Working in the cold, am I burning calories just keeping warm?


Quote  |  Reply
 I was stacking firewood pretty much all afternoon and it is freezing cold outside.  I am just wondering if I would be burning more calories working  in sub-zero temperatures than if it were warm out. Also along the same lines, If I sleep in a very cold room would I burn more calories while I sleep than I would normally burn sleeping in a warm room?

Yes, you are. The partial  reason why our bodies store fat is to insulate it and keep it warm. And the reason since I have lost some weight I now freeze more! (Less insulation) That would be an interesting bit of trivia to find out how many more calories one burned to keep warm wouldn't it? Anyone? Anyone?...

You do burn more calories in the cold but you also burn less calories exercising in the cold than you would exercising in the heat. This is because the heat generated from your work/exercise is relieved by the cold temperature.. you don't need to spend extra calories cooling yourself down.

However you are still better off exercising in the cold than doing nothing in the cold. Probably. =P 

haha that reminded me of a dream my fiance had! he had a dream that i was doing this new weight loss thing where i kept it freezing all the time so i'd burn more calories! i had convinced everyoen at work to turn the thermostat down so we could lose weight haha.

I don't agree. I challenge you to find some sort of written evidence that you do not burn as many calories in the cold. Sounds like hogwash to me. The very act of moving out in the cold keeps you warmer and burns calories...just because you might not sweat doesn't mean anything. It means your body is doing it's job. Why do you think we crave more calories in the winter? TO KEEP WARM. Yell

Get out in the cold

You burn more calories when it's cold outside. According to Andrew J. Young, Ph.D., of the U.S. Army Research Institute of Environmental Medicine in Natick, Mass., "There are two factors that could cause energy expenditure to increase with falling outdoor temperature. First, if shivering is elicited by cold, then energy expenditure increases. However, different people have differing shivering-response sensitivity, and intensity of shivering will be influenced by magnitude of decrease in body (deep core and skin) temperature, which in turn is influenced by body size and fat content that vary widely among people, as well as clothing worn." Additionally, there is a likelihood that you could have a slight increase in calorie burn (about 3 percent to 7 percent) from your body rewarming itself from cold air touching your skin and warming the cold air that goes into your lungs, adds Wayne Askew, Ph.D., a professor of nutrition at the University of Utah.

 

So, in effect, if you want to really burn more calories, take off layers of clothing and force your body to keep itself warm. THEN you WILL burn more calories. For sure.

OK, I have just developed a new work out routine, it's  5 below outside, who's up for a fifteen minute streak? LOL

3 to 7 %

If you burn 1,000 Calories in one workout you may burn an extra 30-70 calories.  That's not even enough Calories to burn off one Girl Scout cookie and background-noise for any average workout session of 300-500 Calories. 

For example, you'd have to run 10 miles plus to burn 1,000 Calories.

You'd be better off just taking one or two extra 20 minute walks per week for about 80 Calories per walk.  That's a lot more Thin Mints.

Just sayin. 

and it doesn't say anything about calories burned when you are exercising...I don't think anyone would argue against the fact that you burn more calories if you are shivering than if you aren't. but if you are exercising, which naturally warms you up, and you don't have to sweat to cool yourself down like you would in the heat...it seems to me like you would come out pretty even or maybe even down some cals. but i don't know for sure...thats just what would make sense to me.

A calorie is a unit of heat. When your body warms and gives off heat..and sweating while working out....you are expending calories. As far as the "It's only an apple or a cookie." comment....I guess then someone on a diet should go ahead and eat an apple or a cookie above their daily BMR....because it's no biggie, right? It all counts.

If you are cold, regardless of the temperature, your body will burn extra calories to generate heat to keep you warm.  If you are hot, regardless of temperature, your body will not burn extra calories to keep you warm, rather, it will perspire in an attempt to rid itself of the excess heat generated from exercise or work.
