Dress warmly, or catch cold. Myth or Reality?

"Dress warmly, otherwise cold" - said the grandmother often. But scientists do not see a direct connection between these two events.
Although the word "cold" points us to a lower temperature ("frost"), as well as in other languages: German Erkältung (cold) comes from the word cold - kalt, in English the word "cold" and "cold" - cold, cold in Spanish - resfriado, from the word "freeze» - tener frio. It is therefore not surprising that the idea of the need to dress warmly, otherwise you will overtake the common cold, is firmly rooted in our minds. Still, the relationship between the cold and cold is not so straightforward.
One thing is clear - at low temperatures, work cells, tissues and organs slows down, which in turn may weaken the body.
In normal body temperature of about 37 degrees Celsius. Regulates body temperature by the brain - if we are hot, vascular signal is received from the brain, and they expand, if it's cold - narrowed. In other words, the main task of our body to maintain, if possible, a constant temperature, so that the heart and lungs working optimally.
If the body temperature is lowered still leads to circulatory deterioration, impaired communication between cells and organs. And how it can affect the immune system demonstrates a therapeutic technique used in cardiac arrest: to prevent damage to the brain, doctors have resorted to cooling the patient's body to 34-32 degrees. Studies have shown that such patients often develop pulmonary inflammation than those in which body temperature was normal poslereanimatsionny period.
"Nevertheless, it is not proven fact is that a slight hypothermia increases the risk of colds" - says Walter Haas from the Department of Epidemiology of the Robert Koch Institute in Berlin. "It is crucial only that there was a person in contact with the agents of the disease or not. If we talk directly about the cold, then there is a core group of pathogens - is rhinoviruses. They are the most frequent causative agents of colds from October to April. Besides the fact that the fall and winter viruses are more stable and thus more people sick. In winter, most of the time we're indoors at a large gathering of people, often use public transport. Therefore, the risk of contracting colds in winter increases dramatically and warm clothing is little that can be changed.
It is necessary to conduct a mobile way of life, spend more time outdoors, and it does not matter if your hands or feet a little cold, yet the mechanisms regulating body temperature is normal - there is no danger to our body.
The key to our health, especially in autumn and winter is a healthy way of life - fresh air, good nutrition, healthy sleep, non-alcoholic beverages and smoking. Try to wash your hands frequently, often ventilate the room and if possible to protect yourself from contact with people who are sick already.
Do not take antibiotics if you have a viral infection - in this case they are inactive. In this situation, you feel better to help a variety of teas, inhalations, baths (in the absence of elevated temperature). Cold lasts about seven days.
Thus, warm clothing and viruses, pathogens colds are interconnected indirectly.
