...WINTER WEATHER AWARENESS IN THE MID SOUTH...

TODAYS TOPIC IS FROSTBITE AND HYPOTHERMIA.

FROSTBITE CAUSES NUMBNESS AND WHITE OR BLUE TINTED SKIN AND OCCURS
MOST COMMONLY IN THE FINGERS...TOES...EARS...AND NOSE.

HYPOTHERMIA...AN ABNORMALLY LOW BODY CORE TEMPERATURE...IS CAUSED BY
PROLONGED EXPOSURE TO COLD. HYPOTHERMIA CAN OCCUR INDOORS AS WELL AS
OUTSIDE. BODY FUNCTIONS SLOW TO A DANGEROUSLY LOW LEVEL. SYMPTOMS
INCLUDE SLURRED SPEECH...INCOHERENCE...DROWSINESS...POOR
COORDINATION...A SLOW HEART BEAT...UNCONTROLLABLE SHIVERING OR NO
SHIVERING AT ALL.

TO AVOID HYPOTHERMIA...KEEP YOUR CLOTHES DRY. WET CLOTHING LOSES
ALL INSULATING VALUE AND SHOULD BE CHANGED AS QUICKLY AS POSSIBLE.

MITTENS AND A WARM HAT ARE NECESSITIES. THE BODY LOSES ABOUT 50
PERCENT OF ITS HEAT THROUGH THE HEAD...SO WHETHER YOU ARE OUTDOORS
OR INSIDE AN UNHEATED HOME...DAY OR NIGHT...A HAT WILL GO A LONG
WAY IN HELPING YOU STAY WARM.

WIND CHILL IS BASED ON THE RATE OF HEAT LOSS FROM EXPOSED SKIN CAUSED
BY THE COMBINED EFFECTS OF WIND AND COLD. AS THE WIND INCREASES...
HEAT IS CARRIED AWAY FROM THE BODY...DRIVING DOWN THE BODY
TEMPERATURE. REMEMBER THAT ANIMALS ARE AFFECTED BY WIND CHILL AS
WELL.

AVOID OVEREXERTION...SUCH AS SHOVELING HEAVY SNOW OR WALKING IN DEEP
SNOW. THE STRAIN FROM THE COLD AND HARD LABOR MAY CAUSE A HEART
ATTACK. WEAR LOOSE...LIGHT-WEIGHT...WARM CLOTHING IN SEVERAL LAYERS.
TRAPPED AIR IS AN INSULATOR. LAYERS CAN BE REMOVED TO AVOID
PERSPIRATION AND SUBSEQUENT CHILL. OUTER GARMENTS SHOULD BE WATER
REPELLENT AND HOODED. ALWAYS COVER YOUR HEAD...AS YOU CAN LOSE HALF
OF YOUR BODY HEAT THROUGH AN UNCOVERED HEAD. BE PREPARED FOR THE
STORM BY LISTENING TO NOAA WEATHER RADIO...COMMERCIAL RADIO OR
TELEVISION FOR THE LATEST WINTER STORM ADVISORIES.
