Introduction. International Women's Day is celebrated in many countries around the world. It is a day when women are recognized for their achievements without regard to divisions, whether national, ethnic, linguistic, cultural, economic or political.
Raynaud's attacks usually affect the fingers and toes. Rarely, the attacks affect the nose, ears, nipples, or lips. During a Raynaud's attack, the arteries become very narrow for a brief period. As a result, little or no blood flows to affected body parts.
During an attack, symptoms of Raynaud's phenomenon can last from less than a minute to several hours. The period of exposure to the cold is extremely critical, because it only takes about 20 to 30 minutes of exposure to the cold to cause potentially serious problems, such as tissue damage.
