Brown fat responsible for from heart disease-related deaths in winter
More people die from heart-disease during the winter months, and according to a new study published in the journal Cell Metabolism, the increase in mortality is possibly due to the accelerated growth of atherosclerotic plaque in the blood vessels caused by the activation of brown fat by the cold.It has long been known that the number of deaths from cardiovascular diseases increases during the winter. It has been speculated that this might be the result of over-exertion while shovelling snow and a general decrease in physical activity, although the underlying mechanisms have been unclear.
