Cold Sensitive Skin
Winter
is around the corner, and its uncomfortable chill can cause physical damage as
well as dampen ones spirits. Here is
information about cold sensitive skin ailments; what to look for and what you
can do to avoid their numbing effects.
Raynaud’s
Disease
·
Raynaud’s disease and its symptoms turn up when the temperature turns down. Hands and feet are extremely sensitive to the
cold and become affected when the small arteries that supply these extremities
with blood and oxygen constrict or tighten.
The decrease in blood flow can cause the fingers or toes to turn white
or blue. Tingling and then swelling may
occur and become painful. If allowed to
continue, ulcers may form which further damage the tissue and produce chronic
infection around the nails of the fingers or toes.
·
Raynaud’s symptoms are brought on by sudden exposure to cold or
stress. Perhaps you’ve reached into the
freezer to remove tonight’s dinner only to discover that Raynaud
has become an uninvited guest.
·
The symptoms of Raynaud’s may be associated with an underlying cause
such as a connective tissue disease, or, in some people, they may occur with no
identifiable underlying cause.
Chilblains
& Trench Foot
·
Chilblains result from exposure to dry
cold that does not freeze the skin. You may notice that affected areas turn
reddish-blue and become swollen.
Chilblains are itchy and sometimes painful. In time, blisters containing clear fluid may
form. No permanent damage results,
however, injured areas may be more sensitive to future cold.
·
Damp cold at temperatures near freezing can result in trench foot (or immersion injury). This
may occur when a glove or sock becomes wet while out in the snow. The symptoms
of trench foot are similar to those of chilblains, but the damage is usually
more serious. The blisters are deeper
and look more like those from burns. As
with chilblains, there is no permanent injury other than increased cold sensitivity.
Frostnip &
Frostbite
·
Frostbite occurs when the injured
area freezes. Ice crystals form within
the cells of the skin leading to their rupture and death.
·
Frostnip is a first-degree frostbite where only the surface of the skin is
frozen. Similar to chilblains, frostnip
results in itchy and painful skin, but does not lead to permanent damage.
·
If freezing is allowed to continue second or third-degree frostbite
injuries may result in serious and long lasting damage.
Anybody
can be affected by the cold, but those most likely to suffer injury are the
young and the elderly. The best way to
prevent cold injury is to dress warmly and move indoors once your fingers or
toes begin to feel cold. Insulated
mittens work better than gloves. Always
keep your hands and feet dry and your ears covered.
Be
aware that alcohol and certain medications may cloud your judgment. It’s important to know when it’s time to come
in from the cold.
