ELI5: Why does the feeling of 'love' quite literally feel so heavy in your chest?
gpt
The feeling of love is something that is pleasing to the mind psychologically (obviously). It is one of the most potent stimulator for the release of certain chemicals stored in the body into the bloodstream. The body releases a cocktail of chemicals into your blood every time the mind is filled with love that act directly on your heart to make it beat faster, among other things. The heaviness you feel is literally your heart squeezing more blood and beating faster. Not the most comprehensive explanation, but hope this helps.
