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 that dopamine 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 why the series Euphoria has been so popular (and jarring) is that it shows how 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’s any hormone that I’ve shouted out more than oxytocin. That’s because there are countless amounts of intel supporting the fact that it bonds people through things like hand-holding, cuddling, kissing, and definitely sex. That’s why some experts say that oxytocin can cause people to become “single-minded” about a person, it can cultivate feelings of trust, and it can literally create 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 is your 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 is the 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 like motivation 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 as their 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.

Exclusive: Viral It Girl Kayla Nicole Is Reclaiming The Mic—And The Narrative
It’s nice to have a podcast when you’re constantly trending online. One week after setting timelines ablaze on Halloween, Kayla Nicole released an episode of her Dear Media pop culture podcast, The Pre-Game, where she took listeners behind the scenes of her viral costume.
The 34-year-old had been torn between dressing up as Beyoncé or Toni Braxton, she says in the episode. She couldn’t decide which version of Bey she’d be, though. Two days before the holiday, she locked in her choice, filming a short recreation of Braxton’s “He Wasn’t Man Enough for Me” music video that has since garnered nearly 6.5M views on TikTok.
Kayla Nicole says she wore a dress that was once worn by Braxton herself for the Halloween costume. “It’s not a secret Toni is more on the petite side. I’m obsessed with all 5’2” of her,” she tells xoNecole via email. “But I’m 5’10'' and not missing any meals, honey, so to my surprise, when I got the dress and it actually fit, I knew it was destiny.”
The episode was the perfect way for the multihyphenate to take control of her own narrative. By addressing the viral moment on her own platform, she was able to stir the conversation and keep the focus on her adoration for Braxton, an artist she says she grew up listening to and who still makes her most-played playlist every year. Elsewhere, she likely would’ve received questions about whether or not the costume was a subliminal aimed at her ex-boyfriend and his pop star fiancée. “I think that people will try to project their own narratives, right?” she said, hinting at this in the episode. “But, for me personally – I think it’s very important to say this in this moment – I’m not in the business of tearing other women down. I’m in the business of celebrating them.”
Kayla Nicole is among xoNecole’s It Girl 100 Class of 2025, powered by SheaMoisture, recognized in the Viral Voices category for her work in media and the trends she sets on our timelines, all while prioritizing her own mental and physical health. As she puts it: “Yes, I’m curating conversations on my podcast The Pre-Game, and cultivating community with my wellness brand Tribe Therepē.”
Despite being the frequent topic of conversation online, Kayla Nicole says she’s learning to take advantage of her growing social media platform without becoming consumed by it. “I refuse to let the internet consume me. It’s supposed to be a resource and tool for connection, so if it becomes anything beyond that I will log out,” she says.
On The Pre-Game, which launched earlier this year, she has positioned herself as listeners “homegirl.” “There’s definitely a delicate dance between being genuine and oversharing, and I’ve had to learn that the hard way. Now I share from a place of reflection, not reaction,” she says. “If it can help someone feel seen or less alone, I’ll talk about it within reason. But I’ve certainly learned to protect parts of my life that I cherish most. I share what serves connection but doesn’t cost me peace.

Throughout each episode, she sips a cocktail and addresses trending topics (even when they involve herself). It’s a platform the Pepperdine University alumnus has been preparing to have since she graduated with a degree in broadcast journalism, with a concentration in political science.
“I just knew I was going to end up on a local news network at the head anchor table, breaking high speed chases, and tossing it to the weather girl,” she says. Instead, she ended up working as an assistant at TMZ before covering sports as a freelance reporter. (She’s said she didn’t work for ESPN, despite previous reports saying otherwise.) The Pre-Game combines her love for pop culture and sports in a way that once felt inaccessible to her in traditional media.
She’s not just a podcaster, though. When she’s not behind the mic, taking acting classes or making her New York Fashion Week debut, Kayla Nicole is also busy elevating her wellness brand Tribe Therepē, where she shares her workouts and the workout equipment that helps her look chic while staying fit. She says the brand will add apparel to its line up in early 2026.
“Tribe Therepē has evolved into exactly what I have always envisioned. A community of women who care about being fit not just for the aesthetic, but for their mental and emotional well-being too. It’s grounded. It’s feminine. It’s strong,” she says. “And honestly, it's a reflection of where I am in my life right now. I feel so damn good - mentally, emotionally, and physically. And I am grateful to be in a space where I can pour that love and light back into the community that continues to pour into me.”

Jon B. Talks New Album, 18-Year Marriage & Being A Girl Dad
Since 1995, Jon B. has been entertaining us with his soulful voice, belting out R&B classics like “They Don’t Know” and “Someone to Love.” Despite his immense success, Jon decided to prioritize his family and take a step back from the music scene. He got married, and together, he and his wife had daughters. While he didn’t release any new music during this period, Jon remained dedicated to his fans by touring and maintaining his connection with them.
"I'm raising two daughters," he tells xoNecole exclusively. "One is 11 now, and one is 18, and both need their dad. Besides being a father, a rock star on the weekends, and a husband of 18 years, the real thing that kept me the busiest over the last 10 years was the road, keeping the bread on the table, and staying with my fans. Nevertheless, connecting with the fans and keeping that relationship alive. Regardless of whether I was on the radio every five minutes or whatnot. I just wanted to keep that relationship alive, and the best way to do that is just go and perform."
A decade later, Jon B. dropped a new album, WAITING on YOU. The album title alone is a nod to fans who have been waiting on him to release new music. The "Are You Still Down" singer collaborated with Rick Ross, Alex Isley, Tank, and Donell Jones on the album, giving fans a little bit of everything.
"Compiling this album was a labor of love because it was me sort of picking the gems. I wrote so many songs over the last 30 years. I wanted to go back and dust some old gems off and see if I can rework these records," he says. "Some of them are kind of reworks from back in the day, from back in the late '90s. I just kind of love the beat. One of the songs on my album is a vintage cut. I'll call it a vintage cut because I did it in '98. It's a song called "Pick Me Up."
"There's a little bit of the old and a little bit of the new, but WAITING on YOU, I felt was an appropriate name for the album, being that it was 10 years and it's really about my relationship that I have with my fans. Not only is it the relationship I have with my wife and my children, it's the extended relationship I have with with you guys, the listeners."
"There's a little bit of the old and a little bit of the new, but WAITING on YOU, I felt was an appropriate name for the album, being that it was 10 years and it's really about my relationship that I have with my fans."
His wife and kids are his biggest supporters and he shared that they sometimes give their opinion on his music. When it comes to his relationship with his wife, he says communication and patience are the keys to lasting. "I don't mean to sound like Dr. Phil up in here, but 18 years, going on 19, and it's like, I'm not counting, but I guess we're doing something right because we're very happy people," he says.
"I'm making music that reflects what I feel in my heart, which is pretty cool to share with the world now as a grown ass man instead of a guy who was growing up and had an old soul and I was figuring stuff out. I'm grateful for those records, but I really feel like these records are like a guy celebrating everything that I've been blessed to experience so far."
