There is new research on a method to combat diabetes and obesity, and you won’t need a pharmacy card or a gym membership to give it a try—just permission to mess with the bottom line of the utility bill. A new study, “Healthy Excursions Outside the Thermal Comfort Zone,” shows that dropping your building’s temperature below the comfort zone (21-22 °C; 69.8-71.6 °F for you Americans) can increase metabolism and energy expenditure. Mild cold, specifically, can increase glucose metabolism and was shown to increase insulin sensitivity by 40% in patients with Type 2 diabetes over a 10-day period. “This is comparable with the best available pharmaceutical or physical activity therapies,” according to the study. So…go adjust your coworker’s thermostat. They can thank you later.
