Raynaud's Phenomenon This response uses a complex system of nerves and muscles to control blood flow through the smallest blood vessels in the skin. In people with Raynaud's phenomenon, this control system becomes too sensitive to cold and greatly reduces blood flow in the fingers and toes. Blood flow can also be reduced by adrenaline that is released during times of high stress or anxiety.

- email. Knowledge center. Raynaud's disease, also known as Raynaud's phenomenon and sometimes simply Raynaud's, is a condition that causes some areas of the body to feel numb and cool in response to cold temperatures or emotional stress, caused by a problem with the blood supply to the skin.ome people who work in the plastics industry develop Raynaud's type symptoms. Smoking-smoking causes the blood vessels to narrow, increasing the risk of developing Raynaud's disese.

Overview Blood vessels in spasm. With Raynaud's, arteries to your fingers and toes go into vasospasm when exposed to cold or stress, narrowing your vessels and temporarily limiting blood supply. Over time, these small arteries may thicken slightly, further limiting blood flow. Cold temperatures are most likely to trigger an attack.

Raynaud's Phenomenon Raynaud's phenomenon is a condition resulting in discoloration of the fingers and/or the toes after exposure to changes in temperature (cold or hot) or emotional events. Skin discoloration occurs because an abnormal spasm of the blood vessels causes a diminished blood supply to the local tissues.
