For several years now I've been using a sinus rinse to irrigate my nose. It's a great way to beat back those allergy symptoms and a necessity when we play in smoky bars. If I don't do a rinse after a gig, I'll have a 'bar headache' for a day or two.
The premise is simple: cleaner sinuses, especially before bedtime, are happier sinuses. Additionally, any nasal sprays or other medications are going to work better in a clean nose.
If you haven't done it before, do some research and try it for yourself, I use the NeilMed Sinus rinse bottle and when I ran out of the premixed packets I started using the equivalent home-made version. If you use tap water, be sure to boil it first and cool, as sinus infections are possible and a few deaths have been caused from infection by Naegleria fowleri from using contaminated water. Here are some great reasons to try it and tips for rinsing.
The best temperature is lukewarm, as overly-warm water can swell the sinuses and cold water can be very uncomfortable. Below are a couple of videos that show how fast and easy it is to do.
Sinus Rinse Solution
