You might consider flushing your sinuses. A netti pot is best for this, though some people make do with other devices. It is designed to permit you to pour a salt-water solution into one nostril and have the solution wash through your nose, exiting through the other nostril. It takes a bit of practice to learn to relax enough to let the water flow, but I find that it really helps me avoid allergic reactions and recover from the onset of a cold.
