Raynaud’s Syndrome
Raynaud’s (ray-NOHZ) disease or Raynaud’s Phenomenon is a problem with blood flow. It is a condition that causes some areas of your body––such as your fingers, toes, and the tips of your nose and ears––to feel numb and cool in response to cold temperatures or stress. In most cases, this inconvenience and discomfort last only for a short time, while your body is reacting to the coldness or stress. In Raynaud’s disease, the smaller arteries that supply blood to your skin narrow, limiting blood circulation to affected areas. This is more prevalent in women and people living in cooler climates that are 60 degrees or colder. It also happens quite frequently as the weather suddenly turns from fall to winter and the temperature drops.
