“If someone can breathe through at least one nostril, flushing with a mixture of salt, baking soda and warm water can remove pollens and irritants, so they don’t cause further inflammatory reactions,” says Paul Dahlberg, M.D., an allergy specialist with Alina Health in St. Paul, Minnesota. “It’s best to use a squeeze bottle. It’s easier to use than a neti pot, because the latter can cause fluids to run down the throat.”Dahlberg suggests mixing three tsp’s of iodide-free salt and one tsp of baking soda with 8 oz of warm distilled or boiled water, and then squeezing the fluid into one nostril and allowing it to flow out through the other. “Start with the more stuffed nostril, and breathe out as you’re flushing,” Dahlberg says. Skip this trick if you’re stuffed in both nostrils, to avoid a pressure buildup, and make sure the water isn’t cold, to avoid an ‘ice-cream headache.
