There are more and more people who swim regularly as a form of fitness, and some children and teenagers often participate in swimming training, which has great benefits for physical and mental health, but the incidence of swimmer’s ear, as mentioned earlier, has also increased. In the past, some people used non-skimmed cotton or cotton wrapped with soy beans to plug the ear canal eye when swimming to prevent swimmer’s ear, but nowadays it is easy to buy special swimmer’s ear plugs, so there is no need to use that primitive method. However, people often ask, when swimming with swimming ear plugs in the end is not a benefit? Theoretically, it should help prevent otitis externa and otitis media, but there are also factors of personal habits, and the material and design of the earplugs are also very different. Some earplugs are cheap, only a few dollars, but the material is hard and can cause pain after being inserted into the ear, which may damage the ear canal after a long time; some earplugs not only block the sound but also feel a bit stuffy after use; soft and comfortable earplugs may be more expensive. However, for patients who often suffer from swimming otitis media, if they are not willing to give up swimming, they can purchase swimming ear plugs, which we think will have a certain effect on preventing the disease. As for the swimming-specific nasal clip, the number of people using it is even less. The reason for this is that many swimmers have the initiative to exhale underwater and inhale in the water, and the comfort of using the nose clip is not satisfactory enough, and the clip may cause nasal pain after a long time. However, if you practice synchronized swimming or diving, diving, etc., the use of nasal clips can theoretically prevent sinusitis caused by water in the nasal cavity and otitis media caused by choking through the eustachian tube route.
