moment of bliss that changes the rest of their life. And we’re not the only ones, even

animals have fully monogamous relationships. Look they cuddle and everything. But what

exactly is love? Let’s finally answer the question that’s perplexed scientists for

generations. Oh and if you stay long enough I might even tell you how you can make someone

love you.

Love is free, it can’t be owned, bought or sold. Is has no mass or weight and cannot

be touched. Yet it is the single most powerful emotion humans can experience. It makes us

do some really stupid stuff sometimes. But it’s far more than an emotion, it can physically

affect our bodies in some rather incredible ways.

For example, some extraordinary research revealed that when two lovers gaze into each others

eyes, their heart rates synchronise and beat at the exact same time. This graph shows the

heart rates of two individuals in love, whilst their eyes were locked in a loving exchange.

The red line shows one heart beat, the blue line the other, notice how their heart rates

are so closely matched, so much so, that the blue line can barely be seen beneath the red

line.

Love is also a powerful pain killer. In fact, cuddling can cure a headache, during a loving

embrace the chemical Oxytocin is released in our brains, ovaries and testicles. Research

has found that a dose of Oxytocin can significantly decrease headaches and other pains. Studies

have also shown that simply looking at a photo of a loved one can reduce pain by up to 40%.

So then, what is love?

Well, this really depends on how you look at it, some people say love is down to fate,

our path is already decided, out of our control. That sure sounds poetic, but the processes

associated with love can actually be extrapolated and explained to a large extent by science.

But I should warn you, this won’t be romantic, unless statistics turn you on.

Psychologists have shown that it takes anywhere between 90 seconds and 4 minutes to decide

if you fancy someone. Surprisingly being attracted to someone has very little to do with what

they say, research shows that 55% is through body language, 38% is the tone and speed of

their voice and only 7% is down to what they say.

In order to properly explain love we must first break it down into its 3 stages, lust,

attraction and attachment. Each stage is driven by its own set of unique hormones and chemicals.

A person must go through all 3 stages before they can truly be in love with someone, which

kind of puts a spanner in the whole “love at first sight” thing.

The first stage, Lust is probably the most biologically simple, lust is driven by the

sex hormones testosterone and oestrogen. In fact research shows that women actually have

different tastes in men whilst using contraception. Women taking the pill prefer men with more

feminine faces, whereas women not using contraception prefer more masculine men.

But what’s even more interesting is that the features that trigger lust in a person

differs between genders. Research shows that men are attracted to women that have a symmetrical

face, full lips, full breasts, and wide hips compared to their waist size, or to put in

more simply an hourglass figure. Because statistically curvy women are also the most fertile. In

fact there’s actually some maths behind this, in European countries the most desirable

waist-to-hip ratio in women is 0.7, and in South America and Africa it’s 0.9.

On the other hand, women prefer men with broad shoulders and a narrow waist. But most intriguingly,

one of the most desirable qualities in a man is a healthy immune system. Research shows

that women are subconsciously attracted to men with healthy faces, because this signals

a strong immune system.

Stage 2 is Attraction, this is the stage when you’re deeply in love and you can’t think

of anything but your new partner. Scientists think there are three main neurotransmitters

involved with this stage, adrenaline, dopamine and serotonin.

Firstly, adrenaline along with the stress hormone cortisol are released in your body

during the first few weeks of your new relationship. These two chemicals are responsible for making

you sweat, increasing your heart rate and giving you a dry mouth when you’re around

your new love interest.

Secondly, your levels of dopamine increase, this gives you an intense rush of pleasure

when you bump into your new love and it’s what makes you desire them even more. Increased

dopamine levels also increase your energy levels, and decrease your need for sleep and

food. It actually has a very similar effect on the brain as taking cocaine.

And finally, whilst you’re in the attraction stage, your levels of the serotonin neurotransmitter

drop dramatically. This causes you to become obsessed with your new love interest, it’s

the reason they keep popping into your thoughts throughout the day. Interestingly the low

serotonin levels experienced by new lovers are remarkably similar to the low serotonin

levels found in patients with Obsessive-Compulsive Disorder.

Lastly, the final and most important stage of love is attachment. During this stage the

powerful bond is formed that keeps some couples together for life and makes them want to have

children. Research shows there are two major hormones responsible for this feeling of attachment.

Oxytocin and vasopressin.

Both the oxytocin and vasopressin hormones are released by men and women, when they kiss,

cuddle and have sex. Scientists believe that the more sex a couple has, the deeper their

bond becomes.

An interesting example of this can be seen with prairie voles. Like humans, they indulge

in far more sex than is necessary for the purpose of reproduction, and they also, like

humans, form stable pair-bonds. As part of an experiment, scientists gave prairie voles

a drug that suppresses the effect of the vasopressin hormone. Something remarkable happened, their

bond with their partner deteriorated immediately and they no longer protected their partner

from potential new suitors.

So in a nutshell, the answer to the question “What is love?”, is “Love is a state

of deep attachment to a fellow human being, caused by a combination of chemicals. Specifically:

Testosterone, Oestrogen, Adrenaline, Dopamine, Serotonin, Oxytocin and Vasopressin”.

Sounds so romantic doesn’t it? I do apologise if I’ve somewhat ruined the magic. But remember,

these are nothing more than scientific explanations for a set of symptoms and behaviours associated

with being in love. In reality, love truly is a seemingly magical and rather beautiful,

force of nature that could never be fully explained by science.

But there’s still the question of “why” does love exist, what purpose does it serve?

Evolutionary scientists believe that love is a product of evolution. The theory goes

like this. Without love acting as the glue, in a relationship, keeping a partner long

enough to reproduce is difficult. If love wasn’t a component in most relationships,

they most likely wouldn’t last longer than a couple of weeks. Which, means a lot fewer

couples would reproduce. It’s love, that keeps relationships together for several years

or more, long enough for them to have children, which, after all is the ultimate goal of evolution.

Scientists believe that over millions of years, humans, and certain other animals, have developed

a specific set of chemical processes, to make us feel like we are emotionally attached to

our potential mating partner. Thus giving us an incentive to want to stay together and

ultimately reproduce. We, however, interpret this, as being in love.

But you may be thinking, if the sole purpose of love is just an incentive to reproduce.

Then why do we love our family, and even our pets? It all has to do with the attachment

hormone we talked about before, Oxytocin. It isn’t just released when we have sex,

it’s also released in somewhat smaller doses when we simply touch another person, or animal.

Every time we touch another person and experience a release of Oxytocin, we become more deeply

attached to them. And who do you think you came in contact with the most as a baby, that’s

right, your family.

Ever heard the phrase “There’s nothing like a mother’s love”. Well there really

isn’t, during the later stages of pregnancy Oxytocin levels in the mother surge to unfathomably

high levels, these levels peak right at the moment of childbirth. This creates a seemingly

unbreakable bond and an unrivalled level of attachment between the mother and child.

But it’s not just humans that release Oxytocin. Scientists have discovered that dogs and cats,

among many other animals, also release Oxytocin when they come into physical contact with

another animal, or human. So good news animal lovers, this means, that your pet really does

love you too. Scientists found that the more you socially interact with your pet, the more

deeply they become attached to you, and hence the more deeply they will fall in love with

you.

So then, like I promised here’s how you can make someone fall in love with you. It’s

really quite simple, find a potential new suitor, it doesn’t even have to be someone

you know. Reveal some intimate details about your life to them, then stare deeply into

their eyes for 4 minutes. There’s a slight chance you may get a slap, but research shows

that more often than not they will feel strangely attracted to you.

New York psychologist, Professor Arthur Arun, demonstrated this when he randomly paired

people together from a group of complete strangers and asked them to reveal intimate details

about their lives to each other for 30 minutes, then stare deeply into each other’s eyes

for 4 minutes. Afterwards nearly all of the couples admitted to feeling deeply attracted

to the stranger, whom they had only spent 34 minutes with. And following the experiment

one of the couples actually got married.

If for some weird reason you don’t feel comfortable imposing your newly learned Jedi

mind tricks on a complete stranger. Fear not, there are some slightly less insane things

you can do to increase the chances of your crush falling in love with you.

Research shows that proximity has a huge effect on love. A study in Ohio showed that 54% of

couples who recently applied for marriage licenses were separated by a distance of 16

blocks or fewer and 37% were less than 5 blocks apart from each other. The science behind

this is repeated exposure. The more you see someone or something the more you like it.

However this is not always the case, repeated exposure to another person amplifies the dominant

emotion in the relationship. So if the dominant emotion is anger or hate, they’re just going

to dislike you even more. But the bottom-line is, if you want someone to fall in love with

you, you should spend as much time as possible in their company. Unless you really, really

annoy them.

Research shows that individuals whom are in a state of emotional distress are significantly

more likely to fall in love. This state of emotional unease is often found following

the death of a loved one, being in an accident, or most commonly, after a painful breakup.

Obstacles that stand in the way of love can actually increase the chance of a relationship

forming. Studies show that attraction is actually increased when external factors get in the

way. A great example of this is when teenagers start a relationship and their parents object,

it only makes the teenagers want to be together even more.

Finally, I’ll leave you with these facts. Women tend to find men twice as attractive

when they notice other women are interested in him. Also, on average, a man will spend

one year of his life staring at women. It’s also common to think that men are less emotionally

affected by relationships than women. But statistically, men are quicker than women

to say “I love you” in relationships and contrary to popular belief, recent studies

have shown that men are more emotionally affected when a relationship ends than women.
