If you’re like most, you probably think attraction is a matter of the heart but science plays a bigger role than you think.

Your brain runs a series of complex calculations in a fleeting moment.

And all of your senses are involved.

Your eyes detect characteristics of youth and good health.  A thick, lustrous head of hair, for example, will always get a guy’s attention. 


Because it’s associated with reproductive fitness – a nod to evolutionary psychology, which drives many of our actions when it comes to attraction.

Your nose picks up on natural chemical signals (pheromones), which communicate all kinds of physical and genetic signals to the recipient, albeit unconsciously.

Your ears come into play too.  Men tend to prefer women with high-pitched voices, correlated with smaller body size.    Women prefer lower-pitch voices which suggests a larger body size.

Even taste is a factor!  Studies have shown that both men and women lose attraction for someone after a bad first kiss.  That’s right, the taste of your mouth could either seal the deal or repel her.

After all the messages are sent from your senses to your brain, only then can attraction be established.

Your body is then flooded with norepinephrine, a stress hormone, which activates your fight or flight system.

Your heart beats faster, your pupils dilate and your body releases glucose for more energy – it’s telling you something important is happening. 

The norepinephrine creates tunnel vision, blocks out other distractions, enhances memory and distorts your sense of time.  This is why you feel like time passes quickly on a great date. 

While most of us have adopted a romantic notion of attraction, it is, in fact, influenced more by science than we think.
