Why are we as humans more comfortable in 'colder' temperatures?

The human body runs between 98 and 99 degrees Fahrenheit, but most humans are uncomfortable if the air around them is much above 80.

Why is this?

Our *core* temperature is 98ºF. The temperature of our extremities is lower. 

Our metabolism would make us get dangerously hot if we couldn't dispel extra heat, and the easiest way to do this is to be in an environment that is significantly lower than our core temperature.

At higher temperatures, we have to rely on evaporative cooling. When the temperature and humidity are high, we are in danger of overheating.
