As the winter approaches here at state college, I am becoming a bit frightened because I had already had bronchitis twice since I have gotten here, and the peak of the cold weather has not even begun. There is a well-believed and strongly backed fact that people are more likely to get sick in the winter. So there lies a question: what is the cause of this? Is it the weather itself? Through my research on this topic I found that the weather does not directly cause one to get sick. You have to come in contact with a germ or virus to contract a sickness, which is stated here. However there are theories on links between the winter and the likeliness to catch a cold.
Although many of our parents have told us to “come inside, you are going to catch a cold!” That could be a very counterproductive command. There are many possible cofounding variables that could relate the winter with sickness, that have to do with being indoors. For example, this article explains that In the winter, it is not as desirable to spend time outside, therefore people pack themselves indoors and might become more likely to catch something from someone sick in the same vicinity. Also, there are some theories that central heating has a link to a weakening assume system.
On the other hand, our parents could have been right as they were yelling at us from inside the house. There was a study done on animal cells to test these theories. They tested these cells at different temperatures that correlated with the nose and lungs. The results showed that the decreased temperature did indeed decrease the effectiveness of the immunity to fight off the virus. Although this is good first step in testing the hypothesis, the study did not go beyond this, which makes it difficult to know whether this holds true for humans.
It seems as if the link between the cold and a common cold has not been completely figured out yet, but as the season is approaching I wish everyone luck!
