How much the heat affects the burning of calories when exercising. Am I burning many more calories when I am jogging in the middle of summer as oppose to when I run indoors during the winter.

The question is asked by Quinn (IP 64.110.240.81) from Canada

When you exercise, muscles are heated and more than 75 percent of the energy produced is lost as heat. The heart pumps hot blood from the muscles to the skin to dissipate the heat energy by evaporation. The heart has also to pump extra blood to supply oxygen to the muscles. These actions result in burning of calories. On the other hand, when you exercise in cold weather the calories burned are comparatively less because the heart, in this case, hasonly to provide oxygen to the muscles.

Warning: You should keep in mind that during exercise, if your the body temperature rises too high, you can develop heat stroke. At body temperature above 102 deg F, the muscles start to burn. At temperature above 105 deg F, conditions such as headache, blurred vision, ringing in your ears, dizziness, nausea may develop. To prevent it drink lots of water during and after exercise.
