Hello Taushie,

According to the U.S. DEPARTMENT OF HEALTH AND HUMAN SERVICES the
medical condition you are referring to is Raynaud's Phenomenon.
Raynaud's Phenomenon is a Disorder of the small blood vessels that
feed the skin. During an attack of Raynaud's, these arteries contract
briefly, limiting blood flow. This is called a vasospasm. Deprived of
the blood's oxygen, the skin first turns white then blue. The skin
turns red as the arteries relax and blood flows again.
Extremities--hands and feet--are most commonly affected, but Raynaud's
can attack other areas such as the nose and ears.
These are the symptoms:
Symptoms include changes in skin color (white to blue to red) and
skin temperature (the affected area feels cooler). Usually there is no
pain, but it is common for the affected area to feel numb or prickly,
as if it has fallen asleep.
Causes:
Doctors do not completely understand the cause of Raynaud's, but they
believe the body's blood vessels overreact to cold. When the body is
exposed to cold, the hands and feet lose heat rapidly. To conserve
heat, the body reduces the amount of blood flowing to these areas by
narrowing the small arteries that supply them with blood. In persons
with Raynaud's, these small blood vessels overrespond to cold. For
example, reaching into a refrigerator may trigger an attack.
(..)
Women between the ages of 15 and 50 are most often affected, but
anyone can have the problem. It is not known for sure how many people
suffer from these symptoms, but Raynaud's is a common problem.
