It's freezing! Does sticking our nose outside the house make us get the flu right away?Don't store avocado like this: it's dangerous
Cold doesn't make you sick. You tell your grandparents that today - even if the temperatures are below zero and there is snow everywhere - children can safely go out for a walk. Even if everything is white around, you need a scarf, hat and gloves but there in the sky a shy sun has risen, green light for the snowmen. In short, schools are closed almost everywhere, do you want to see that putting our nose outside the house makes us immediately get the flu? Of course not, and science is now certain on this point.
Sore throat and runny nose, colds and respiratory diseases in general are caused by virus and getting cold has little or nothing to do with it. It is in fact convinced that going out in cold temperatures makes you sick, but to date no scientific research has been able to demonstrate that cold air, snow or wind make you fall more easily in a flu state.
Keeping children outdoors even in cold weather will not force them to bed, because to get sick and for an upper respiratory tract infection to develop, it is necessary to have a virus or bacteria (which in the vast majority of times rather it occurs indoors).
How do viruses behave? To survive, they must continually change to “travel” unchallenged in our immune system and infect the body's cells. At that moment, the immune system has time to activate its defenses and stop the spread of the virus.
The symptoms we all know, such as a sore throat or a cough, are the consequence of this battle between the virus and the immune system. What is certain is that nThere is not necessarily a cause-and-effect link between cold and cold and if it is true that the viruses that cause it are more widespread in the cold season, it is also true that this is the time of year when we are most indoors, sharing confined spaces with several people. It is rather in this context that viruses have multiple ways to spread by air and infect.
Not only that, but the heating in homes it makes the air even drier, which reduces the hydration of the mucous membranes of the nose, one of the barriers that help us keep viruses under control, and thus makes it easier for viruses to spread, which do not find particles of water to bind to.
On the other hand, it is good to remember that the cold - in extreme cases - can be dangerous, if for example you remain outside for a long time without sufficient protection. In those cases, too low a temperature can cause freezing of the hands, feet and, in more serious circumstances, other parts of the body. Catching excessively cold can also cause hypothermia if the body temperature drops below 35 ° C, resulting in frostbite and cardiac arrest.
This is not the case in most of our cities these days, but remember that a little extra cold shouldn't hold you back if you cover yourself and your puppies well!
