The efficiency of the human body, like any other machine, depends on the surrounding temperature. We get exhausted quicker if we run on a hot summer afternoon than we would in the cooler evening. But how does the temperature influence our calorie burn rate?
In a cold environment the body will need to burn calories to produce additional heat, in a hot environment the body needs energy to cool the system. But is this significant during sport? Does it make sense to train in a hot or cold environment to increase the calorie burn rate or is it better to train in a more or less ideal environment?
