I have a friend that blows both nostrils at once and never fails to make a very loud trumpet noise. Even way back in 4th grade she never failed to interrupt a class when she blew her nose and kids would laugh.
Ummm...honestly I have no clue...I havent really paid that much attention to how I blow my nose....LOL...I have a hard time, paying attention to stuff...
Only reason I ask is because I've been really sick, nose is completely red and sore from blowing it, and I was trying to find a method that gets the most out the fastest and with less blows to make my nose hurt less.
I know this because I had to blow mine today, I give each nostril a turn to do their very best. Why make them compete against each other and lose force? It'll make your ears pop anyway, and I hate it when my ears pop!
it depends on the level of buggers i feel i have in there.
if i feel like i have a ton i will do one nostril at a time and give it a long steady medium blow.
if its just a little stuffy, i will give both of them at the same time a light blow.
