Does exercise in heat burn more calories?

Does exercise in heat burn more calories? The short answer is yes; when you train and it’s hot out, your cardiovascular system has to kick into overdrive to cool the body down and maintain a steady body temperature.

If you were to do the exact same exercise in a mild climate and a hot climate, the additional ‘cooling’ efforts from your body in the warmer environment would likely lead to a higher energy expenditure.
