All you need is LOVE

Science Savvy

In this episode of Science Savvy, we're diving into the science of love—beyond just romance. From the neuroscience that drives attraction to the biology behind long-term bonding, we explore the fascinating mechanisms behind one of humanity’s most powerful emotions. Together with my friend Alejandra, we break down the stages of love—lust, attraction, and attachment—and discuss the roles of hormones like oxytocin, vasopressin, and dopamine in shaping how we connect with others. We also touch on the physical effects of love and how heartbreak can feel like real, physical pain. Whether you’re curious about why you get butterflies or how love helps us thrive, this episode offers both a deep dive into the science and a personal touch.
