Happy hormones, happy heart: the science of love and mental well-being
Valentine’s Day is the perfect time to celebrate love, kindness, and human connection
But did you know that love isn’t just a warm, fuzzy feeling in your chest? It’s also a complex cocktail of hormones working behind the scenes to brighten your mood, boost your mental and emotional well-being, and leave you feeling on top of the world.
Here in Mzansi, we love to say, “ Local is lekker. Perhaps love could be lekker as well.”
But what can make it so lekker, scientifically speaking? Let’s dive into the fascinating science of love and uncover how those happy hormones - dopamine, oxytocin, serotonin and endorphins - bring joy, health and happiness into our lives.
Love and the brain: a match made in science
While we often associate love with the heart, the brain is actually the mastermind behind it all.
According to neuroscience research, “Love is a neurochemical reaction that activates several regions of the brain. It’s a powerful force that affects our emotions, decisions, and even physical health.”
When you fall in love or feel deeply connected to someone, your brain releases a flood of happy hormones. Each plays a unique role in making you feel good, helping you bond, and improving your mental well-being.
The fab four: your love hormones explained
Here’s a breakdown of the four key hormones that fuel love and happiness:
Dopamine: the pleasure seeker
Dopamine is often called the “feel-good hormone” because it’s responsible for that rush of excitement and euphoria you feel when you’re around someone you love.
Think of that fluttery feeling in your stomach when you receive a sweet text or share a romantic moment it’s dopamine doing its thing.
Fun fact: Dopamine is also released when you indulge in chocolate, which might explain why Valentine’s Day chocolates are such a hit.
Oxytocin: The bonding hormone
Known as the “love hormone” or “cuddle chemical,” oxytocin is released during physical touch, like hugs, kisses, and even holding hands. It helps build trust and strengthens emotional bonds, making it a key player in long-term relationships.
Research also shows that oxytocin reduces stress and promotes a sense of safety and calm. No wonder snuggling feels so good!
Fun fact: Moms release oxytocin during childbirth and breastfeeding, which helps them bond with their babies.
Serotonin: the mood booster
Serotonin is a natural mood stabiliser that helps regulate your emotions, reduce anxiety, and improve your overall sense of well-being.
It’s released when you feel valued, appreciated, or loved whether that’s from a romantic partner, a close friend, or even your fluffy pet.
Fun fact: Spending time outdoors in the sunshine can boost serotonin levels.

Endorphins: the natural painkillers
Endorphins are your body’s way of saying “You’re doing great.” These hormones are released during exercise, laughter, and even when you eat something spicy. They help reduce pain, relieve stress and make you feel genuinely happy.
Fun fact: Couples who laugh together tend to have stronger relationships, thanks to the endorphin release that comes with sharing a good giggle.
Beyond making you feel good at the moment, these love hormones have long-term benefits for your mental health.
According to psychology, “Strong relationships whether romantic, platonic, or familial are linked to lower levels of depression, anxiety and loneliness. Love and connection are essential for our well-being.”
Even small acts of love, like smiling at a stranger or showing kindness to a colleague, can trigger happy hormones and uplift your mood.
So, don’t limit yourself to romantic love this Valentine’s Day - spread the love far and wide!
