Saline Moisturizing Nasal Spray
No matter how careful you are or how many masks you have on... You are going to breath in playa dust. It may help to wash it out sometimes. In addition, it's hot and dry. Your nose will take a beating just breathing in that air. I like this spray because it has the extra moisturizing ingredient, which does help.
This year at Burningman, I laughed, I cried, and I craved saline nasal spray. The playa boogers are far from fun - and who wants to breathe in all that playa dust anyways? Saline nasal spray is an absolute MUST HAVE. Buy ten, and give them out to your friends (old or new). They'll thank you.
