Do you burn more calories working out in the heat?

Thermal regulation....your body is in constant stress to provide stasis. If it is very hot outside, your body uses ENERGY to cool yourself down (vasodilation, sweating...etc)...these regulatory measures don't just happen out of nowhere, they need energy to happen...Energy = calories. Yes, there is absolutely no question your body uses more calories in hot (or cold) weather to try to maintain stasis. No, it is most likely not significant when considering it into your diet or routine.
