It sounds obvious, but keep your hands warm. Don't venture out into the elements without gloves or mittens -- look for cute styles that match, compliment or contrast with your coat. Keep your house warm enough or use a warm water bottle to keep your hands toasty while you snuggle under a blanket on cold nights.
Soak your hands in warm water to get blood flowing to your chilly hands. Afterward, slather on some thick lotion to relieve dryness and encourage circulation.
Stop smoking if you partake in the habit. If you suffer from Raynaud phenomenon, which can cause coldness and discoloration in your fingers, smoking can make it worse. You already know that smoking can take away from your beauty and health in other ways as well, so do yourself a favor and stop.
Swing your arms up and down to encourage blood to flow into your hands through centrifugal motion. Wiggle your fingers and rub your hands together.
Check with your doctor if you don't get any relief with home remedies, or if you have any other symptoms. Some conditions that can cause cold hands and fingers include anemia, diabetes and peripheral artery disease.
