Blue nail beds can be a sign of a lack of oxygen in the blood, known as cyanosis. This can be caused by poor circulation, heart or lung conditions, or exposure to cold temperatures. It can also be a symptom of problems with haemoglobin, a protein in the red blood cells that is responsible for carrying oxygen.

What You'll Learn
Blue nail beds are a sign of poor circulation
Cyanosis can occur when the circulatory system is not carrying blood around the body as it should, resulting in poor circulation and a blue tinge. Cold weather can cause poor circulation temporarily, as the blood vessels narrow because of the reduced temperatures. They do this to prevent blood from reaching the extremities and to keep the internal organs at an optimal temperature.
Heart and lung conditions can also cause cyanosis, as can problems with haemoglobin, a protein in the red blood cells that is responsible for carrying oxygen. When a healthcare provider listens to your heart and hears a certain swooshing sound, it's an indication that the blood is flowing through the heart abnormally. Heart murmurs can be harmless, but they can also indicate a structural heart condition such as a hole between two or more of the heart's chambers.
Anyone with blue nails should seek medical advice.

Blue nail beds can be caused by heart conditions
Blue nail beds, or cyanosis, can be caused by a lack of oxygen in the blood. This can be the result of poor circulation, or a problem with the heart. Heart murmurs, for example, can cause blue nail beds. This is when a swooshing sound is heard when a healthcare provider listens to the heart, indicating that blood is flowing through the heart abnormally. Heart murmurs can be harmless, but they can also be a sign of a structural heart condition, such as a hole between two or more of the heart's chambers.
Blue nail beds can also be caused by lung disease, exposure to cold temperatures, circulation problems, issues with haemoglobin, and more. It is important to see a healthcare provider for blue nail beds, in order to determine the cause. In some cases, cyanosis may require immediate care.
