Spending an extended period of time in saline sea water or chlorinated swimming pools makes the skin of the auditory canal swell and may sometimes aid the growth of pathogens. Protecting the ears from the influx of water is important to ensure that the fun in water does not lead to bitter repentance or a painful inflammation of the auditory canal. SANOHRA® swim ear plugs offer ear protection during all types of swimming and water sport activities. Ear plugs are generally unsuitable for diving beyond a depth of 3 feet.
