27 Feb Reynaud’s
Hands changing colour? Then read on!
When the weather is cold it is quite common for people to look more pale as blood leaves the skin and tries to keep our insides warm.
For some people though, the exposure to colder temperatures can cause a much more bigger reaction especially to there hands and feet causing them to go from white, to blue and then red.
This is known as Reynaud’s.
What is happening
The 3 colour changes are caused by excessive reduction in blood flow.
WHITE – There is less blood in that area
BLUE – The oxygen in the blood is low
RED – As the area is warmed up the blood vessels dilate and blood flow returns to the area carrying oxygen
Why it is happening
Primary Reynaud’s (Reynaud’s Disease) – has no specific cause but there may be links to hormones as well as people who smoke
Secondary Reynaud’s (Reynaud’s Phenomenon) – This is when it caused by another factor such as vascular or skin condition or environmental factor
Signs and symptoms
- Skin colour changes in order of white, blue and red especially in hands and toes
- Pain in hands when cold and tingling feeling when hands are warmed up

How to deal with it
- Wrap up prone areas prior to going out in the cold
