Increasing the Indoor Temperature during Winter Time Increases the chances of Obesity.

An experiment done by Johnson, Mavroggiani, M. Ucci, A. Vidal-Puig, and J. Wardle suggests that,”Reduced exposure to seasonal cold may have a dual effect on energy expenditure, both minimizing the need for physiological thermogenesis and reducing thermogenic capacity.”

The authors also discuss the role of brown adipose tissue (brown fat) in human heat production. Brown fat has an ability to burn energy and create heat unlike white fat, and its development in the body is triggered by exposure to low temperatures. Recent studies suggest that increased time spent in warm conditions may lead to a loss of brown fat, and therefore reduced capacity to burn energy.
