One way to relieve common hay fever symptoms is to use nasal irrigation with a neti pot. Jala neti (“water cleansing”) is a yoga technique, commonly practiced in parts of India. It involves pouring warm slightly salted water into one nostril while keeping the head tilted so that the water runs out of the other (lower) nostril Relaxing and breathing through the mouth helps the water run from one side down to the other quickly.
This type of irrigation removes pollen, dust and mucous from the nasal passage. Not only can it improve breathing and post-nasal drip but if used up to 4 times a day prevents common colds or reduces their duration.
