First, a quick science lesson on cold hands: “The body regulates the temperature of the hand mainly by controlling blood flow through the radial and the ulnar arteries,” Dr. Abayomi Ogunwale ...
The condition can cause localized pain, discoloration (paleness), and sensations of cold and/or numbness. When exposed to cold temperatures, the blood supply to the fingers or toes, and in some cases the nose or earlobes, is markedly reduced; the skin turns pale or white (called pallor) and becomes cold and numb.
[3] [4] Exposure to cold temperatures worsens the cyanosis, while it often improves on warming. [2] Aside from the color changes, patients normally are asymptomatic and therefore there is usually no associated pain. The most common sign, discoloration, usually is what prompts patients to seek medical care. [3] [4]
To warm your hands up, place “your hands in warm water for about five to 15 minutes” until the cold feeling has dissipated, Wright says. It’s important to note that treatment will vary ...
It was thought that the hunting reaction protected the fingers against cold injury and improved muscle function in the fingers. An experiment has shown cold acclimation minimizes the hunting reaction (reduced mean temperature of the digits and a prolonged time of cold exposure prior to initial vasodilation), thus putting the hand at a greater ...

Most often, frostbite occurs in the hands and feet. [7] [8] The initial symptoms are typically a feeling of cold and tingling or numbing. [1] This may be followed by clumsiness with a white or bluish color to the skin. [1] Swelling or blistering may occur following treatment. [1] Complications may include hypothermia or compartment syndrome. [2 ...
Cyanosis is the change of body tissue color to a bluish-purple hue, as a result of decrease in the amount of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. [1] Cyanosis is apparent usually in the body tissues covered with thin skin , including the mucous membranes , lips, nail beds , and ear lobes. [ 1 ]
