Science of the Physical Pain Associated with Heartbreak
You lose a part of yourself when connections are lost, and its not far-fetched to say that you feel completely empty inside. There’s an ache, a deep ache that erupts from the inside of our bodies longing for the past. The pain is real and there’s no other way to describe how bad it really hurts than to name it heartbreak.
When a person feels secluded or feels loss, changes in the brain’s blood flow occur. The anterior cingulate cortex (responsible for regulating physical pain distress) becomes more active during these times, causing the physical pain associated with heartbreak. (via)
