Why does heartbreak cause physical pain in your chest?

After my breakup I have been feeling actual physical pain in my chest. Not a heart attack kind of pain but a dull aching feeling that won't go away. I also feel nauseous and can't eat. Is heartbreak actually physical or is it all in my head?

It's absolutely physical. Studies using brain scans show that emotional pain activates the same regions as physical pain. Your body releases stress hormones that can cause muscle tension, chest tightness, and even immune suppression.

The vagus nerve connects your brain and your gut which is why heartbreak causes nausea and loss of appetite. Your body is genuinely in distress, not just your mind.
