Love On The Brain: What Science Says Loving Someone Does To You Mentally

I dig science. A big part of the reason why is because I really enjoy researching the “whys” of things. While my father always liked that about me, my mother oftentimes had something slick to say about it (that’s another message for another time, chile). To me, it’s whatever. For better or for worse, I’m simply not someone who accepts that the sky is blue “just because” — put it on my daddy’s DNA, I guess; with no apologies in place, I almost always want to know why something is the way that it is.
And since I spend so much of my time working with couples and writing on relationships, I’m sure no one is shocked that I’ve done my due diligence when it comes to figuring out what is really going on in the minds of humans whenever they are hyped about being in love. While on the surface level, it might seem like I’m being cynical, I’m actually not. It’s more about…well, again, I’ve been working with couples and writing about relationships for so long at this point that I think it’s important for folks to know the difference between an “emotional surge” and a truly wise love decision — and being aware of the role that the brain plays when we think that we’re in love with someone? That can help to bring some perspective and clarity into all of this.
So, whether you’re in something new and you’re currently on cloud nine, you’ve been in something for a while now and you’re wondering if you’ve “lost that loving feeling” or if you’re borderline on the verge of self-sabotage or, you’re like me, and you simply like to know random information just because — I’ve got 10 things that might be of interest to you as far as what science says love can literally do to you on the mental tip.
It’s fascinating stuff, indeed.
1. Dopamine Gets Activated
It’s pretty interesting thatdopamine is a type of neurotransmitter that plays a significant role in things like how you are able to experience pleasure or create memories because both of those are quite relevant when you’re in love with someone. Well, according to science, when you feel like you truly love an individual, dopamine gets activated on a whole ‘nother level to the point where you not only feel euphoric but,it’s at the level of what alcohol or a cocaine high can produce (have mercy!) I’m not exaggerating, either.
In fact, Medical News Today once published an article entitled, “Falling In Love Hits The Brain Like Cocaine Does.” Hmm…makes you wonder if some people run up outta there marriages, not because there’s really anything “wrong”; it’s just that they have crashed from their “cocaine high” and no one prepared them for how to handle it (get into premarital counseling, engaged folks; it makes all the difference in the world!). Also,as far as dopamine goes, when men are “falling” for a woman, it’s dopamine and vasopressin that increase, while, for women, it’s dopamine and oxytocin. During sex, vasopressin drops in men, while oxytocin increases when a woman climaxes. The more you know.2. Euphoria Increases
Let’s go a little bit deeper into the whole euphoria thing. At the end of the day, euphoria is about intensity. I mean, a part of the reason whythe series Euphoria has been so popular (and jarring) is that it showshow drug abuse can put people into a euphoric state — at first in a pleasurable way and eventually on a devastating level. When it comes to love, some experts say that three stages transpire when you feel like you’re in a love-related euphoric state:arousal, attraction, and attachment. And you know what? If you aren’t intentional about doing what Ben Franklin once said (“If passion drives you, let reason hold the reins.”), you could find yourself being on a roller coaster of emotions without having a relationship that consists of much stability. Yeah, euphoria increasing can be problematic as hell if you don’t get all of what comes with that.
3. Oxytocin Surges
When it comes to the articles that I’ve written on love, sex, and relationships on this platform, I don’t know if there’sany hormone that I’ve shouted out more than oxytocin. That’s because there are countless amounts of intel supporting the fact thatit bonds people through things like hand-holding, cuddling, kissing, and definitely sex. That’s whysome experts say that oxytocin can cause people to become “single-minded” about a person, it cancultivate feelings of trust, and it can literallycreate physiological changes that cause you to seek out your love interest.
This is a part of the reason why, when people declare that they are “in love” after say, a one-night stand, my mind immediately thinks, “Eh. Sounds more like an oxytocin surge.” You don’t know them well enough to love them; you can “love” how they make you feel, though. It’s essential to know the difference.
4. Fear Decreases
Now, this is an interesting one. Something else that science says happens when people are in love is the neural pathway that is associated with things like fear and judgment. It actually deactivates itself (chile…CHILE). Yep, some studies reveal that the part of your brain that encourages you to make “critical assessments” of individuals. When you feel like you love them, that shuts down. As a direct result, in walks the rose-colored glasses, and out goes the red flags. And that’s why, when I recently read that a particular actor didn’t heed some warnings from her friends regarding her new relationship, I literally shook my damn head.
When you’re all in love, especially in the beginning stages, having folks around who don’t feel the same ways about the person as you do can actually help you out in the long run, so long as they are good friends with a solid track record, they are going to notice some things that your neural pathway is keeping you from paying close attention to. Yeah, y’all be careful out there.
5. Your Prefrontal Cortex Slows Down
Speaking of desensitized senses, something else that transpires when you’re caught up in someone isyour prefrontal cortex becomes sluggish. Why is this problematic? Well, that’s where the logical part of your brain is housed. This means that when you love someone, you may not be the best at making sound and practical decisions. Although I don’t agree with an article that said this means that love is illogical (love is sound, sane, and stable; it’s folks who jack relationships up…not love), I do think all of this is a reminder that you must rely on more than just how someone makes you feel when you’re trying to decide who to build a life with. Moving on.
6. Your Hypothalamus Revs Up Your Sex Hormones
I don’t know about y’all, but I don’t know too many people who aren’t attracted to the object of their love and affection. And so, when you do fall in love, something else that happens isthe part of your brain known as the hypothalamus stimulates your ovaries while it also stimulates your man’s testicles — and that is what makes you feel an overwhelming feeling of desire (i.e., lust) for your partner.
7. Your Brain’s “Reward Circuit” Lights All the Way Up
Speaking of longing for your partner, three parts of your brain — the amygdala, the hippocampus, and the prefrontal cortex — are known as its “reward circuit,” and whenever you even speak about your bae, this is the part of your brain that lights up like a Christmas tree. Something that’s really interesting about this particular point is, that while this is happening, your serotonin levels typically drop.
Why does this matter? Well, serotonin helps to keep your anxiety levels in balance, and it also helps you to regulate your appetite(s). This would automatically cause me to believe that people who struggle with love addiction probably have a low level of serotonin operating in their system.
Oh, speaking of serotonin, although you may never think to get your hormone levels checked strictly to learn more about how you’re acting/reacting in your romantic relationship,I also found it interesting that people who have more dopamine in their system tend to take more risks when it comes to love while those who have more serotonin are usually far more cautious. Meaning, that how you are in your relationship(s) may not be just about your personality; your hormone levels tend to have a say as well.
8. Your Anterior Cingulate Cortex May Make You Obsessive
Your anterior cingulate cortex is the part of your brain that’s associated with things likemotivation and action. Anyway, since overactivity in this part of the brain is oftentimes linked to things like obsessive-compulsive disorder,some researchers believe that the reason why some people seem to think obsessively about their partner, almost to the point of obsession, if they don’t stay on top of it, is because of how their brain reacts to their attachment to their partner.For the record, this is also the part of your brain that literally lights up whenever you see your partner, too.
9. Vagus Nerves “Sync Up”
Your vagus nerves are a part of your nervous system that starts at your brain and runs through your digestive tract. This makes them an integral part of things like your immunity, your speech, your moods, and your heart rate. As far as your brain goes, some studies reveal that after a couple has been together for a longer period of time, it’s not uncommon for their vagus nerves to “sync up” in the sense of having similar facial expressions and hand gestures being and even their hearts starting to beat at the same pace.As a direct result, the syncing makes it easier for both individuals to make sacrifices for one another in order to remain together. Share that with your grandparents the next time you see them. #wink
10. If You’ve Been Together for a While, Your Angular Gyrus Becomes Stronger
Speaking of longevity, another perk that comes with couples who choose to go the distance is the part of their brain known astheir angular gyrus becomes more active. What’s actually sweet about this is that not only is this what makes it easier for you to learn complex languages, but you can also start to anticipate your partner’s actions with it too. As a direct result, science says that many couples can finish each other’s sentences — and it’s all because their angular gyrus has gotten stronger as a result of them staying committed.

After reading all of this, how could anyone possibly look at being in love casually? There are far too many intricate parts at work — yes, literally. Yeah, when Rihanna sang about having “love on the brain,” she said more than a mouthful…whether she realized it or not.
And if you declare that you are in love, make sure to factor in what your brain is going through. Then choose wisely. Even your brain and mental health depend on it. Also…literally.

It's kinda wild that, in 2025, my byline will have appeared on this platform for (what?!) seven years. And yeah, when I'm not waxing poetic on here about sex, relationships and then...more sex and relationships, I am working as a certified marriage life coach, helping to birth babies (as a doula) or penning for other places (oftentimes under pen names).
As some of you know, something that I've been "threatening" to do for a few years now is write another book. Welp, October 2024 was the month that I "gave birth" to my third one: 'Inside of Me 2.0: My Story. With a 20-Year Lens'. It's fitting considering I hit a milestone during the same year.
Beyond that, Pumas and lip gloss are still my faves along with sweatshirts and tees that have a pro-Black message on them. I've also started really getting into big ass unique handbags and I'm always gonna have a signature scent that ain't nobody's business but my own.
As far as where to find me, I continue to be MIA on the social media front and I honestly don't know if that will ever change. Still, if you need to hit me up about something *that has nothing to do with pitching on the site (I'm gonna start ignoring those emails because...boundaries)*, hit me up at missnosipho@gmail.com. I'll do what I can. ;)
Eva Marcille On Starring In 'Jason’s Lyric Live' & Being An Audacious Black Woman
Eva Marcille has taken her talents to the stage. The model-turned-actress is starring in her first play, Jason’s Lyric Live alongside Allen Payne, K. Michelle, Treach, and others.
The play, produced by Je’Caryous Johnson, is an adaptation of the film, which starred Allen Payne as Jason and Jada Pinkett Smith as Lyric. Allen reprised his role as Jason for the play and Eva plays Lyric.
While speaking to xoNecole, Eva shares that she’s a lot like the beloved 1994 character in many ways. “Lyric is so me. She's the odd flower. A flower nonetheless, but definitely not a peony,” she tells us.
“She's not the average flower you see presented, and so she reminds me of myself. I'm a sunflower, beautiful, but different. And what I loved about her character then, and even more so now, is that she was very sure of herself.
"Sure of what she wanted in life and okay to sacrifice her moments right now, to get what she knew she deserved later. And that is me. I'm not an instant gratification kind of a person. I am a long game. I'm not a sprinter, I'm a marathon.
America first fell in love with Eva when she graced our screens on cycle 3 of America’s Next Top Model in 2004, which she emerged as the winner. Since then, she's ventured into different avenues, from acting on various TV series like House of Payne to starring on Real Housewives of Atlanta.
Je-Caryous Johnson Entertainment
Eva praises her castmates and the play’s producer, Je’Caryous for her positive experience. “You know what? Je’Caryous fuels my audacity car daily, ‘cause I consider myself an extremely audacious woman, and I believe in what I know, even if no one else knows it, because God gave it to me. So I know what I know. That is who Je’Caryous is.”
But the mom of three isn’t the only one in the family who enjoys acting. Eva reveals her daughter Marley has also caught the acting bug.
“It is the most adorable thing you can ever see. She’s got a part in her school play. She's in her chorus, and she loves it,” she says. “I don't know if she loves it, because it's like, mommy does it, so maybe I should do it, but there is something about her.”
Overall, Eva hopes that her contribution to the role and the play as a whole serves as motivation for others to reach for the stars.
“I want them to walk out with hope. I want them to re-vision their dreams. Whatever they were. Whatever they are. To re-see them and then have that thing inside of them say, ‘You know what? I'm going to do that. Whatever dream you put on the back burner, go pick it up.
"Whatever dream you've accomplished, make a new dream, but continue to reach for the stars. Continue to reach for what is beyond what people say we can do, especially as [a] Black collective but especially as Black women. When it comes to us and who we are and what we accept and what we're worth, it's not about having seen it before. It's about knowing that I deserve it.”
