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. 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.
