Why smokers are more vulnerable to the common cold? The human nose can fight off viruses, and chemicals from tobacco smoke, but he was not able to do it simultaneously.
Scientists have come closer to understanding why some people are susceptible to coldsand others do not get cold. In the last 10 years a number of studies have shown that exposure to the rhinovirus that causes the conventional cold, does not always lead to characteristic symptoms. Even healthy people are found traces of this virus in the nose. But until recently scientists didn’t understand the reason why someone catches a cold, and someone who avoids the cold, and if it is certainly not related to a weakened immune system.
And now researchers from Yale University found that in our protective armor, a vulnerability that is particularly relevant for smokers, but affected those who are not breathing very fresh air. It turns out that the human nose can not pass into the body of toxic chemicals like smoke or harmful emissions, it is also able to resist the aggressive invasion of viruses. However, the nose is unable to perform these tasks at the same time. In other words, if the nose is protected from tobacco smoke, it transmits viruses. And the first task our body considers a priority.
The study demonstrated the delicate balance between different aspects of the protective mechanisms of our body that allows us to preserve the health or expose it to various diseases. Installed, as this balance is disturbed due to the impact of toxins in products and the environment. Well, for smokers this can be another motivation to abandon a very dangerous habit. (READ MORE)
