I see. Many cultures use the same words to describe the pain and the feelings that go with losing a relationship.
Yes it feels almost hard to breathe. It is physical pain.
Hey. My heart hurts from a broken relationship... That's too bad. A broken heart is a metaphor, but it can refer to physical pain or stress. That's interesting. What else do you know about broken hearts? It's a concept that's thought to be universal. Many cultures use the same words to describe it. Ah, OK. Is there anything physically happening when we feel a broken heart? Yes, there's a neurological process that may overstimulate the vagus nerve, which causes pain, nausea, or chest tightness. Yeah, that sounds like a broken heart. To go into more detail, the neurological process is believed to include anterior cingulate cortex, which is in the brain. Oh, that's complicated. I just know it hurts.
The concept is believed to be universal, with many cultures using the same words to describe both physical pain and the feelings associated with relationship loss.
