In conclusion, the importance of ear hygiene for swimmers cannot be overstated. Swimming in pools, lakes, and other bodies of water can cause water to enter the ear canal, leading to ear infections, earwax build-up, and swimmer’s ear. To prevent these problems, it is important to maintain good ear hygiene by using earplugs, drying the ears thoroughly after swimming, avoiding swimming in dirty or contaminated water, and getting regular ear cleaning by a professional. Microsuction is a safe and effective method of ear cleaning and it’s highly recommended for swimmers as it can effectively remove earwax and prevent complications caused by water entering the ear canal.
