when changing seasons

The weather is changing, you remove warm clothes from the wardrobe, adjust the room temperature, taking fashion season means for the prevention of which everything they say, and suddenly ... ill. Why does the new season brings a cough and runny nose with him? The answer is quite simple: viruses like cold weather.

Seasonal disease

It may seem that the same virus "decimated" we have every time the weather changes, but in fact the culprit cough varies throughout the year. When winter gives way to spring, and when autumn replaces summer, cold viruses thrive. The two main viruses that cause SARS - a rhinovirus and coronavirus, they actively proliferate in cool weather, which is characteristic of the off-season.

However, you are in the winter, is likely to have been infected with influenza. The influenza virus multiplies and spreads most efficiently when the air is cold and dry. Scientists have discovered that at temperatures slightly above zero in the virus appears gelatinous protective outer coating, which helps it to withstand the effects of natural factors. This coating starts to degrade at about 22 degrees celsius. This makes sense, since the coating must "melt" in your body, so that the virus was released and infect healthy cells, but it also means that the virus is less protected in the open air when the weather gets warmer. Ill with the flu or a cold, you develop some immunity to the virus that causes the disease. As a rule, you become immune to it for the remainder of the season. If only it did not fly around you are other strains of influenza and colds.

Why do we get sick when spring comes summer change? This is completely different. New types of pollen and other allergens, which fill the air with the onset of summer, can cause nasal congestion and other problems. Which in turn can lead to disease, as irritated lungs and nasal passages are more susceptible to infection.

Say seasonal diseases - NO!

As to whether in itself cold weather cause colds, it's a myth. The disease causes the specific conditions associated with cold weather - dry air irritate your mucous membranes, and the fact that we spend more time indoors, in contact with people who are sick themselves and infect us. To protect yourself, do not forget to wash their hands regularly, to give enough time to sleep and exercise, as well as a flu shot every year.
