Husten, Schnupfen, Heiserkeit: Vor allem im Herbst und im Winter scheint eine Erkältung oft vorprogrammiert zu sein. Das in diesen Jahreszeiten oft nasskalte Wetter ist wie prädestiniert dafür, den Körper anfälliger für Angriffe auf das Immunsystem durch Infektionen zu machen, was eine Erkältung begünstigt.

Cough, runny nose, hoarseness: Especially during autumn and winter a cold often seems to be inevitable. The often cold and wet weather in these seasons is predestined for making the body more vulnerable to attacks on the immune system by infection, which favors a cold. The cold, wet season is pure stress for the human organism; clammy Weather weakens the body and its defenses. By frequent stays in heated rooms with dry air during these seasons, the mucous membranes are often not sufficiently moistened and therefore pathogens can be repelled less effectively. As a result, viruses and bacteria can enter the body more easily than in "healthy" Weather. While the name of illness "Cold" signales low temperatures, this alone is almost never the cause for it. According to studies, it is said that the cold may indeed favor a cold, however, the actual trigger of a cold is an infection with viruses. But at low temperatures, the body concentrates the blood in its center to lose as little heat as possible. The result is that blood circulation, in particular of the hands, feet and the nasal mucosa, is throttled. A lower blood flow of the nasal mucosa, in turn, causes the presence of fewer immune cells and antibodies in this region. Thus, it is easier for invading viruses (and bacteria) to establish themselves there and multiply. However, colds are not limited to autumn and winter, even though they occur frequently during just these months. Also in other seasons one is apparently not guarded from a cold. It is not surprising, then, that the common cold is the most common infection of all in people. According to statistics, adults are affected by a cold approximately twice or thrice per year on average, and children, up to ten times per year. Although the course of a cold is very individual, the subsequently described course of the disease is typical: Often it all starts with a slight scratching or pain in the throat. Not long after that, hoarseness in, a runny nose follows, and one develops a cough.Headaches are not uncommon, and one often feels tired and exhausted. Fever is rare, an increase in body temperature is more likely. Mostly, the symptoms of a cold are overcome after one to two (albeit uncomfortable) weeks. A visit to the doctor is often not necessary, because if the immune system is in order the body usually deals with a common cold by itself. However, a weakened immune system makes one vulnerable. Unfortunately, the "ordeal" of a cold cannot be shorten with
