There are many different factors that can affect your metabolism (the amount of calories used or burned). Your core body temperature can increase or decrease your metabolism or calories burned. There was research published in Transactions of the American Clinical and Climatological Association, 2009, that reports that an increase in body temperature is associated with a higher metabolism. And higher body temperature means a sped up metabolism. They suggest that for each degree Celsius temperature rises, your metabolism rises by 10 to 13 percent. That means you would burn an extra 100 to 130 calories per day if you were eating 200 calories daily. Your body temperature accounts for 50 percent of your energy expenditure.
According to a text paper, “Thermal Effects on Cells and Tissues”, your BMR changes as a function of temperature. Your BMR will change by 7 percent for each change of +0.9 degrees Fahrenheit. So when external temperatures warm up, you will burn more calories.
Exercise causes an elevation in your body temperature and an increased metabolism during such time because of two main causes. You are using lean tissue, muscle, and your temperature has increased, causing you to burn more calories / fat. “Exercising in hot weather burns more calories than working out in cooler temperatures because it takes more energy to cool your body in the heat”, reports the American Council on Exercise (ACE)
