Water in your Nose Problems?
Everyone who has ever gone swimming has at some point experienced the exquisite pain of getting water up their nose. When you jump in the water without plugging your nose, it feels like it goes shooting straight up into your brain. Of course, water that gets up your nose doesn’t actually go into your brain. It just hits your sensitive sinus passages. But it still hurts.
The reason water gets up your nose is because of a difference in pressure between your sinuses and the water around. Your sinuses are filled with air like a balloon. If the pressure in your sinuses is kept constant, there will be no room for water to get in. However, many people jump into the water with their windpipe open straight down to their lungs, which gives plenty of room for the air to be forced downwards and for water to rush up your nose at your cannonball. If you close up your sinus cavity, the air pressure will keep water from getting in through your nostrils.
So how do you close up your sinus cavity and keep the pressure constant? Press your tongue against your soft palate and make the “k” sound. Feel how your nose and mouth are both cut off from your lungs as long as your tongue is holding the “k” position. To blow out of your nose, you have to move your tongue. As long as your tongue is in that spot, your sinus cavity is blocked off and the air pressure will be constant.
