My wonderful physician told me to take 2 cups of warm water, add 1/2 plus 1/8 tsp (measuring type, not kitchen teaspoons) salt (plain old table salt), stir well; then take 1 kitchen tablespoon of the saline solution, put one nostril completely into the water and sniff it up into the nostril. Repeat on the other side. Grab a paper towel and blow out the, uh… ‘results’. No burn, no sting and does NOT make you feel like you’re drowning.
Great way to wash out pollen grains which cause allergic responses, various offending organisms (unless they’ve already entered the cells), and clear the openings into which the eustachian tube drains. Can be used as often as you like. Just keep the container covered so the water doesn’t evaporate and leave too much salt in the solution. Put it in the microwave, nuke it for 30 seconds and you’re ready to go again. Change it out every day.
Also, a great way to be able to sleep at night with your mouth closed.
