Answer: Myth
"No, being out in the cold or being cold or having wet clothes does not increase your chance of having a cold or the flu," said Dr. Jon Abramson, chairman of the department of pediatrics at Wake Forest University Baptist Medical Center.
"This is one of the myths that do exist both about the common cold or the flu, and clearly from a lot of studies this is not the case."
Since this myth persists, the likely reason behind it is the rise in cases once the temperature drops in the United States.
"It is true, however, [that] the flu virus circulates mainly in the fall and the wintertime, and that therefore, you do see a lot more flu during that time than the rest of the year in temperate countries, such as the United States," said Abramson.
While the viruses are more common during these times of the year, the consensus among physicians seems to be that this is caused by people staying indoors to avoid the cold -- not from the cold itself.
