To avoid developing Sinusitis during a cold or allergy attack you should try to do the following:

	Try to avoid air travel
	Remove pets from your home
	During the summer months, if you swim, keep your head above water and avoid deep dives and somersaults.
	Avoid temperature extremes
	Drinking plenty of fluids as this will keep nasal discharge thin.
	If you smoke, try to quit
	Gently blow your nose- by blocking one nostril while blowing through the other
	Keeping the air humid at home
	Drinking less or no alcohol
