How do you know you are in love?

Many of you might answer because I can “feel it in my heart. I have sweaty hands and I can’t get his face out of my mind.”

Don’t worry the experts understand you perfectly. You are in love and when you are in love, the feeling does something to your brain. Some parts of brain will light up and blood will surge creating a more uneasy feeling that is hard to control.

The  neurotransmitters and some the activation of powerful hormones that are responsible for the feeling called love will change something about you.

The love is in your brain...

Love is first activated by the sex hormones testosterone and estrogen in both men and women.

Then.... the:


It said that this chemical is responsible for the feelings of intense pleasure just like the feeling when you take cocaine.

Adrenaline and norepinephrine: 
Make your heart race, palms sweat and mouth becomes dry.

Opioid system: Is responsible for liking: 
When a man is attracted to a woman part of the brain is activated just like when we have a dose of the morphine. According to a study, men who were given doses of morphine rated the picture of women more attractive than men that received no dose.. The researchers think the poiod system can be manipulated to perceive attractiveness.

The feelings called “love” overlooks bad stuff.
The chemical called serotonin in the brain drop when you are in love. Then this makes your love focused only with the good attitudes and not the bad things about your lover. You can’t stop thinking about him as well.


This hormone is powerful in creating the feeling of security. The oxytoxin is called “love hormone”. This hormone is released after a man and woman make love, hug and when a mother nurses her infant.

Oxytoxin helps build trust between people and also has calming effect on people.

Vasopressin aka (anti-diuretic hormone) works with your kidneys to control thirst. This hormone is powerful and just like oxytoxin can be released after making love. It also has a crucial role in forming long-term relationships in people and animals.
The monogamous vs. promiscuous voles:
Thomas Insel, director of the National Institute of Mental Health (NIMH), and colleagues reported that the different mating behaviours of voles can be linked to the hormones oxytocin and vasopressin. 
Prairie voles 
and montane voles are closely related rodents but have a difference in mating behaviour. The prairie voles are monogamous. They form lifelong pair bonds after mating and most won't find another partner when their partner dies. 

Montane voles
are different because they are promiscuous (they have many sexual partners in life). 
The researchers said that Prairie voles have a higher density of both oxytoxin and vasopressin hormones in the moles brains. Both hormones are released when prairie voles mate causing the bonds to form. In the experiment, the oxytoxin and vasopressin hormone’s release was blocked. Surprise, surprise, the prairie voles which was monogamous become promiscuous. The bonds with mates decline and they do not care about other voles running after their partner. And when montane voles were genetically modified the increase of oxytoxin and vasopressin in their brains made them monogamous.

Love affects our brain, behaviour and can make us love till death do us part.
