Cold hands - illnesses as a cause

Circulatory disorders as a cause

If the hands are constantly cold, it is likely that a disease is behind the symptoms. One possible cause may be a circulatory disorder. The most common reason for a circulatory disorder is arteriosclerosis. In doing so, blood fats, blood clots or connective tissue accumulate in the vessels and narrow them. However, arteriosclerosis rarely occurs in the arm vessels.

In addition to arteriosclerosis circulatory disorders may also be caused by pressure damage to nerves and blood vessels or by an inflammatory vascular disease (thrombangiitis obliterans). Closures on the small arteries in the hands and feet are particularly common.

Raynaud's syndrome

Often the Raynaud's syndrome is the result of such a closure. This is an extreme form of circulatory disorder, in which the hands and feet are bloodless and thus white and completely numb due to a sudden vascular spasm. Then the hands turn blue and finally red. In the long term, Raynaud's syndrome can damage the vessel walls or cause the tissue to die.

Low blood pressure and heart failure as the cause

Often low blood pressure is the cause of cold fingers. If the blood pressure is low, the vascular walls pulsate only slightly and the parts furthest away from the heart are poorly supplied with blood. This lack of care particularly affects the hands, which therefore cool quickly. Low blood pressure is noticeable in addition to the cold hands through fatigue and concentration problems.

Low blood pressure either results when the vessels do not contract sufficiently or when the heart is not strong enough. If heart failure (heart failure) is present, less blood is pumped into the circulation. This, too, can cause the hands to be less well supplied with blood and cool.

In addition, tumors can also provide for cold hands. Both benign and malignant tumors can interfere with blood circulation by pressing on the vessels. The constricted blood flows less and our hands are supplied with less heat.

Hypothyroidism as a cause

If there is a disturbance in the hormone system, it can influence our vascular circulation and thus provide cold hands. For example, people who suffer from hypothyroidism freeze very easily. Because the thyroid hormones affect, among other things, our circulation and our sensation of warmth and cold. In the long term, hypothyroidism may increase the risk of arteriosclerosis and other vascular diseases.

Autoimmune diseases as a cause

Autoimmune diseases are diseases in which the body's own tissue is not recognized by the immune system and fought against as a foreign body. Among the autoimmune diseases include the connective tissue diseases that represent a possible cause of cold hands.

For example, in scleroderma, the connective tissue is getting thicker. This can lead to vasoconstriction, which then have a deteriorated blood circulation. Typical signs of scleroderma are swollen and stiff hands and feet. At a later stage, the face can be affected, which manifests itself in a rigid facial skin. Often scleroderma also causes Raynaud's syndrome.

Another autoimmune disease that can cause cold hands is rheumatoid arthritis. In this form of inflammatory joint disease, especially in the early stages, in addition to painful finger and ankle joints, a feeling of coldness in the hands and feet can occur.

Mental causes

Our psyche can also affect our hormone balance and thereby affect the blood flow in our blood vessels. So everyone probably knows the feeling of getting cold hands with excitement. In moments of particular tension, increased circulation of the hormones adrenaline and norepinephrine influences vascular dilation and thus blood circulation.

Even people who suffer from depression often have cold hands or cold feet. Due to the depressive mood, the hormone release and the activity of messenger substances in the brain can change. This can have effects on a wide variety of bodily functions, including blood circulation and temperature sensation.
