The Science of Love

Listen Now

Why does the high of falling in love trigger sweaty palms, a racing heart, and rapid breathing? Why do some people attach easily after a few dates, while others run away quickly chasing new prey? Ryan Warner talks to Dr. Bridget Coughlin about what drives those impulses and reactions, in other words, the science of love. Dr. Couglin is a biochemist and curator of human health at the Denver Museum of Nature and Science.
