Turn Down Your Thermostat
Yes, shivering burns calories, but that's not the extent of it. When researchers in the Netherlands put a group of young men in a cold room for 10 days, the researchers noticed that after a few days the men stopped shivering. This likely was due to an increase in brown fat. Brown fat generates heat by burning energy. Scientists even believe that brown fat can use white fat (which is the stuff that accumulates around our middle) for fuel. A 2012 study published in The Journal of Clinical Investigation found that men exposed to cold temperatures — but not cold enough to induce shivering — for three hours burned 250 more calories.
