Does temperature have any effect on calories burned

I was just pondering whether the temperature has any effect on the amount of calories you would burn when doing excercise.
Would you burn more when it is hot and your body is working hard to keep its core temperature down. Or would you burn more if it's cold outside and you have to pump more blood to the extremities to keep them warm?
Taking all other factors into account, i.e. you maintain a good hydration level in the heat, do you think there would be any difference?

Yes, probably, but how much is anyones guess.0

I think very cold rides would increase calories burnt. Too much heat is probably self governing and so unlikely to affect things much.0

Agreed, I always thought that cold weather increased calorie burn as the body tries to maintain core temp. Hot weather results in sweat and loss of salts rather than calorie burn as far as I know...Do not write below this line. Office use only.0 -

Do you ride naked in cold weather or something? No. You ride bundled up - thus more or less negating the effect of the cold weather.
And don't you still sweat on cold weather rides?
I can see how cold weather would offer additional cooling of (some) hot weather rides, but the addition or subtraction of clothing would largely negate the effect of the outside weather.
(I think you're agreeing that weather doesn't affect calorie burn all that much?)0 -
The very fact you feel cold on your face (which I can't cover completely!) and are aware of cold generally is a stress factor for your body which makes your body turn up its calorie burning automatically. You can only bundle up so much anyway - well I can - as being enclosed in a boil in the bag effect is awful - and bad for the skin condition I have0

Cold rides make it harder to ride at the same pace tho. I'm proper slow in winter conditions.0

all things being equal, if you did exactly the same amount of physical work then you would burn more in hot conditions due to the energy requirements of sweating, hyperventilating etc to keep cool. During cold conditions (mod-hard) exercise is sufficient to keep body temperature up...indeed this is an well known Army survival technique for arctic conditions. However there is a big catch which is the amount of calories burnt is strongly related to the intensity x duration of exercise. So if the hot temp inhibited the longer workout any gains would be washed out. Best advice is to exercise in the most comfortable conditions possible to get most out of the ride.0

Also consider that in winter you're having to work against restrictive clothing and that if you wear too much you'll sweat more, get damp and then likely chill, particularly if going for more that 3-4 hours. Provided you can keep yourself hydrated, then you'll always be quicker when it's hot, air density is less too.Make mine an Italian, with Campagnolo on the side..0

Colder the more burned.
Guy i used to know was a trainer. He'd say to people, want an easy way to burn more calories? Drink ice cold water all the time. The body has to burn more cals to get the water you drink up to temperature.
He was a bit thick, so his recommendation is problably not brilliant, but i can see the logic.
Same thing would happen with cold air. Body needs to work harder to keep the lungs etc up to temperature.0
