ELI5:Why when going through periods of great emotional distress does ones heart sometimes physically hurt?
gpt
It isn't your heart, really. Well, to be more accurate, it is PROBABLY not your heart. Stress can make your heart beat faster due to the release of adrenaline (fight or flight response) which increases your heart's demand for oxygen in the cardiac muscles. But, it also causes the superficial muscles in your chest to contract along with many other areas of your body. THIS is probably what the pain is rather than your actual heart.
