Heartwarming: How Our Inner Thermostat Made Us Human

Heartwarming: How Our Inner Thermostat Made Us Human

Today we're talking about something most of us don't think about day to day: our inner thermostat. Now, what does that mean?! Were talking about thermo-wellness, thermoregulation, our sense of temperature, and how it relates to emotions. It's not new science, but it is the focus of a new book Heartwarming: How Our Inner Thermostat Made Us Human. 

Well, Hans IJzerman Ph.D. is here to talk all about temperature regulation and its importance on interpersonal relationships. He is the author of Heartwarming: How Our Inner Thermostat Made Us Human, and an Associate Professor at Université Grenoble Alpes. 

Central heating and how it has changed our lives, hot blankets and loneliness, describing people as having "warm or cold" personalities, and should you sell your house in the summer or winter months? We'll talk about all of this and more in this fascinating episode.

From February-April 2015 he was a fellow at NIAS. His work-in-progress can be followed at PsyArxiv. IJzerman was trained in social psychology, both in his Ph.D. at Utrecht University, as well as his Research Master's Degree at VU University. He received his Ph.D. in November 2010 on the topic of "Grounding Social Relations". In 2015, the Association for Psychological Science recognized IJzerman with the title of "Rising Star in Psychology" for his work on social thermoregulation.

In the last few years, he has worked with computer scientists to develop algorithms to record and detect infant crying. In 2015, he was trained in the Strange Situation Paradigm. His team is now working on developing sensor technology to measure skin temperature regulation within close relationships.

In addition, he is involved in large-scale collaborations to improve the state of science. He was a co-founder of the Collaborative Replication and Education Project (CREP) and currently serves as associate director of the Psychological Science Accelerator. IJzerman has a strong interest in replication and open science, and in letting theory benefit society, as he does with relationship therapists (, and with the In-Mind Foundation (
