It hurts. Like, physically hurts. If you’ve ever felt that weird, hollow ache in your chest after a breakup, you aren't imagining things. Science actually backs you up on this. It’s called Takotsubo cardiomyopathy—literally "broken heart syndrome"—where emotional distress causes the heart’s left ventricle to stun and change shape. It mimics a heart attack. So, when people tell you to just "get over it," they’re basically telling someone with a broken leg to run a marathon. It’s dismissive and, frankly, biologically inaccurate.
The remedy for a broken heart isn't a single pill or a magic phrase. It’s a messy, non-linear reconstruction of your neurobiology.
When you’re in love, your brain is essentially high on a cocktail of dopamine and oxytocin. It’s an addiction. When that person leaves, you go through a literal withdrawal. Researchers at Stony Brook University used fMRI scans to look at the brains of the heartbroken and found that the areas activated are the same ones that light up in cocaine addicts craving a fix. You aren't just sad; you’re detoxing. This is why you find yourself checking their Instagram at 2 a.m. even though you know it’ll make you feel like garbage. You’re looking for a "hit" of that connection.

Stop Waiting for Closure
Honestly, closure is a myth we tell ourselves to feel like we have control. You keep thinking if you could just have one more conversation, or if they could just explain why they did what they did, the pain would stop. It won't. Usually, the "why" doesn't actually help. If they say they didn't love you anymore, it hurts. If they say they’re confused, it gives you false hope, which is worse.
Real closure comes from you. It’s an internal decision to stop the negotiation.
Guy Winch, a psychologist who gave a pretty famous TED talk on this, argues that we have to fight our instincts. Your brain will try to remind you of all the good times. It’ll play a highlight reel of that one sunset on the beach or the way they laughed at your jokes. You have to balance the ledger. You need to remember the times they were emotionally unavailable, the way they made you feel small, or the fundamental incompatibilities you ignored. Write a list of their flaws. Keep it on your phone. Read it every time you feel the urge to text them. It sounds cynical, but it’s a necessary counter-measure to the "halo effect" that heartbreak creates.
The Neurological Reset
One of the most effective parts of the remedy for a broken heart is radical environment change. Because your brain creates neural pathways associated with your ex—like the way you always went to that one coffee shop together—being in those spaces triggers a grief response.
You need to "prune" those pathways.

- Rearrange your furniture. Seriously. It changes the visual landscape of your life.
- Try "Novelty Therapy." Take a different route to work. Start a hobby that has zero association with your past relationship. This forces the brain to create new neural connections, which physically distracts it from the old ones.
- The 90-Second Rule. Dr. Jill Bolte Taylor, a Harvard neuroanatomist, explains that the chemical surge of an emotion lasts about 90 seconds. If you can sit through the peak of a "grief wave" without acting on it (like calling them), the chemicals flush out of your system. It’s the thoughts we attach to the feeling that keep the loop going for hours.
Why "Social Snacking" Fails
We’re social animals. When we lose a primary attachment figure, our nervous system goes into "threat mode." We feel unsafe. A lot of people try to fix this with "social snacking"—scrolling through TikTok or having superficial chats with strangers. It doesn't work. What you actually need is "core regulation." This means spending time with people who make you feel seen and safe. It’s about co-regulation. When you sit with a close friend, your heart rate and cortisol levels actually begin to sync with theirs.
But don't overdo the "venting." There’s a fine line between processing and rumination. If you spend three hours every night analyzing your ex’s last text with your best friend, you’re just deepening the groove of that memory. You’re keeping the wound fresh. Talk about it, yes, but set a timer. Give yourself twenty minutes to wallow, then move the conversation to literally anything else.
Physicality Over Philosophy
You can't think your way out of a broken heart because the problem isn't just in your head—it’s in your endocrine system. Your cortisol (stress hormone) is likely through the roof. This leads to the "breakup flu," digestive issues, and insomnia.
Exercise is often touted as a cure-all, and while it's annoying to hear, the science is solid. Intense physical activity releases endorphins which act as natural painkillers. But even more than that, it provides a sense of agency. When your heart is broken, you feel like a victim of someone else’s choices. Moving your body reminds you that you are still the captain of your physical form.

Also, sleep. Heartbreak causes a specific kind of insomnia where you wake up at 4 a.m. with racing thoughts. This is your body's "fight or flight" system kicking in because it perceives the loss of the pack (your partner) as a survival threat. Taking magnesium or practicing box breathing (inhale for 4, hold for 4, exhale for 4, hold for 4) can help signal to your nervous system that you aren't actually being hunted by a predator.
The Trap of the Rebound
Is a rebound part of the remedy for a broken heart? Maybe. But usually not in the way people think. Seeking validation from someone new can provide a temporary dopamine spike, but it often leads to a "crash" when you realize the new person isn't your ex. The "rebound" only works if it's used as a way to remember that you are still a person who is capable of being desired, rather than a way to replace the intimacy you lost.
Most people use rebounds to avoid the "void." The void is that quiet space where you have to be alone with yourself. It’s terrifying. But the void is actually where the healing happens. You have to learn how to be a singular unit again rather than half of a pair.
Actionable Steps for Moving Forward
If you’re struggling right now, stop looking for a "fix" and start looking for "integration." The goal isn't to forget the person—that’s impossible—but to integrate the experience into your life story so it no longer hurts to look at.
- Audit your digital space. Mute, don't just unfollow. Seeing their face in a "memory" pop-up can set your progress back by weeks. You need a digital "clean room."
- Focus on "Low-Stakes Wins." Your self-esteem is likely trashed. Start small. Clean a drawer. Finish a book. Complete a 5k. These small completions rebuild the "competence" centers of your brain.
- Check your narrative. Are you telling yourself "I am unlovable" or "This specific relationship didn't work"? One is a death sentence; the other is a data point.
- Engage the senses. Use weighted blankets to simulate the physical pressure of a partner, which can lower cortisol. Use scents like lavender or citrus to ground yourself when a panic attack hits.
- Volunteer. It sounds cliché, but "helper’s high" is a real biological phenomenon. Shifting your focus from your own internal pain to someone else's needs can break the rumination cycle.
Healing isn't a straight line. You’ll have days where you feel invincible and days where you’re crying in the grocery store because you saw their favorite brand of cereal. That’s not failure; that’s just how the brain re-calibrates. Treat yourself with the same radical empathy you’d give a friend. You’re essentially recovering from a major injury. Give it the same respect and patience.
