A neti pot is a small, teapot-shaped device used for nasal irrigation. It helps clear nasal passages by flushing out mucus, allergens, and other debris with a saline solution. This practice can provide relief from sinus congestion, allergies, and colds. To use a neti pot, fill it with a warm saline solution and tilt your head to one side. Pour the solution into one nostril, allowing it to flow through the nasal cavity and exit through the other nostril. This method is often recommended by healthcare professionals for maintaining nasal hygiene and promoting respiratory health.
