When we have a cold, we have the flu - we are wrongly afraid of coughing. Meanwhile, "coughing" cleanses the respiratory tract of germs. Cough reflex is more effective when it is supported by a syrup, which is often bought without a prescription.
There is no cough in the cold
Cold symptoms are: frequent sneezing, watery nosebleeds, nasal congestion, sore throat, subfebrile (most often body temperature does not exceed 38 degrees Celsius) and ... sometimes cough. The common cold usually infects only some of the airways - for example, nose or throat. Therefore, in contrast to the flu, cold mucositis does not irritate too many cough receptors and is distinguished by the initial lack of cough.
When the flu develops ...
When the body is weakened - inflammatory viral infection easily spreads to the larynx, paranasal sinuses, the trachea and the bronchi. Complications of colds already irritate numerous points cough receptors and cause tiring dry - so-called. ineffective cough.
Flu symptoms
Influenza viruses intensely penetrate the epithelium of the nose and throat. They multiply rapidly in the ciliary cells of the respiratory system causing their necrosis. It exposes the mucous membrane from physiological shields and facilitates the massive invasion of pathogenic germs. Influenza viruses produce specific venoms (pyrogens) that irritate the thermal centers of the brain and increase body temperature rapidly. High temperature - above 39 degrees - can last for 4-5 days. In addition, flu is accompanied by: bone and joint pain, muscle pain, weakness, general breakdown, runny nose, cough, conjunctivitis, less abdominal pain, vomiting. A cough?
Cough in flu
The cough in flu appears at the beginning of the disease. Rapidly multiplying viruses destroy the respiratory tract mucosa and cause it to swell and redden (inflammation). The irritations are so-called coughing points and induces a dry, non-productive cough. Influenza viruses destroy the goblet cells of the mucous membrane, impairing the secretion of a mucus that facilitates the phlegm formation. The resulting deposits of thick, sticky phlegm full of germs irritate unsuccessfully the cough receptors of the nose, throat and trachea. An intense dry cough is therefore unproductive and does not bring cleansing of the airways. It has a paroxysmal character - tiring and debilitating the patient.
Bronchial cough
The bronchial mucosa (and trachea) has a special mucociliary mechanism of self-cleaning of contaminants and germs. Mucus, popularly called phlegm, is "pushed out" by millions of waving microscopic cilia. When the viral infection reaches the bronchi and destroys the goblet cells, the mucus becomes dehydrated, thickens and immobilizes the ciliary mechanism of self-cleaning of the airways. However, the laxative phlegm irritates cough receptors and causes a coughing reflex that should "throw away" the mucus from the outside. Often, however, the cough is "dry", i.e. useless. Stable thick, sticky phlegm is too dehydrated to be removed without the use of appropriate cough syrups.
When a tiring dry cough dies - we use expectorants
The most important in the early phase of cold disease is the effective removal of dense mucus secretions residing in the airways. This is done by two methods - by stimulating cough points (cough center) and by increasing the amount of mucus secreted and decreasing its viscosity.
Effective treatment with cough syrup
WHEN KASZEL IS "DRY" AND COMES TO VIRAL INFECTION THROUGH BATTLE - effective treatment is based on the dilution of mucus (phlegm).To this end syrups are stimulated by mucous glands, which "hydrate" phlegm. Thinning of mucus slimes releases millions of microscopic cilia of the airway epithelium stagnated in them and triggers their physiological "waving", which pushes the mucus and contained germs and pollutants out. Most importantly - liquefied phlegm can be abundantly and easily formulated during the expulsion.
In many expectorant syrups, guaiacol stimulates expectoration of phlegm
Guaiacol - a natural plant substance obtained from beech wood. Processed into a medicinal product - e.g. guaifenesin - after oral administration stimulates the stomach mucosa to increase the secretion of the bronchial glands. After absorption, it undergoes a partial displacement to the bronchitis and here, irritating the mucous membrane, stimulates the bronchial glands to produce additional portions of rare mucus. Due to the dilution of the mucus, the cough becomes "wet", cleansing the airways - in a word "productive".
