Sea water! A good old, old timers remedy. Get some, go outside, sniff it in and it makes you blow out automatically. Not nice, but do it a couple of times. Clears your head, nostrils etc. You may laugh at me but that's ok. My grandmother made me do it everytime I went to visit her at the sea many years ago. It did me no harm and I was never sick.
