In the United States, it is estimated that people have 500 million colds in the course of a year (Fendrick AM et al 2003), averaging three to six colds per person (Rajnik M et al 2005), so they are very common for all.
There is also no evidence that your chances of getting a cold are related to factors such as exercise, diet, or enlarged tonsils or adenoids. On the other hand, research suggests that psychological stress and allergic diseases affecting your nose or throat may have an impact on your chances of getting infected by cold viruses.
Amy, studies have demonstrated that increased stress greatly increases the risk of developing the common cold (Cohen S et al 1998). A number of published studies show that, if zinc lozenges are taken within 24 hours of the onset of common cold symptoms, the severity and duration of cold miseries are significantly diminished (Hulisz D 2004; Prasad AS et al 2000; Marshall S 1998; Mossad SB et al 1996). Zinc inhibits the ability of viruses to take hold in the body.
