Sutra Neti is a yogic nasal cleansing technique that involves threading a rubber catheter or string through the nasal passages to clean and maintain their health. This practice aims to clear mucus, debris, and pollutants from the nostrils, promoting better breathing and sinus health. Sutra Neti is beneficial for individuals with sinus issues, allergies, or nasal congestion. It is considered a part of the Shatkarma practices in yoga, which are purifying techniques to support overall well-being.
