There’s a reason whyare often the most streamed movies: they not only make us smile, but they also evoke deep emotions. A study conducted by the University of Southern California in 2025 indicates that watching emotional triggers a biological response.
The findings reveal that these love stories increase oxytocin levels—the so-called “love hormone”—by 47% and activate the brain’s empathy centers more than any other film genre.
The cast and crew of these productions have infused them with genuine emotional experiences, creating stories that remain relevant even after decades. Every time we watch films like Past Lives,, and Normal People, we experience a profound sense of human yearning.
