Cupid’s chemicals

Abu Jar

Love is the most beautiful gift in this world which brings tons of happiness with joy for our life. When we first fall in love, we can’t stop smiling. It is a divine feeling! Suppose you saw someone and suddenly you are getting flushed cheeks, a racing heart beat, and sweaty palms, then congratulations my friend, you are in love. In other words you have love bug. Hence we can say that love isn’t a just random thing, there are some mysterious chemicals, neurons and hormones those are working together to make us fall head-over-heels for someone.

It can be said that love may be one of the most studied, but least understood, behaviors. Helen Fisher which is a biological anthropologist studied 166 societies and found evidence of romantic love, the kind that leaves one breathless and euphoric—in 147 of them. Another associate professor of psychiatry named Schwartz of McLean Hospital in Belmont said: “there’s good reason to suspect that romantic love is kept alive by something basic to our biological nature.”

Actually, falling in love is getting into a beautiful trap set up by nature. So love is nothing but a natural occurrence which we cannot fight or ignore. According to a science-based study by Arthur Arun, ‘the mind of a normal person takes between 90 seconds to 4 minutes on average  to determine whether it is struck by love or not.’ The study also points out that 55% of the role in love is played by body language; this means a brain detects the activities of body movement and decides. It also tells that 38% of the decision to be in love is contributed by the voice of our desired one and 7% is the reaction in love is due to a lover’s statement or choice of words.

A recent study based on the topic “science behind the love” is conducted at Rutgers University by Helen Fisher. She has proposed that we fall in love in three stages named lust, attraction, and attachment, each involving a different set of chemicals.

Lust, Lust is the first stage of love and it is driven by the sex hormones testosterone and estrogen. Testosterone is not only found in men but has also been shown to play a major role in the sex drive of women. These hormones as Helen Fisher says “get you out looking for anything”.

Attraction, This is the truly love-struck phase. Definitely, when we fall in love we can’t think of anything else! They often lose their appetite and some time may pass a sleepless night. Actually, they prefer to spend hours is day dreaming about their beloved one.

In the second stage of love, a group of neurotransmitters called ‘monoamines’ play a crucial role,

  • Dopamine – cocaine, and nicotine also activate it.
  • Norepinephrine – Also known as adrenaline. It makes us sweating and gets the heart pumping.
  • Serotonin – One of the love’s most important chemicals and one that may actually send us temporarily insane.

Attachment, Attachment is a bond which helps the couple to take their relationship to advanced stages. In other words, the attachment is the bond that keeps a couple together longs enough for them to have and raises the offspring. Many scientists believe that there might be two main hormones working behind the feeling of attachment. One of them is Oxytocin and the other one is known as Vasopressin.

Oxytocin, This is actually released by the hypothalamus gland during child birth and it also helps the breast to express milk. Therefore it is responsible for creating the strong bond between mother and child. It is also released by both males and females during orgasm and it is thought to have increased the bonding a couple when they are intimate.

Vasopressin, A very important chemical which plays a significant role in the long-term commitment stage. It is considered to be a pivotal controller of the kidney and its role in long-term relationships was first discovered when scientists looked at the prairie vole.

At the end, we call all these chemical reactions as love. To us, it feels like love because it makes us feel like flying in the sky. But the most important thing is that all these human emotions are probably nature’s beautiful way of keeping the humans alive and reproducing. When our brain entices us to fall in love, it feels like our body releases an irresistible cocktail of chemicals. We believe we’re choosing a partner, but actually, we may merely be the happy victims of nature’s lovely plan. We can agree that love is one of the most delightful feelings of our lives and may be it would be not wrong if we say that “love is blind” because you never know when your brain will encounter love.
