Summer is starting and things are heating up. And in some places temperature is exceeding human capacity for existence. What you may not realize is it is a lot harder to cool down than to warm up. And warming up is something that gets at the heart of human social behavior.

Here to explain more about what this means is Dr. Hans Ijzerman. He is an Associate Professor of Psychology at Universitét Grenoble Alpes and a junior member of the The Institut Universitaire de France. And he wrote a fascinating book, Heartwarming: How Our Inner Thermostat Made Us Human.

We also get a sneak peek into how he and his lab are expanding their research into how temperature is influenced by culture, behavior, and biology.
