"Shooting Saltwater Up Your Nose
Is your nose stuffed up enough that diving isn't appealing, or even to the point where congestion may dangerously interfere with equalization of the ears?
It may sound a bit zany and gross, but the evidence, both published and anecdotal, largely supports the salubrious effects of saline irrigation on both nasal membrane drying and congestion (e.g., from long airplane flights, breathing hyper-dry scuba gasses and allergens). Such irrigation shrinks the mucus blanket and flushes out the excess, reducing nasal irritation and swelling.
There are scores of salt-based OTC nasal washes on the market such as Sinucleanse, BreathEase and an array of
NeilMed Pharmaceuticals, Makers of Sinus Rinse, NasaFlo Netipot, Nasal Irrigation products. Many come with a soft syringe. Or you can purchase special tips that attach to oral hygiene devices (e.g., the WaterPik NA-2Gentle Sinus Rinse).
Many divers choose a simple home remedy that is cheaper and works just as well. Boil two cups of tap water for 10 minutes, stir in one teaspoon of salt (refined sea salt is recommended to avoid additives) and one-quarter teaspoon of baking soda (sodium bicarbonate). Adding more salt than recommended can do more harm than good, so don't overdo it.
After the brew has cooled to lukewarm, draw it into a clean nasal or ear syringe until full, then lean over the sink, squeeze gently and allow the solution to run through the nasal passages. Alternatively, one can use a
Neti pot - Wikipedia, the free encyclopedia. When the liquid has drained, sniff in, spit out, then gently blow your nose. Repeat with the second nostril. Again, don't overdo it - - one or two treatments a day should be sufficient. And go make your next dive. - - Doc Vikingo”
