Neti pots are used in yoga practice for jala neti, nasal washing. This can help keep the airways clear and prevent chronic catarrh and rhinitis. Using a neti pot (Google it) or small sterilized teapot, dissolve 1 tsp salt in 1 pint (600 ml) tepid water. Tilt your head sideways over a sink. Placing the spout of your pot against one nostril, pour the saline solution up your nose. The stream of water should trickle and then pour out of the other nostril. Blow your nose well, then repeat on the other side. If this is uncomfortable or your nose feels sore, reduce the amount of salt.
