A cold morning is bad enough -- but when it's windy and cold at the same time, you know it's going to be downright uncomfortable.

Meteorologists call this "wind chill," and if you thought it was only hype, think again.

Wind chill makes us feel colder than the actual temperature. This is caused by the interaction of air temperature and wind on the human body. Your body gives off heat constantly, but temperature and wind can make your body lose heat even more quickly. When the wind blows, it removes the layer of warm air around your skin, putting the full force of the frigid air in direct contact with your body.

As your skin grows colder, your body has to work harder to generate enough heat to prevent injury. The longer your body is exposed to the cold air, the harder it has to work.

The wind chill is always lower than the actual temperature. When the wind chill is below freezing, it can be dangerous for bare skin to be exposed for extended periods of time. Being exposed to extreme cold could lead to hypothermia or frostbite.

The best way to keep your kids safe as they head outside is to dress them in thin, warm layers. Start with a light base layer and add other warm, waterproof layers on top.

If you have to be outdoors for long periods of time, keep your arms, legs, fingers and toes moving to keep blood circulating. Stay safe this winter!
