You are in an overheated place and your hands are cold while the rest of your body is “hot”? This symptom probably hides a more serious health problem that requires extreme vigilance. Here are some explanations.
Cold hands? Beware of diseases that can hide behind this sign …
Having cold hands after spending the whole day in particularly cold weather is quite commonplace … Your limbs get colder than the rest of your body because there is less blood and heat sent to vital organs like the heart , brain, liver, etc.
But, conversely, if you are in a hot room and your whole body is boiling apart from your frozen hands, you may be suffering from a serious illness that requires immediate medical attention. .
Here are 10 diseases / factors that may explain why you still have cold hands
1. Raynaud’s disease
This condition affects the transport and circulation of blood in certain parts of the body, usually the fingers of the hands as well as the toes. Why ? Because the blood vessels in the fingers, feet, and sometimes the ears and / or nose shrink due to low temperatures or emotional stress. As a result, the fingers turn white or blue because of insufficient blood supply.
The causes of Raynaud’s syndrome are still unknown, but this disease can be easily identified: swollen fingers (often cold), pains, tingling. The good news is that this condition is more unpleasant than harmful to health.
2. An autoimmune disease
An autoimmune disease is an immune system disorder that attacks your tissues because of an inappropriate immune response from the body to certain substances. It can be serious, so if you notice symptoms similar to Raynaud’s syndrome, consult your doctor for further analysis. Once the true cause of your cold hands is diagnosed, you can more easily control the condition by taking the appropriate medications.
Cold hands are a very common symptom of dysfunction of the thyroid gland. This butterfly-shaped gland is located at the base of the neck, it acts as a thermostat inside the body.When it runs in slow motion, other bodily functions also slow down, resulting in signs such as fatigue, Obesity and the continual sensation of being cold … This thyroid disorder is very common from 50 years old.
4. Weakness of blood circulation
Most people think that poor circulation is one of the main reasons for cold hands. In fact, poor circulation occurs when the blood flow is reduced, when the pumping of the heart is not working properly or because of a physical obstruction of the blood flow (when the blood vessels are narrowed because of a rate high cholesterol).
When the blood flow in the body is disrupted, it is quite normal to feel coldness in the hands and feet, swelling and tingling are also common symptoms because the hands and feet are the most common parts of the body. more distant from the heart.
Anemia is a health condition that occurs when the body does not produce sufficient red blood cells or when the level of hemoglobin in the blood is low. Result: the body will have an insufficient oxygen supply, which can cause cold hands.
Anemia is usually due to iron deficiency, sudden loss of blood (menstruation in women), the presence of ulcers, certain types of cancer, etc.
Apart from cold hands, other very common symptoms may be related to anemia such as fatigue, headache, dizziness, shortness of breath and a certain pallor.
6. Vitamin B12 deficiency
Vitamin B12 is found in sardines, tuna, chicken offal, octopus, oysters, herring but also eggs, dairy products, etc. This vitamin is very important for the formation of red blood cells. A deficiency can lead to a decrease in red blood cells.
People over 50 and / or those who follow a vegetarian or vegan diet generally suffer from vitamin B12 deficiency. A simple blood test can clearly establish if you suffer from such a deficiency and if it is at the origin of your cold hands.
7. Low blood pressure
Low blood pressure may be related to dehydration, blood loss, use of certain medications or endocrine disorders (hormonal dysfunction). When the blood pressure is low, the blood vessels will no longer irrigate the extremities and leave the fingers and toes cold.
If you have low blood pressure with vision problems, feeling tired, nauseated, physically weak and confused, you should immediately consult your doctor.
8. The stress
Stress can cause many disorders and disrupt the functioning of the body. Indeed, a person subjected to conditions of intense stress and chronically will naturally secrete adrenaline, which will tighten the blood vessels in the extremities and cause cold hands and feet.
Many drugs can compress blood vessels, especially arteries. In this case, it is probably the side effects related to Raynaud’s syndrome.
10. Tobacco consumption
