Sinus washes (also known as nasal rinses or nasal lavages) have been used for centuries to alleviate a number of upper respiratory symptoms. A March 2000 study in "The Laryngoscope" indicated that saline nasal rinses have the ability to treat a variety of nasal diseases, including sinus infections, allergic rhinitis (runny nose due to allergies) and upper respiratory tract infections. These rinses remove allergens and mucus from the nose, thus reducing the potential for allergic rhinitis; they also prevent and remove crusted secretions, which may block nasal passages and lead to a sinus infection. In 2008, the "American Journal of Nursing" mentioned an additional bonus of sinus rinses: they may reduce the need for antibiotics in people who are prone to sinus infections.
Saline solution and nasal rinse kits can be purchased at a pharmacy, but it is much more economical to make your own rinse. Basic saline solutions contain water and salt, but you can add a couple of things to make their use more comfortable. Please consult a physician before using a sinus wash.
Water
Tap water has been shown to be effective, although you may want to boil the tap water or use filtered or bottled water for your rinse. The efficacy of the solution is not dependent on the temperature of the water; however, many people find that a warm solution is more comfortable.
Salt
The use of non-iodized salt (pickling, kosher or sea salt) is recommended as it prevents excess burning during the rinsing process. Table salt will do, but it can sting.
Baking soda
Baking soda prevents burning and soothes irritated membranes.
Glycerine
Glycerine moisturizes the nasal passages and further soothes irritated membranes.
