Usually when I'm cold, my fingernails turn blue, the colder I am, the bluer they get. Is this something normal?

This is normal. Your body is shunting blood away from your extremeties towards your core (your torso and brain). This is what your body is supposed to do.

That's just your circulation slowing and your body them shunting blood away from your extremeties towards your heart/torso. The less you weigh and the health you are currently in play a large factor in this. You should NOT be still having issues from it if it's well after a couple of days post donating. If that's the case, go to your dr. Make sure you get plenty of warm drinks (hot chocolate is my fave) and warm blankets. For me, I have Raynaud's Syndrome so it happens ALL the time, even when I'm sleeping. I regularly donate blood and have donated plasma before.

It is kind of normal. The circulation stops as a reaction to the cold. The blue is from lack of oxygen, but it is OK because when the flesh is cold, it won't spoil. As long as the fingers stay above freezing for a short time it is probably ok. Wear gloves or put your hands in your pockets or next to your body.

Blue fingernails - the medical term is cyanosis - can also be due to low hemoglobin, the carrier of oxygen in red blood cells. Normally, arterial blood is bright red, thanks to the oxygen it contains. Your skin color, including the skin under your nails, is a combination of your skin pigmentation plus the color of your blood. When oxygen levels decline, blood turns blue-red. Chronic cyanosis can be a sign of many different lung and breathing problems, including asthma, emphysema, chronic obstructive pulmonary disease, chronic bronchitis and other respiratory disorders. It also can be a sign of a number of heart problems, as well as a response to high altitude and overdoses of certain drugs (narcotics, benzodiazepines, and some sedatives).
If your nails remain blue, I suggest having a medical checkup to identify the underlying cause. Your physician will probably want to do some tests to check your heart, lungs and hemoglobin.

This happens because your warm, oxygen rich red blood stays in closer to your core to keep your organs warm. The blood flow doesn't keep the extremities warm at that point. Wear some gloves!

Have you been playing out in the snow without your mitts again?
Seriously though ... . Sounds like you have what could be a serious circulation problem. Might want get that checked out by a doctor. I am the Ice Queen and even I don't get that.

it is not your fingernails.. it is the skin under them. That is merely circulation cutting down the blood flow to your fingers to keep the middle of your body with the organs and vital parts warmer... it is a normal thing. If they get to blue, that is bad.. you need your fingers, lol

Its normal for your capillaries to constrict in the cold. Do they pink up when your warm?
