Avoid overexertion.
Cold weather itself, without any physical exertion, puts an
extra strain on the heart. If you add to this the strain of
heavy physical activity such as shoveling snow, pushing an
automobile or even walking too fast or too far, you risk damaging
your body.
Dress warmly
in loose-fitting, layered, lightweight clothing. Outer garments
should be tightly woven and water repellent. Wear a hat. Protect
your face and cover you mouth to protect your lungs from very
cold air. Wear mittens instead of gloves -- they allow your
fingers to move freely in contact with one another and will
keep your hands much warmer.
Watch for frostbite
and other symptoms of cold--weather exposure. Frostbite causes
a loss of feeling and a white or pale appearance in extremities
such as fingers, toes, tip of nose, ear lobes. If such symptoms
are detected, get medical attention immediately. Do no rub
with snow or ice -- this does not help the condition and,
in fact, will make it worse. The best treatment for frostbite
is the rewarming of the affected tissue.
Avoid alcoholic
beverages. Alcohol causes the body to lose its heat more
rapidly -- even though one may feel warmer after drinking
alcoholic beverages.
Keep yourself
and your clothes dry. Change wet socks and all other wet
clothing as quickly as possible to prevent loss of body heat.
Wet clothing loses all of its insulating value and transmits
heat rapidly.
When the body begins
to lose heat faster than it can produce it, a condition called
hypothermia begins to develop. The symptoms become very apparent,
and include:
- Uncontrollable
shivering
- Vague, slow,
slurred speech
- Memory lapses;
incoherence
- Immobile, fumbling
hands
- Frequent stumbling;
lurching gait
- Drowsiness
- Apparent exhaustion;
inability to get up after a rest
If a person shows
any signs of overexposure to cold or wet and windy weather,
take the following measures -- even if the person claims to
be in no difficulty. Often the person will not realize the
seriousness of the situation.
- Get the person
into dry clothing and into a warm bed or sleeping bag with
a "hot" water bottle (which should actually be
only warm to the touch, not hot), warm towels, heating pad,
or some other such heat source.
- Concentrate
heat on the trunk of the body first -- that is, the shoulders,
chest and stomach.
- Keep the head
low and the feet up to get warm blood circulating to the
head.
- Give the person
warm drinks.
- Never give the
person alcohol, sedative, tranquilizers or pain relievers.
They only slow down body processes even more.
- Keep the person
quiet. Do not jostle, massage or rub.
- If symptoms
are extreme, call for professional medical assistance immediately.
