There are a lot of people swimming in summer, but one problem that bothers us is that our ears suddenly feel stuffy, blocked and watery after swimming. Don’t panic and don’t be nervous because the outer ear canal is a curved S-shaped blind end that is completely separated from the middle ear by the eardrum. Therefore, when water enters the external ear canal, it is able to flow out on its own. If you feel that there is water in the ear canal and it is stuffy and uncomfortable, you can use the method of jumping on one foot to make it flow out. You can also wipe it slightly with a fine cotton swab to dip the remaining water in the ear to avoid letting unclean or polluted water stay in the external ear canal for too long, which can cause inflammation or infection in the external ear canal and a series of symptoms of pain and pus flow. Therefore, when water enters the external ear canal while swimming, you can first use a single-legged jump to let the water flow out, while probing with a fine cotton swab to wipe out a small amount of residual water to ensure the cleanliness of the external ear canal and prevent inflammation.
