Publisher Description
An illuminating investigation of core body temperature regulation and its powerful effect on human civilization.
A hot cup of tea, coffee, or cocoa is calming and comforting—but how can holding a warm mug affect our emotions? In Heartwarming, social psychologist Hans Rocha IJzerman explores temperature through the long lens of evolution. Besides breathing, regulating body temperature is one of the most fundamental tasks for any animal. Like huddling penguins, we humans have long relied on one another to maintain our temperatures; over millennia, this instinct for thermoregulation has shaped our lives and culture.
Temperature contributed to our evolution—our upright walking, our loss of fur, and our big brains—and now continues to affect our lives in unexpected ways, and the link from a warm mug to our emotions is anything but straightforward. Studies have shown, for example, that a chilly deliberation room can predispose a jury to convict and that a cold day can make us more likely to buy a house. Our mind-body connection works the other way, too: thinking about friendly or caring people can make us feel warmer. Understanding how we subconsciously strive to keep our temperature in an optimal range can help us in our relationships, jobs, and even in the world of social media.
As IJzerman illuminates how temperature affects human sociality, he examines fascinating new questions: How will climate change impact society? Why are some people chronically cold, and others overheated? Can thermoregulation keep relationships closer, even across a distance? The answers offer new insights for all of us who want to better understand our bodies, our minds, and each other. Heartwarming takes readers on an engaging journey through the world, seen from the perspectives of coldness and warmth.

Ijzerman, an associate professor of social psychology at Universit Grenoble Alpes, debuts with a scattershot study of the concept of social thermoregulation: the idea that social connections have a physiological benefit in maintaining a person's core body temperature. Thermoregulation, he argues, "reconciles the divorce of mind from body by yielding a profound insight into what it means to be human," further claiming that one's psychology can influence physical temperatures and vice versa. Colloquialisms (calling people "warm" or "icy") can influence human bodies as well, Ijzerman writes, and taking a warm cup of coffee from someone can "prompt an increased judgment of social warmth." The effect of holding beverages reappears frequently in the studies recounted throughout, though Izjerman admits results have often been inconclusive or nonreplicable, and he writes that "only a single project exists to demonstrate a relationship between network diversity and human core body temperature." Even with this acknowledgment, he overreaches, such as when he interprets modern competition for fuel sources as being primarily about thermoregulation, or suggests that in the near future people will be able to use thermoregulation to "improve the quality of their close relationships." There is much that may prove intriguing to practitioners of psychology or to the interested layperson, but less that is truly convincing.
