Most uncomplicated colds, which often lead to coughs, last between eight and nine days, but about 25 percent last two weeks, and 5-10 percent last three weeks. How quickly your cold is resolved has a lot to do with your general lifestyle habits and the state of your immune system.
The average duration of cough, according to a recent study, is 18 days. If you think that seems like a long time, youâre not alone. A telephone survey by the same researchers found most people expected a cough to last seven to nine days. That dissonance between how long people expect cough to last and how long it really does sends a lot of people to the doctor.
