1. Bad spreading:
Sometimes the cause is as simple as the blood does not circulate properly to the fingers. Fortunately, it does not always respond to serious reasons and can be corrected by lifestyle changes.
Anemia, i. the low concentration of red blood cells in the blood is not a disease but a symptom of other pathologies or processes such as menstruation. Cold on the hands and feet is a symptom of anemia.
3. Blocked arteries:
the accumulation of fat in the arteries may interrupt blood flow to the limbs. Be careful because this can lead to a risk of cardiovascular disease.
4. Raynaud's syndrome:
is a vasospastic disorder that causes discoloration of the fingers. These spasms reduce the blood supply to the limbs. Stress and cold increase these symptoms.
This autoimmune disease affects the skin and the underlying tissues, such as blood vessels. The body produces excess collagen.
physical exercise favors the flow of blood so that excessive sedentary lifestyle can be counterproductive.
7. Addiction to Tobacco:
tobacco encourages narrowing and blockage of the arteries, which may, as we have seen before, favor the poor circulation of blood and cold hands.
When not treated well, diabetes affects blood circulation and blood reaches the ends properly.
9. Female sex:
A US study in 1998 showed that women's average hand temperature is 2 degrees lower than that of men due to hormonal causes.
the primary temperature increases in the early stages of pregnancy, and so some women notice that their limbs are colder.
