Why is that, that water doesn't enter the ears when we swim?

I think it is because of our ear holes are on a straight position, so the water can not entering our ear. But if you try to turning your head about 90 degree, the water will surely entering one of your ear hole which is the top one. At least we know that our ear surface is not plain so it also helping us to preventing the water entering our ear holes. Have a nice day and happy mylotting.

when we take a bath or shower the water will not go in to the ear, hahaha But how ever when we all go for a swim in a pool , that is different. Yes we do get water in our ears, some time's you can fell it. and it is hard to get out, when you sleep at night , it comes out.

A good question! I think it is because of that, that the ear opening is too small and there is no "exit". Like with a refill- try to put it into water and you will see that no water go in. P.S. Sometimes when I swim the water goes into my ears.

The water can penetrate the ears but it may be in various forms that lead to infections without one's knowledge. Studies have shown that several ear disorders were a product of water penetrating the ears while swimming, bathing or showering. so they suggest to put an ear piece cap protection to prevent the passage of water to the ear and reaches other soft membranes that can lead to infections.

well from my experience it does :) you can't really tell at the time but afterwards when you feel it and hear it moving around in the ears and man its annoying. And when you tilt your head from side to side to try and get it out it doesn't, well, very rarely in my experience. so yeh, it does. Why else would everything sound muffled underwater :P
