ST. LOUIS, MO (KTVI)-- The frigid temperatures are making it uncomfortable to step outside for just a short time.

For those that have to work outside, it can be downright dangerous.

When exposed to cold temperatures, your body begins to lose heat faster than it can be produced.

Prolonged exposure to cold will eventually use up your body's stored energy.

The result is hypothermia, or abnormally low body temperature.    

A body temperature that is too low affects the brain, making the victim unable to think clearly or move well.
