With a cold, the mucus of the nose thickens. This impairs the nasal cilia movement that is needed for health. With irrigation, the thick mucus is removed and is replaced by thin saline. This allows the cilia to move again to defend the body. Pulsation moves the cilia back and forth, which helps restore normal movement of the cilia.
Warm saline encourages blood flow to the sinus and nasal passage linings.
Anyone can irrigate their own sinuses. With the Water Pik and the Grossan Sinus Irrigation Tip you don't need any special training. All you need to do is to mix a teaspoon of salt in water, add it to the Water Pik , and turn it on. You will then have a shortcut to your Allergy Superstore's Web Site. 2001 - Allergy Store.
