BRISTOL, Tenn. -

With the very cold blast of winter weather coming, some people need to be aware of health concerns that come along with the Arctic blast.

Doctors at the Bristol Regional Medical Emergency Room say extreme weather can pose significant problems for the elderly and children because of their inability to maintain a core body temperature.

Also many times the elderly have pre-existing conditions or are on medications, but when it gets this cold everyone can be impacted if not prepared.

Staying out in the cold too long can result in hypothermia. It can cause shivering and confusion.  It can also cause hallucinations, but only in extreme cases.

Doctors says anyone experiencing these symptoms should reduce exposure to the cold, take off any wet clothing, and seek medical attention.

It's also a good idea to stay hydrated.
