Why do breakups hurt so much?

Why does rejection hurt physically?

Because the brain doesn't have a separate circuit for emotional pain. Being left out of a game activates the anterior cingulate cortex, an area linked to physical pain (Eisenberger and colleagues, 2003). Looking at a photo of an ex after an unwanted breakup also activates areas that register bodily pain (Kross and colleagues, 2011).

That's why you might feel pressure in your chest, a lump in your throat, or a heaviness in your whole body. You're not being dramatic: the signal is real.

What happens in your brain when you get dumped?

Several parts of the brain work at once, pulling in different directions. The reward system keeps asking for the person, the pain areas give the loss physical weight, and the prefrontal cortex, the part that puts the brakes on impulses, tries to restore order.

The prefrontal cortex is the part that knows you shouldn't text them. It loses strength when you're tired or alone, which is why nights are so hard. Texting them anyway isn't a character flaw. If that urge is your problem right now, read how not to text your ex.

Is a breakup like withdrawal?

Partly. When they looked at a photo of their ex, people who had recently been rejected and were still in love activated regions linked to intense cocaine craving (Fisher and colleagues, 2010). That doesn't mean a breakup is an addiction: the study had 15 participants.

Here's the useful part: if the urge runs on reinforcement, every bit of contact recharges it. That's what no contact is for. It's not pride or a way to punish the other person: it's about no longer feeding the circuit.

Why do I feel physically sick after a breakup?

Because a breakup works like a stress that lasts for weeks. Your sleep, appetite, and routines get thrown off, and your body feels it. Even so, most people get through a breakup well (Sbarra, 2015).

Broken heart syndrome, or takotsubo syndrome, is a rare heart problem that can show up after intense stress. If you have chest pain or shortness of breath, go to the emergency room now. If you have thoughts of hurting yourself, talk to a professional or call your local emergency number.

How solid is the evidence?

It's real, but more limited than the headlines suggest. The main studies used MRI scans with groups of 9 to 40 people. They show that certain brain areas activate during rejection, not how long it will last for you.
