The Look of Love <3
When it comes to love (or lust, as the case may be), men and
women know what they like when they see it. Ask people to describe their ideal
romantic partners, and they might draw a blank or merely offer a vague outline,
but that doesn't matter so much, since they'll immediately know when they
encounter him or her. According to Rutgers University anthropologist Helen
Fisher, the human body is such a finely tuned attraction-seeking machine, it
takes only one second to intuitively decide whether someone's physically hot or
not [source: Fisher]. Upon closer inspection, we might change our minds, or we
just might have found what we've been looking for all along.
To help ensure that the good ones don't get away, our bodies
produce a host of physical signs of attraction that grab our attention and
direct it toward the dreamboat in question. When those physiological mechanisms
kick in, even a brief glimpse of a crush can leave us short of breath and
dazed. And unpleasant as some of these reactions might be, we can at least take
heart that at some point, the following five lovesick symptoms happen to all of
us.
Top 5 Physical Signs of Attraction:
Be Still My Beating
Heart
Why do literature and art always associate romance and the
heart? Because our hearts are set aflutter, pulses literally racing, at the
sight of someone attractive [source: Fisher]. In fact, the heart-attraction
relationship is so potent, studies have found that increasing someone's heart
rate and then putting him or her near a pretty stranger can artificially ignite
a flame of affection [source: Foster et al].
Per usual, the brain is ultimately responsible for this
physiological response, not Cupid and his archery acumen. During early-stage
romantic love -- scientific terminology for the honeymoon phase -- the brain
releases norepinephrine whenever we're around a love interest to shake us into
action [source: Obringer]. That adrenaline-like neurotransmitter spurs our
motivational decision-making, possibly prodding us to chat up Mr. or Ms. Right.
Meanwhile, our adrenaline-addled hearts are likely pumping faster than usual in
order to get us through the taxing ordeal
Sweating the Small
Stuff
If you're introduced to someone who immediately makes your
heart go gaga, it might be best to avoid a handshake. Sweating palms is a
classic physiological response to attraction. The same cocktail of chemicals
that prods our pulses also stokes our sweat glands. Collectively known as
monoamines, dopamine, norepinephrine and serotonin combine to produce feelings
of excitement, with a side of breathlessness and moist hands [source:
McLoughlin]. Norepinephrine in particular is the culprit for goading our sweat
glands into activation, and since our palms are riddled with up to 3,000
miniscule sweat glands per square inch, they can quickly become a telltale
signal of sexual interest.
Men also might be stricken with sweaty palms more often than
women. Rutgers University anthropologist Helen Fisher suggests that since men
are more visually stimulated than women, their brains dole out bigger doses of
monoamines
Be Mine, Baritone
Repeated studies have confirmed that heterosexual women
prefer deeper voices whispering sweet nothings in their ears. In addition to
associating lower-pitched male voices with masculinity, women associate those
bass notes with authority, larger body size and physical attractiveness
[source: O'Luanaigh]. Fortunately for tenors out there, a recent Australian
study at least debunked the notion that a deeper voice intimated superior sperm
quality [source: Parry].
Perhaps since deeper-pitched voices have attracted such a
sexy reputation, people may lower their registers when speaking to their
special someones. In a 2010 study, male and female study participants were
asked to record messages to be played for fictional recipients. Researchers
showed individual participants photos of fictional message recipients; the more
attractive participants rated the fictional recipients, the more likely they were
to deepen their voices [source: PhysOrg]. But a conflicting study found that
the more tantalizing the male face, the higher -- not lower -- women raised
their vocal pitch [source: Fraccaro et al]. Either way, it seems we attempt to
fine tune our voices to sound like sweet music to our beloveds' ears.
Jeepers Peepers
Dusty Springfield wasn't talking nonsense when she sang
about "The Look of Love." The chart-topping blonde with the golden
voice belted out scientifically plausible lyrics about come-hither eyes, as
studies have shown that our pupils play an active role in signaling attraction.
When we spot a comely face, our brains release dopamine, which triggers pupil
dilation [source: Murphy]. Thanks to the surge of dopamine in our brains that
excites the nerve endings in our eyes, the pupil muscles contract and dilate
our peepers [source: Spiers and Calne].
But pupil preferences aren't uniform across the board, and
bigger isn't always better. Whereas heterosexual men find women with larger
dilated pupils more feminine and beautiful, most straight women opt for medium
male dilations that signal sexual interest, but not to a potentially violent
extreme [source: Tombs and Silverman]. However, women who tend to engage in
short-term sexual relationships with "bad boys" were googly-eyed for
the larger pupils as well [source: Tombs and Silverman].
Copycats
Nineteenth-century British writer and aphorism documentarian
Charles Caleb Colton ushered the phrase "Imitation is the sincerest form
of flattery" into common usage in 1820 [source: Martin]. Come to find out,
Colton's adage applies quite well to interpersonal attraction. When people
interact in dating scenarios, and things are going well, body language
mirroring often happens subconsciously. For instance, someone will lean in
close to the dinner table, and other person follows in suit.
Better yet, without knowing it, these subtle gestures also
serve to stoke each other's romantic egos. A 2009 study on mimicry in a speed
dating environment revealed that men gave more favorable ratings to women who
slightly mirrored their verbal and nonverbal patterns [source: Gueguen].
Scratching their faces after the men scratched their faces, for instance,
ultimately increased the women's sexual attractiveness after the 5-minute interaction
[source: Jarrett]. If that body language exchange sparks a long-lasting
relationship, men's and women's bodies tend to play copycat as they age
together as well. According to a 2006 study, the longer couples stick together,
well after the jittery symptoms of attraction have calmed, the more they
physically begin to look alike
