Extreme winter temperatures can be just as dangerous as Houston's famous summertime heat.

"Even a short exposure, if you're not prepared for the elements, you can see changes from hypothermia or from frostbite within 20 to 30 minutes," said Dr. Jamie Kalantar with St. Luke's Episcopal Hospital.

Some of the warning signs of hypothermia include: shivering, confusion, and drowsiness, which can mimic the effects of being drunk.

Hypothermia is a serious medical emergency that requires immediate attention.

But preventive measures can help most people stay out of the emergency room.

"Bundling up, uh, having the heater on, cuddle up with my dog," said R.J. Rancon, its how he planning to stay warm.

Others Houstonian had this advice.

"Just drink coco and stay inside," said Cheryl Henderson.

It may be bone-chillingly cold in the Bayou City, but it down right warm compared to other parts of the country.

"It's not that bad, you can always try go up to Montana or something," said Rancon.

Right now it's negative 19 degrees in the Big Sky state of Montana.
