Exercise can cut the duration of a cold in half and reduce the intensity  of the awful symptoms. Exercise causes a temporary rise in immune  system cells circulating around the body and this little surge may be  enough to reduce overall upper respiratory tract infection by the common  cold bug and decrease the stuffy nose, sore throat and overall misery  of having a cold.
