    Basically, the answers are we burn more calories in hot weather than cold and no, sweating doesn't burn more calories.

    Do You Burn More Calories in Hot or Cold Weather?

    You burn fewer calories when you exercise in cold weather than you do when it's hot. The hotter it is, the more extra work your heart has to do to prevent you from overheating. More than 70 percent of the energy produced by your muscles during exercise is lost as heat. So the harder you exercise, the hotter your muscles become. In hot weather, not only must your heart pump extra blood to bring oxygen to your muscles, it must also pump hot blood from your heated muscles to your skin where heat can be dissipated.

    On the other hand, in cold weather, your heart only has to pump blood to your muscles and very little extra blood to your skin to dissipate heat. Your muscles produce so much heat during exercise that your body does not need to produce more heat to keep you warm. So your heart works harder and you burn more calories in hot weather. This information should not discourage you from exercising when it’s cold, because staying in shape is a year-round proposition. However, it may help to explain why so many people find the pounds creeping on in the wintertime, even when they stay active.

    Do You Burn More When You Sweat?

    Your body creates sweat to cool you off when your body temperature gets too high. How much you sweat has nothing to do with how many calories you burn. What matters is how long and how intensely you're working out. Any weight loss that you experience immediately after a workout is only water weight, and you'll gain it right back as soon as you rehydrate yourself. So don't worry about not sweating. If you go for a 30-minute run and you haven't sweat a drop, you still burned almost 300 calories.
