Many people don't understand how something as simple and inexpensive as jala neti can be effective. To figure out how it works, scientists have done some research. Their findings scientifically support the use of jala neti as an effective healing measure. Jala neti mechanically flushes out bacteria, viruses, dust, and allergens. Jala neti thins the remaining mucus so that sinuses and their ostia (openings) don’t clog leading to pressure and infection. Jala neti decreases swelling of the nasal mucosa for less stuffiness. Jala neti removes histamine, leukotrienes, and other naturally occurring chemical substances that provoke inflammation and discomfort. Regular practice of jala neti increases the frequency that cilia beat to remove mucus, crusty deposits of snot, and dusty debris. Cilia are tiny little hair-like structures that beat back and forth like windshield wipers clearing a windshield.
