When it's cold, it freezes - this is a normal protective mechanism of the body. but unusual sensitivity to cold can also be a sign of infection, circulatory disorders and hormonal disorders.
With heat and Cold receptors in the skin (So-called thermo receptors) takes the body senses the outdoor temperature. If this falls, the receptors send signals to the brain. There, more precisely in the so-called hypothalamus, is the temperature center.
This network of nerve cells receive signals from the thermal receptors and evaluates them. So it can detect whether the current actual temperature of the body to the target temperature corresponds. If not, the temperature center can put the body into a state in which he generates heat, saves and focused on the vital organs. This is the state of the person concerned as "Freeze" true.
The human body functions optimally when the Core body temperature of about 37 degrees Celsius is. The temperature center in the brain ensures that the body does not deviate from this target value as possible. It gets amplified signals from the cold receptors, it sets in motion various processes to increase the body temperature. In short: It freezes.
When freezing the following happens:
How much someone freezes at a certain ambient temperature varies from person to person. Among other things, the cold sensitivity of a people depends on the Thickness of subcutaneous fat from. This isolates the internal organs and protects them against heat loss. That is why thin people freeze often faster than those who have more subcutaneous fat.
Even people with low blood pressure (Hypotension) are more likely to freeze and to cold feet or hands than people with normal or high blood pressure. Because the lower the blood pressure, the less blood reaches the small vessels in hands and feet.
Freezing and cold intolerance are no medical diagnoses, but may be symptoms of other diseases. Who has the impression unusually frequent and / or strongly to freeze, can ask your family doctor for advice.
The doctor explains, first, whether there be more complaints that could indicate the causative disease. He also may decrease the patient's blood. Certain blood tests (such as the thyroid values) can help find the cause of the constant freezing. There is suspicion of a specific disease (such as hypothyroidism), more tests may be needed.
A special therapy against freezing there is not any. Proven home remedies are warm clothing, blankets, hot drinks and exercise.
Is this a symptom, it is important to treat the underlying disease. People with an underactive thyroid, the doctor prescribes a rule thyroid hormones. In case of serious circulatory disorders, it is important that a doctor clarifies the complaints.
For colds and flu freezing disappears if the disease endured is. A therapy is oriented towards the exact cause of flu infection (e.g. viruses or bacteria).
