The holidays are supposed to be a time of joy. But all too often, the darker, colder days of winter, and even the stress of preparing for the holidays themselves, can lead people to feel something else: rushed, stressed, lonely, or even hopeless. How can you make sure this year is bright? Science shows that there's a wisdom to parts of traditional winter celebrations – a wisdom that's been honed over centuries to help us all find light, joy, and connection during the darkest and coldest time of the year.  Join Dave as he chats with Laurie Santos about how to unpack the psychological secrets of celebrations from Christmas, to Hanukkah, to Yule, and more. They’ll also discuss how we can put that wisdom into practice, whatever our beliefs, to make this season a happier and healthier one for all. Laurie Santos hosts the podcast The Happiness Lab and is a Professor of Psychology at Yale, where she teaches the most popular class in the university’s history.
