familiarity disguised as fate.
Psychologists describe it as emotional recognition: we’re drawn to people who feel familiar, who mirror patterns we already know even when those patterns aren’t necessarily healthy. It’s why we can feel “chemistry” with someone who challenges or destabilises us. The body mistakes intensity for intimacy.
Real chemistry, though, is less about adrenaline and more about attunement. It’s not the chaos of the spark, but the ease of understanding. The feeling that someone sees you and not just the version you curate.
The science beneath the feeling
Of course, there’s biology at play too. When we’re attracted to someone, our brains release dopamine, oxytocin, and norepinephrine which are the same chemicals linked to reward and excitement. It’s why early connection can feel addictive. The body lights up and we chase the feeling.
But what we call chemistry is rarely just about biology. If it were, it would fade once hormones settled. Instead, the strongest connections grow beyond that first rush. They become a kind of emotional synchrony where you not only desire someone, but feel safe with them.
That’s the quiet kind of chemistry we don’t see in films: less electric and more enduring.
The cultural obsession with the spark
Our culture glorifies chemistry. We use it to explain love at first sight and to justify heartbreak. If something ends, we say the spark faded. If it never began, we say it wasn’t there. Chemistry becomes both the reason we fall and the excuse we can’t.
But this obsession with “the spark” can make us overlook something deeper. Relationships built only on chemistry often burn out quickly - the same fire that draws us in can consume the connection entirely. Desire without understanding is easy; desire with understanding takes time.
Sometimes the people we feel least “spark” with at first become the ones we end up trusting most. Chemistry isn’t always instant. Sometimes it’s the slow warmth that builds once the noise quiets down.
Chemistry and the stories we tell
When we talk about chemistry, we’re really talking about how it feels to be seen. About wanting to be mirrored, met and recognised. It’s not just about attraction, it’s about energy. The shared rhythm between two people who make sense together, even when nothing about it makes sense.
But that feeling is also shaped by our history. Our attachments, our fears and our self-image all inform who we find magnetic. The chemistry we crave often says as much about us as it does about them.
Maybe that’s why it’s hard to define. Chemistry is part biology, part biography. It’s both body and story.
Beyond the spark
The longer we live, the more we realise chemistry isn’t the goal but it’s the entry point. It’s the initial curiosity that draws two people close enough to discover something real.
Lasting intimacy comes later. It’s built in the quiet moments and the familiar touch, the unspoken understanding, the safety to be honest. Chemistry might start a story, but it’s empathy, trust and choice that sustain it.
So when we say we had chemistry, what we really mean is something in me recognised something in you. A spark of self mirrored back, a shared pulse for a fleeting moment.
And maybe that’s enough. Because chemistry isn’t what love depends on but rather it’s what reminds us we’re still capable of feeling it.
