New study, avoid getting sick with the cold

Getting respiratory illness at the best of times is a nuisance, whether it's a mild cold, a flu that's the same as influenza, or that new virus they released; Any of these diseases is something that we would like to avoid, even if it is for convenience, nobody likes to go dripping snot and coughing through life and although you can get sick from these three things at any time of the year, I think we all agree that as soon as it arrives the cold the contagions skyrocket.

Which is to say that there is a connection between cold and our immune ability to protect ourselves from bugs that cause respiratory tract diseases, we know there is a connection, but we didn't know the mechanism by which cold disarms us against viruses. and bacteria so far.

A new study replicated exactly what happens in our noses and the truth is that what happens there is impressive, when a virus or bacteria reach the nose they are immediately detected by the tip of the nose long before the rest of us. the nose finds out, there the cells that line the walls of the inside of our nose detect the intruder by means of receptors in its cell wall and this sets off an alarm signal, which causes the rest of the cells inside our nose to produce billions of tiny copies of themselves called extracellular vesicles.

In a matter of minutes your nose accelerates the production of extracellular vesicles by 160% and prepares an army the size of the entire human population of warriors whose sole mission is to catch and destroy viruses or bacteria that may threaten you and all this happens in the entrance of our nose, they have not even had a chance to enter our body and fight against our immune system.

The snot and the billions of killer extracellular vesicles swimming in it kill the problem before it even starts, these vesicles swimming in your snot trick the viruses that enter your nose into thinking they landed in an ordinary cell where they can start an infection.

But there is such an abundance of extracellular vesicles that viruses end up landing on them and are killed by them, many types of cells in our body are capable of producing small sequences of micro RNA with which they fight invading viruses and bacteria, but extracellular vesicles in the snot from the tip of your nose produce 13 times more microRNA than the rest of your cells, that is, they are armed to the teeth, incredible, now you will see your snot in a different way, they are there for you to fight for your health.

But if your nose, its mucus, and its extracellular vesicles are just as good at fighting off viruses and bacteria, a study by otolaryngologists at Northeastern Boston University found that a drop in temperature of just 5 degrees Celsius is enough to not only inhibit the ability of your cells to detect pathogens by 70% but the production of extracellular vesicles is reduced by 50%.

In other words, a change in temperature as subtle as going out in the cold without a sweater kills half your antiviral army and practically disables your ability to detect the enemy; now what can you do to prevent your first line of defense, your nose and its army from being disabled by the cold, it is very simple wrap up enough so that your nose does not get cold, if you bring a cold nose remember that the army of your nose is off and you are much more likely to catch a cold, flu or the Chinese virus.

Listen to your mom and wrap up.
