I’ve suddenly started noticing colours everywhere, fragrant
aromas and soft winds, the purple puff of Pretoria ’s
Jacaranda filled streets, bees are buzzing and the birds are singing... And
many of the songs you hear are mating calls. Yes, spring and summer signal the arrival of that
sexual behaviour in mammals that we call mating season. While it is clearly
seen in hares and deer, I am very sceptical to refer to any specific time of
the year as that being the human “mating season”. We have an Afrikaans saying
that quite appropriately sums this up: Heeltyd speeltyd!
However, there is just something about summer, isn’t there?
There are some things that we observe which I can’t help but wonder whether
these are mating behaviours. How else can we explain the excessive number of
love junkies at the moment?
“You’re being bombarded by pleasant, exciting, novel stimuli,
and novelty stimulates the neurotransmitter dopamine, which in turn triggers
testosterone production,” says Dr. Helen Fischer, a neuroscientist, professor
at Rutgers University and author of five books on
the science of love. Dopamine is the naturally occurring chemical your brain
uses to make you want things. While there are other systems involved in love,
when it comes to new love, dopamine is the main culprit. And with enough of it
swirling around your system, you're prone to fall in love - and fall hard.
Friends, your body has turned into a dopamine factory. Did
you know that brain scans of people flooded with the stuff look a lot like
brain scans of drug addicts? I suppose this makes sense, since being high on
dopamine feels, as many lovers would put it, euphoric.
Enough with the romance. Let's cut to the real science.
