In childhood we are limited by many pleasures with one purpose not to catch a cold, in old age we are locked in rooms not to catch a cold, our whole life passes in constant fear of drafts, moisture, coldness not to catch a cold, and yet we catch a few colds every year times. The common cold is probably the most commonly used medical term among the people and despite this it is not clear to people whether the common cold is just a symptom of the disease or is its name. There are not as many different interpretations and misconceptions about any medical term as about the common cold. The cause dates back to the distant past, to a time when nothing was yet known about the causes of disease, while diseases were explained by a bad sign, poisonous vapors from the earth, causes, and divine punishment. Some diseases were explained by the sudden effect of cold on the body, which led to the use of the terms colds, flu, colds, etc. In many areas, these beliefs have persisted to this day. Today, a doctor calls a specific disease, a type of upper respiratory tract infection, a cold. In many languages, the word coldness, chillines, has become a common name for this type of infection.

Even before the First World War, it was proven that the cause of such inflammation was a virus, and this has been confirmed by numerous experiments. Dozens of different types of viruses are known, all commonly referred to as rhinoviruses. Therefore, a doctor by diagnosing a cold understands exclusively a virus-induced infection that affects the upper respiratory tract, most commonly the mucous membranes of the nose and throat. The connection between cold and cold has also been studied and it has been experimentally proven that this connection exists. Sudden exposure of the body to cold causes reflex compression of blood vessels in the nasal mucosa and pharynx, which can lead to a drop in temperature in the nasal mucosa by several degrees Celsius. This significantly reduces resistance and in the presence of rhinovirus infection occurs much more easily than in conditions when the body has not been exposed to cold. It is understandable that there is no cold without rhinovirus. People who live in isolation in the polar regions, constantly exposed to low temperatures, do not suffer from colds. When isolation is broken and they come in contact with people who suffer from a cold or germ carrier, the disease occurs.

It is believed that on average, every person gets a cold at least twice a year. Because rhinoviruses do not create long-term resistance (immunity) in the body, they can get sick several times a year. The disease occurs abruptly, with a feeling of fullness and mild sore throat. Soon there is sneezing and a characteristic discharge from the nose which is initially watery, only to later become mucous or mucopurulent. The eyes become red, breathing through the nose is difficult, sometimes due to the strong swelling of the nasal mucosa. Due to the loss of sense of smell and taste, appetite is reduced. Due to inflammation of the Eustachian tube, the canal that connects the pharynx to the middle ear, hearing is impaired. General disorders of the organism are not more pronounced. Fatigue, drowsiness, headache, limb pain may occur. The illness usually lasts for a week. In rare cases, in people with significantly reduced resistance, the inflammation can affect the deeper parts of the airways. The disease is not highly contagious. Only 20% of volunteers, who are intentionally infected, develop the disease, and under natural conditions the percentage is much lower. That is why the common cold does not occur in the form of large epidemics like some other viral diseases (flu).

The common cold is considered a droplet infection, ie rhinoviruses are expelled by coughing and sneezing and thus spread from a sick to a healthy person. Recent research has shown that about 40% of people who suffer from colds have the virus on their fingers, where they can remain unharmed for as long as a few hours. This means that we can also classify the common cold as a disease of "dirty hands". The spread of the disease can be reduced so that a person suffering from a cold does not move indoors with many people. It is important that the sick person does not shake hands, that he washes his hands often, that he uses disposable paper handkerchiefs, and not pocket handkerchiefs that are just loaded with viruses and represent a real breeding ground for the disease. Most cold patients do not seek medical help but treat themselves, each with their own long-tried method. Some sweat with linden tea, others prefer marshmallow or rosehip tea, a third use a drop of iodine in a glass of water, a quarter are helped by homemade brandy.

It is important to know that there is no possibility of causal treatment, ie there is currently no cure for viruses in the body. There is a so-called symptomatic treatment which means that medications are given that eliminate only the individual symptoms, usually those that are most pronounced. One of the most commonly used medications are nasal drops, which people buy themselves in pharmacies. They work by constricting the blood vessels in the nasal mucosa and temporarily reducing swelling and discharge. Many people use such agents too often and uncontrollably, which worsens the condition, and leads to even stronger swelling and damage to the mucous membrane.

There are much better medicines that dilate the blood vessels in the nose and thus allow a greater blood supply, and thus more food and protective substances produced by the body. The beneficial effect of hot tea, chamomile inhalation and the like is based on this. Vitamin C has been widely used in the prevention and treatment of colds since Nobel laureate Linus Pauling published the book "Vitamin C and the Cold". It was a real "boom" for vitamin C producers. There was a real vitamin mania. Although we know that vitamin C deficiency can lead to a number of disorders in the body, research over the past two decades has refuted Pauling’s claims about the great usefulness of this vitamin in treating colds.
It is important to note that antibiotics do not act on rhinoviruses and that the use of antibiotics is not only pointless but also harmful.
