Have you been obsessing about some hot movie star or that cute guy from office/school/college? Do you blush incessantly every time their name is announced? Do you act funny when they are around? Or do you start blabbering to get yourself noticed in front them? If the answer to all these questions is yes, then you, my friend, are the victim of a mental illness, or in layman terms, you have a crush on someone

And the feeling is a bit similar to what we experienced in our teenage years or during PMSing. Our moods choose to swing across various dimensions and you never know what awaits you next.

But why do we have a crush on someone?

Thanks to countless “anti-science” movies, We have always maintained the notion that developing a crush or falling in love has something to do with the heart. Sorry to state the obvious, but it’s all science.

There is more science involved in it rather than just your feelings. In fact, brain chemistry of a crush is similar to that of Obsessive Compulsive Disorder (OCD).

So what exactly is the science behind crushing on someone?

It is our limbic brain, the part of the brain that controls emotions along with other instincts and memories. The limbic brain is responsible for getting addicted to cakes, drugs, or that cute guy from office.

Having a crush causes physical symptoms like flushed cheeks, faster heart rate, and trembling. Well, that explains butterflies in the stomach when our crush is around.

When we have a crush on somebody, chemicals are being released into our brain like dopamine, oxytocin, and cortisol. Dopamine is the same chemical that is released when we consume drugs or have intercourse, a molecule behind all our sinful behaviors and secret cravings.

Our body releases chemical signals called pheromones attracting those whose pheromones are genetically similar to us. We find people with similar interests more appealing because it releases endorphins when we are around the people we enjoy.

We are attracted to people with an immune system different from ours so that our babies can fight off diseases. Also, we are attracted to our opposites so that their traits complement our own for survival. Evolution is awesome, isn’t it?

Psychologists say that if the crush lasts longer than 4 months, it is considered to be love. I don’t know how true it is. But, I think it varies from people to people.

There is no better feeling than your crush being reciprocated. But when the feeling doesn’t go away, it is called limerence. It is a state of infatuated love characterised by uncontrollable thoughts, shortness of breath, and extreme nervousness. You might want to check up with your psychologist.

So all this while when you were thinking it was your heart, it was actually all in your brain.
