Question: Is
There Really a Chemistry of Love?
Answer: I
don't think there are any magic love potions that you can use to make someone
fall in love, but chemistry does play an important role in how a relationship
progresses. First, there's attraction. Nonverbal communication plays a big part
in initial attraction and some of this communication may involve pheromones, a
form of chemical communication. Did you know that raw lust is characterized by
high levels of testosterone? The sweaty palms and pounding
heart of infatuation are caused by higher than normal levels of
norepinepherine. Meanwhile, the 'high' of being in love is due to a rush of
phenylethylamine and dopamine. All is not lost once the honeymoon is over.
Lasting love confers chemical benefits in the form of stabilized production of
serotonin and oxytocin. Can infidelity be blamed on chemistry? Perhaps in part.
Researchers have found that suppression of vasopressin can cause males (voles,
anyway) to abandon their love nest and seek new mates. Hey, you gotta have
chemistry!
