You’re probably aware of the devastation that can result due to water damage in hearing aids. A few moments in the rain or an accidental spill into the sink will leave many people frantically toweling off their expensive devices or forced to purchase a replacement years before they had planned. Unfortunately, liquids are just one form of moisture that can ruin a hearing aid—and daily wear may produce a larger threat than a downpour.
Hot Weather Increases the Risk of Moisture Buildup in Your Device
Most water damage is caused by condensation, the buildup of moisture inside a hearing aid that coats the tubing and case. While the location of the device next to a warm ear canal generates a lot of this moisture, the heat of the summer sun only increases the danger of condensation and corrosion due to:
- Sweat. People sweat more often and more profusely in higher temperatures, but they also produce more ear wax and facial oils. All of these can damage a hearing aid by blocking the filters and tubing, breaking the receiver or microphone, and corroding the battery contact points. Sweatbands provide some relief by wicking sweat down and away from the ears, while nylon sleeves that wrap around the device protect the hearing aid from moisture (as well as dirt and debris).
- Sprays. Patients in the Southwest may always have a can of bug repellant handy, but in the summer months they may have to add a few extra layers of spray-on protection. Sunscreen to prevent burns and hair spray to keep an updo from falling flat can all clog a hearing aid’s microphone ports, so users should always remove their devices before applying any lotions or sprays.
- Swim. A dip in the pool may be the only way to get relief from the heat, but your hearing aids aren’t safe near the water or in the sunlight. If you take your hearing aids to the pool, remove them before swimming and keep them stored safely in a waterproof container in a cool, shady spot.
One of the best ways to remove moisture build up is to store your device in a dehumidifier or a dry-aid kit overnight, allowing the condensation to evaporate before you put them on in the morning. If you do not have a dehumidifier, storing your hearing aids in a bag of uncooked rice can also prevent corrosion.
