One of my friend is a chemistry gal, I have lots of discussion with her, those discussion tends me to relate small things with chemistry. Today when i read one article about love and passion in our new generation, how self generated chemical fills love in our lives. I found one interesting thing that love is all about chemistry, the more chemicals your body generates the more you fall in love. In simple English, it is a "natural drug" that can give us a total kick. When we fall in love, this PEA chemical gets released into our bodies and turns us into total love junkies. Our palms begin to sweat, our hearts begin to palpitate, and our minds become filled with loving thoughts. We become attached to our beloved of desire and want to spend 24/7 with them.

Love, like all things bound to the universe, is non existent without some amount of chemistry attached to it. Cupid’s arrows would never have been effective if they had not been first dipped in one unromantically named chemical- phenylethylamine(PEA). We have two more chemicals dopamine and norepinephrine, chemical cousins of amphetamines. Dopamine makes us feel good and norepinephrine stimulates the production of adrenaline, makes your heart race! These three chemicals combine to give us LOVE or "chemistry." It is why lovers feel euphoric and energized, and float on air. It is also why lovers can make love for hours and talk all night for weeks on end.  

Cuddling

The chemical oxytocin  "bonding chemical"  has been termed the cuddling chemical. It plays an important role in romantic love that signals orgasm and prompts cuddling between lovers before, during, and after lovemaking.

Oxytocin production is derived from both emotional and physical cues. A lover's voice, his/her certain look can trigger the release of oxytocin.

Attachment

When infatuation subsides, a new group of chemicals takes over. This new type of chemical reward is created by endorphins.

These morphine-like opiates calm and reassure with intimacy, dependability, warmth, and shared experiences. Not as exciting or as stressful as PEA, but steadier and more addictive.

The longer two people have been married, the more likely it is that they'll stay married. In part, they become addicted to the endorphins and marital serenity. It is the absence of endorphins that make long-time partners yearn for each other when apart. Absent endorphins also play a part in grief from the death of a spouse.

Overdose reactions

Heady emotions, racing pulses and heavy breathing results, and all these are (unfortunately) clinically explained as an overdose of this chemical.

Parkinson’s disease could be one.  

PEA sources

A very interesting thing is that chocolate is known to have very high level of this chemical…perhaps that’s the reason why it is considered a perfect gift for valentine. Or for your sweetheart.

The real adventure comes when you meet your beloved one. If there is a right connection between you two, streams of PEA will begin to flood out. It will blast your brain and blind you from logic as you experience the sensations of being in love.

So final conclusion is chemicals play a role in all three stages of love : Crush, attraction and commitment.

Stage 1: Crush

driven by the hormones estrogen and testosterone.

Stage 2: Attraction
driven by the Dopamine, Norepinephrine and Serotonin

Stage 3: Commitment
driven by the Vasopressin and Oxycontin.
