Lower home temperature in winter is associated with lower waist measurement — ScienceDaily.

“Although cold exposure may be a trigger of cardiovascular disease, our data suggest that safe and appropriate cold exposure may be an effective preventive measure against obesity,” said the study’s lead investigator, Keigo Saeki, MD, PhD, of Nara Medical University School of Medicine Department of Community Health and Epidemiology, Nara, Japan.

Our guess is “more often cold” has a lot of benefits we’ll be hearing about soon, however, hard to convince people to take cold showers and jump in to cyro chambers all the time.
