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.
A cough that has lasted for between three and eight weeks is termed a âsub-acute cough.â And coughing that has been going on for more than eight weeks is termed a âchronic coughâ.
