    Question about water in the nose

    Hi, I just registered. I live in EU, but I just wanted to ask some pro's about this.

    So, I tried swimming underwater dolphin kick on my back today and it went quite well after a few tries, after I had gotten used to having water up in the nose.

    My question though is if this can be applied to diving as well. The local swimming pools deepest basin is 13 feet deep and I can almost dive to the very bottom of the pool by holding my nose and trying to equalize the pressure (needs some more work though, it's as if water is getting through my ears or something). So, when I'm used to having water up in the nose, can I just fill my entire head with water for an equal amount of pressure on it, or would the breath-holding-thing in the throat give up because of the pressure and I'll drown?

    I'm asking because I'd rather not have to wear a diving mask, just goggles, but if that's the way I have to go, I guess there's no way around it.

    I'm not going to do any freediving, just random diving to 30 feet or so (for dolphins in the future, I'm training hard)

    You cannot equalize the air pressure in swim googles like you can in a scuba mask. If you dive too deep you may get some "raccoon eyes" from the pressure. If you go deeper you may cause some blood vessels to rupture giving you red, bloodshot eyes. I don't think 13 feet wil be too bad but 30 feet my not feel too good. Buy or borrow a scuba mask if you can. You can let air out of your nose to equalize the pressure in the mask.

    Not sure you'd drown, but you wouldn't be happy. The short answer is, no, you can't do that.

    Hmm, I never thought about that. I can see your logic. I guess I do have to wear a scuba mask afterall then. It just looks so stupid. And it probably restricts streamlining a lot.

    I thought so. I just wanted to make sure, cause it was kind of a random idea that got into my head. Imagine if I actually tried it lol.

    Re: Question about water in the nose

    Filling your sinus cavity with water will do little to relieve ear barotraumas (the discomfort and possible damage in the ear due to pressure differences between the middle and outer ear), since it is the air in the middle ear and not the air in the sinus cavity that needs to be equalized. And flooding your sinus cavity may actually make it harder to equalize pressure by creating a blockage to the eustachian tubes.

    At 30 feet you are around 2 atmospheres of pressure, so unequalized air in your goggles will be at their surface volume. For most people this might be painful, but you are at low risk of sucking your eyes out of your head.

    Sounds like I might as well get that Scuba diving mask instead of risking my healthy well being.

    Just to be clear, you CAN equalize the pressure in your sinus cavity while wearing goggles.. Typically you hold your nose to do that with or with out a mask. You CANNOT equalize the pressure around your eyes in your goggles.

    And a good pair of fins is also a good investment.

    Yeah, I was thinking of buying a lunocet or a some monofins like SOMMAP's. I don't know all of the available market regarding these kind of fins, but I think those I found there seems to perform quite well - or so I've read.

    Those lunocet fins look cool. I had a pair of SIDI shoes last 15 years

    This just sounds incredibly painful! Have you met with an instructor or anything that can help you train a little better? Swimming with the dolphins sounds like a great goal, but it might be best if you talk face to face with a professional before you actually try it.

    Re: Question about water in the nose

    What sounds painfull? Having water in the sinus or using goggles at deep depths?
    I haven't done either, hence the reason I asked here. However, swimming on the back underwater takes only a few tries before you're fully used to having water in the nose. Now I can do a flip turn without having to blow air out of my nose. It's incredibly helpful training.

    Re: Question about water in the nose

    I've got another question just now.
    If you use earplugs of some sort that really seals off the ear, do you need to equalize pressure when diving? How much will the ability to hear be reduced? Can you even hear at all underwater with earplugs?
    If the above is true, how deep can you dive before the pressure gets so big that the earplugs themselves are getting an issue?

    Re: Question about water in the nose

    OK ____ 2 different water related sports need different equipment.goggles for swimming near the surface. If you want to go deeper a good mask with a nose area that you can pinch to relive pressure & [ I suggest] a dump valve to remove water that might get into the mask.

    Re: Question about water in the nose

    Yeah, I know that already. If you look at the dates you'll see when my initial question was asked.
    I just extended the diving question a bit because I wanted to know about the safety of my ears.

    But I have to ask an additional question now; How does a dump valve work in a diving mask? You have to make more pressure on the inside than the outside of the mask for the water to get away right? If so, how deep can you dive before it's impossible, as in, how much air pressure can one generate with their lungs?

    They're gorgeous but having cycling shoes (or any shoes) in the water seems like a real drag...
