Their article joins a growing body of research on the metabolic effects of cold exposure, some of which I’ve reported on previously. Earlier last year, in the journal Cell Metabolism, researchers from the National Institutes of Health likened these effects to those of exercise, arguing that a better understanding of endocrine responses to cold could be useful in preventing obesity. The lead researcher in that study, Francesco Celi, published more research in June, finding that when people cool their bedrooms from 75 degrees to 66 degrees, they gain brown fat, the metabolically active fat that burns calories to generate heat. (Having brown fat is considered a good thing; white fat, by contrast, stores calories.) Another 2014 study found that, even after controlling for diet, lifestyle, and other factors, people who live in warmer parts of Spain are more likely to be obese than people who live in the cooler parts.
