Cold extremities occur when blood vessels are constricted or slightly obstructed. This may be due to increased connective tissue tension around the blood vessels, which causes a reduction in the passage of blood through the skin. The hands or feet may change color, from pink through purple, orange, and blue even to white. As they warm up again, the color changes back again in reverse order, often accompanied by a feeling of throbbing or buzzing.
A lot of us have cold hands or feet and simply put up with it. For some people it can be a serious problem – especially if they get very cold. Some people wear mittens and heavy socks all year round, even in warm weather, indoors and out. Their hands and feet are always cold. A number of things cause this, such as:
Some people's blood vessels are hypersensitive to cold and tend to go into spasm, a condition known as Raynaud's Syndrome. This is most common in young women. The fingertips, then the fingers and even the whole hand become cold and go white. They go numb and have difficulty doing fine movements. Sometimes the feet are also affected. In the most extreme of circumstances where for some reason the blood supply to an area is restricted for a prolonged period of time frost bite or gangrene can occur.
If wearing gloves and wool socks and staying indoors where it's warm is a nuisance or doesn't help, try these other warm-up tips:
In cold climates, cayenne powder can be used topically as well as internally. One-eighth of a teaspoon sprinkled into each shoe and/or glove acts to help the body generate heat. Water-soluble components in cayenne dilate capillaries in the skin surface, producing an immediate sensation of heat. Within 15 minutes, oil-soluble compounds reach deeper tissues, generating warmth for hours.
Gingko has an documented reputation for improving circulation, and is sometimes of help for cold hands and feet.
