Cold hands can be the result of a disease that compromises circulatory health. This time we review its possible causes.
To protect itself from the effects of low temperatures, the body naturally takes the warm blood from the extremities and carries it to the vital organs. However, some people find their hands cold, even when the temperature is normal. For what is this?
There are some underlying causes that could explain cold hands when cold weather is not the reason. Although it does not always indicate something serious, it sometimes warns circulatory difficulties, nutritional deficiencies or autoimmune conditions.
Main causes of cold hands.
People who perceive their cold hands at a time other than winter may be suffering from diseases that compromise their blood circulation. Of course, to confirm this, it is best to receive a medical diagnosis through relevant tests.
However, first of all, it is essential to note that this characteristic does not always indicate something serious. Each person feels cold or heat in a different way, so it is normal that many perceive more sensitivity to drops in temperature.
Now, if the symptom becomes frequent and is accompanied by fatigue, tingling and other discomfort, it should be given more attention. Some diseases begin to manifest with signs as subtle as this. Let’s look at the possible causes.
1. Hypothyroidism.
We have talked about hypothyroidism on numerous occasions. It is a disease of the thyroid gland, characterized by a decrease in the production of hormones. This effect, in turn, slows down the functions of the metabolism and triggers a series of symptoms.
For example, due to difficulties in transforming fats and sugars into energy, the person begins to gain weight. Also, circulation becomes uncontrolled and there are changes in skin, hair and body temperature. So, it can be the cause of cold hands.
2. Raynaud’s syndrome.
Although its name may alert patients, it is not an extremely serious ailment. Raynaud’s syndrome is a disease that affects the blood vessels in the fingers and toes, causing them to cool.
The attacks usually occur when there is exposure to cold temperatures, or due to high levels of stress. In addition to feeling cold hands, those with this problem may experience tingling, palpitations, and swelling.
What happens is that the arteries narrow, preventing blood from circulating properly. For this reason, the fingers change color, showing their bluish and reddish tips. As the crisis passes, circulation is restored and the hands return to normal.
3. Anemia.
One of the main causes of cold hands is anemia. It is a blood disease, in which the production of red blood cells decreases. It also occurs when red blood cells lack hemoglobin due to iron deficiency.
In addition to cooling the extremities, it often triggers symptoms such as extreme tiredness, excessive hair loss, and dizziness. All this happens because circulation is altered and, therefore, oxygen supply to the cells decreases.
Arterial diseases.
Diseases that compromise arterial health can be the trigger for decreased blood flow to the hands. This can be the consequence of a buildup of cholesterol plaque or inflammation of the blood vessels.
On the other hand, it can also occur due to more careful conditions such as primary arterial hypertension, which affects the arteries of the lungs. In both cases it is essential to do a medical follow-up for its control.
Carpal tunnel syndrome.
Cold hands that are accompanied by a feeling of tension and tingling can indicate carpal tunnel syndrome. This occurs when the median nerve, the one that runs between the forearm and the palm of the hand, is compressed at the wrist.
Its initial symptoms are mild, but gradually get worse. You may feel numbness in your hands and fingers, as well as pain when doing some movements. The most severe cases require surgical interventions to solve.
Cold hands are part of the life of those who live in cold environments. However, if they are accompanied by other symptoms such as pain, tingling or difficulty in movement, it is best to consult a doctor. They can almost always be alleviated with home treatments and lifestyle changes.
