The common cold is the first thing that comes to mind in the winter season. Outbreaks appear to be exacerbated during early winter, when temperatures drop. In addition, those who have problems with asthma or cough for many days, the cold weather also increases their suffering. Lung pneumonia is also common during this time. In other words, the main cause of the disease in winter is the respiratory system.

Why respiratory diseases increase in winter

Many people think that if you stay cold for a long time or get wet in water, you get cold, you get cold. Although the main cause of these diseases is the virus, it is also related to the outside temperature. Experts believe that the enzymes associated with our body’s immune system become less effective at lower temperatures than normal. As a result, the body’s immune system is weakened. As the air temperature drops in winter, so does the humidity, which disrupts the normal functioning of our airways and facilitates the onset of the virus. Dry weather helps spread the virus in the air. In addition, the amount of dust increases. Cold, dry air narrows the asthma patient’s airways, leading to increased asthma.

Symptoms of cold-cough and influenza

Colds and coughs start with a sore throat, a sore throat, nasal congestion, runny nose and sneezing. Headaches, muscle aches, body aches, weakness and loss of appetite occur gradually. Mild fever and dry cough may also occur. It is a disease of the upper respiratory tract and gets better on its own in 5-10 days. However, in some cases the cough may last for several weeks.

Influenza is mainly a disease of the lungs and in this case fever and cough are very common. In addition to other symptoms of cold, there may be shortness of breath in this case. In addition, the body of the virus is often attacked by bacteria. Especially if the runny nose is very frequent or the cough is accompanied by yellowish phlegm, it indicates an attack of bacteria. In winter, not only the lungs but also the sinuses, ears and tonsils become inflamed.




Every winter, almost everyone is familiar with these symptoms. However, newborns, children, the elderly, asthma patients and smokers are most affected by these diseases.
