Not unusual: The congestion alternates about once every 3 hours but is usually not noticeable in the absence of moderate nasal congestion. You will need to see your doctor if you are bothered by this to find out the cause. Exercise leads to increase in norepinephrine (a stimulant and nasal decongestant) and leads to the decongesting effect.
