1.Reynaud’s Phenomenon

This phenomenon is when blood vessels in the hands and feet overacting to cold temperatures or stressful situations are a major cause of freezing hands and feet. It triggers arteries in fingers and toes to enter vasospasm or a condition that narrows your blood vessels and limits blood supplies to the extremities. Over time these arteries thicken which further limits blood flow. When this happens, it is called an “attack.” During an attack, the fingers and toes can change colors. They may go from white to blue to red. They may also feel cold and numb from lack of blood flow.

2.Autoimmune disease

Lupus may be a contributor to cold hands and feet. Blood vessels come under attack with systemic lupus. Small blood vessels in the skin of hands and feet and prevent normal blood movements. Icy hands and feet are the result.

3.Hypothyroidism

This is a condition in which the thyroid gland becomes under-active, failing to properly secrete the hormones that help convert food and oxygen into energy. It can be caused by autoimmune diseases, birth defects, radiation treatment, or the use of certain drugs like lithium. It can cause sensitivity to cold. A sluggish metabolic rate will slow down your body’s ability to produce heat. Cold hands and feet are a common symptom of slow thyroid function.

4.Problems with circulation

Most people think that the main reason for cold hands is this. Poor circulation occurs when the flow of oxygen-rich blood and nutrients decreased, due to poor heart pumping, and other reasons (cholesterol clogged blood vessels). When blood does not flow through the body as it should, you feel the cold in the hands and feet as the hands and feet furthest from the heart.

5.Anemia

Anemia occurs when the body does not have enough red blood cells or the hemoglobin in the blood is low. The result of anemia is reduced supply of oxygen the body which can cause cold hands. Some of the reasons for the reduced iron in the blood may be due to not getting enough iron diet, blood loss, for example due to the menstrual cycle, ulcer, gastrointestinal bleeding, cancer, or gastrointestinal disturbances such as celiac disease or Crohn’s disease. Apart from cold hands, anemia can cause fatigue, headache, dizziness, shortness of breath and pale skin. Most cases of anemia can be treated easily by entering the iron.

Vitamin B12, which is present in red meat, eggs, milk, and other dairy foods, is important for the formation of red blood cells. Lack of this vitamin leads to reduced production of red blood cells. Vegetarians or vegans, and people older than 50 usually lack this vitamin, because of their reduced ability to absorb it. If your body lacks vitamin B12 in your diet, add a variety of multi-vitamins and symptoms will disappear in a few weeks.

6.Low blood pressure

This can occur due to a number of reasons, including dehydration, blood loss, certain medications, and endocrine disorders. When blood pressure is low, blood vessels directing blood from the extremities to the vital organs, leaving fingers cold. If you have a low pressure accompanied by dizziness, fatigue, nausea and a feeling of weakness, to be sure to tell your doctor.

7.Stress

Stress is the cause of many problems in our body, so no problems with the arms are any exception. If you are exposed to chronic stress or anxiety, secretes adrenaline that restricts blood vessels in the extremities which cause cold hands and feet.

8.Medication

Some medications can cause cold hands. There are lots of drugs that constrict blood vessels, in particular arteries, and when this happens, the result is Reynaud’s syndrome. Some of these drugs are prescribed beta blockers to regulate blood pressure, certain drugs for cancer, and drugs for migraine and nose drops.

9.Smoking

If you do not have a good enough reason to quit smoking, this is one of them. The nicotine in cigarettes causes the blood vessels to close and leads the formation of plaque on them, resulting in reduced mobility and blood flow to the extremities.
