News JVTech Science has just discovered how we catch colds
A recent study has just proven many doctors wrong who saw no physical connection between colds and getting sick with reduced immunity. Apart from external causes, “getting a cold” was only an expression.
A less preconceived idea about the cold
published on 5 December just showed that the body’s natural immunity could decrease with lower temperatures. Once confined to the phrase “getting a cold”, there seems to be a great deal of truth in it.
This would be an antiviral mechanism that would become less effective as the temperature drops. This study thus contradicts many years of belief that only external causes explain the peak of disease in the winter months.
Previously, the two viral risk factors were that with the cold we are much more in closed places, that we ventilate much less. As a result, we create a pool of bacteria and viruses that spread much more easily. The other factor is that many viruses are more resistant to cold.
Yes, it looks like we are “catching a cold”
In the study, the researchers sampled human nasal mucosa tissue. By taking 5mm by 5mm pieces and then putting them in culture, they were able to experiment with them. By immersing them in a solution for 24 hours at 37°C and 32°C, the results were very different. In one case, the immune response was normal, while the response was less at a lower temperature.
Thus, we learn that when the nose is exposed to a virus or bacteria, microballs that could be described as soldiers protect the air intake. It is for this reason that it is recommended to inhale through the nose and not through the mouth.
This discovery is thus complementary to the previous two in explaining the resurgence of the disease in winter. In the future, we will thus be able to rely on these three factors to explain the development of an epidemic.
This will thus help to better handle the epidemiological crises that we experience every year during the winter period.
