What it actually means if one of your fingers turns white when it's cold

Fingers Turn Blue or White When Cold? It Could be Raynaud’s

White fingers from Raynaud's syndrome

Do your fingers or toes have an extreme reaction to cold temperatures, changing colors and becoming numb or painful?

 If so, you could be part of the 5 to 10 percent of the population that suffers from Raynaud’s syndrome.

While not usually dangerous, this condition can be a frustrating nuisance.

And even though it’s relatively common, there is still little known about the condition’s causes and there is no cure.

Raynaud’s syndrome (also referred to as Raynaud’s disease or Raynaud’s phenomenon) more often affects people who live in cold climates, and women are nine times more likely than men to be affected.

 When a person with Raynaud’s syndrome is exposed to cold temperatures or stress, their blood vessels start to constrict, a phenomenon known as vasoconstriction, which prevents the blood from reaching the skin’s surface.

 It most often affects the extremities such as the fingers and toes.

When the blood vessels shrink, the skin may turn white, blue or purple.

Later, when the blood starts flowing again the skin may turn red and start to tingle or throb.

Some people can experience these effects when temperatures are as high as 60 – 70 degrees Fahrenheit.

What Causes Raynaud’s Syndrome?

Sometimes Raynaud’s syndrome develops for no obvious reason; this is known as primary Raynaud’s.

In contrast, secondary Raynaud’s is caused by an underlying condition, such as lupus, rheumatoid arthritis or other connective tissue diseases.

 It can also be caused by certain medications used to treat blood pressure, cancer, migraines and other conditions, as well as some over-the-counter cold and flu medications.

Raynaud’s Syndrome Versus Poor Circulation

Raynaud’s syndrome is a blood circulation problem, but it is different from what is commonly thought of as “poor circulation.”

Poor circulation generally affects older people and can be caused by underlying conditions such as plaque buildup in the arteries, high blood pressure, diabetes, obesity and heart and vascular issues, as well as lower activity levels.

Raynaud’s syndrome, on the other hand, can affect people that are younger and otherwise healthy.
