Raynaud's (Ray-Nohs) is when the body contracts the blood vessels to preserve heat for the core, limiting blood flow to the extremities.
What does it affect?
Raynaud's only affects the circulatory system because it limits the blood flow. The circulatory system is responsible for circulating the blood through the body.
Who does it effect?
Woman are more likely to have Raynaud's than men. People who are between the ages of 13 and 15 years old have a greater chance of getting Raynaud's, but anyone can get it. You can also be born with it. If you live in a place with a colder climate have a bigger chance of symptoms.
As the extremities start loosing the circulation, they turn a light blue. As the symptoms get worse the fingers and toes, they turn white. As blood and heat returns (from going inside or another warm place) they turn red.
There are two types of Raynaud's. Type one has no effect on how long you will live. You will just be colder in a cold area. Type two is linked with other diseases. If you have type two you can die from the other disease but not from Raynaud's itself.
If you have type two Raynaud's there are medications you can take to lessen the chance of getting another disease. There are different triggers that start the symptoms. The most common trigger is cold. If cold is the trigger, wearing warm mittens and socks can help make the symptoms less severe. Another trigger is anxiety or stress. Avoiding cigarettes and caffeine will help.
Lowering or raising you core body temperature will cause the heart to beat faster, improving circulation. If you go to a sauna or a steam room will work and will also make the symptoms less severe.
