Sarcastically speaking, the best way to prevent swimmer’s ear is to stay out of the water. But sometimes it is impossible to avoid such a scenario. In the event that you submerge yourself in water, make sure you use cotton swabs to lower the chance of infection—handle cotton swabs gently. Also, after taking a dip, make sure you dry your ears lest you tremble with pain later. The use of acetic acid can also be applied to your ear drum after swimming to prevent the spread of fungi and bacteria.
