Dog jumping into water to demonstrate how hearing aids can get wet easily when you're having fun this summer because moisture damages hearing aids.

There are many factors which can affect the circuitry of your hearing aids. In fact, you could call moisture kryptonite for hearing aids. Even if you already know that and take care to protect your investment from the shower, pool, or a good face washing, chances are you are missing the most common reason for water damage in hearing aids: humidity.

Invisible moisture has the highest chance of causing irreparable damage. It’s time to understand more about why humidity is a damaging thing for hearing aids.

What is Humidity?

Even though the word humidity is very common, what does it actually mean? PBS describes humidity as water molecules in the air. The relative humidity refers to the ratio of water molecules in the air compared to how many the air can actually hold. When you can feel wetness in the air, that means the relative humidity is high.

Humans cool down their body by sweating so that makes us very sensitive to humidity. When humidity levels are too high our sweat won’t evaporate as fast. Electronics are also susceptible to humidity and that is why it has such a detrimental effect on hearing aids.

Typically Electronic Devices Have a Hard Time Coping With Humidity

Too high or, too low, humidity can influence your hearing aids. When water vapor percentages are high condensation can accumulate on the delicate elements that make electronic devices work, and low humidity can result in brittle core materials.

Hearing aids rely heavily on internal electronics to work. Newer digital hearing aids use a state-of-the-art audio processing chip to control noise. It’s what is behind elegant functions like:

  • Noise reduction
  • Anti-feedback
  • Targeted listening programs
  • Digital sound streaming

High humidity causes moisture to accumulate in the hearing aids destroying that chip. It can corrode elements inside the casing and destroy batteries also. It’s the equivalent of throwing your hearing aid in a sink of water.

Dealing With Humidity

Water resistant models are currently available. Having this feature doesn’t mean you can swim with your hearing aids in your ear, but it does offer some protection from humidity and other weather-related issues like getting caught in an unforeseen rainstorm or even sweat when you exercise.

When it’s very humid try to lessen indoor water vapor by using a dehumidifier. It’s not only your hearing aid that will benefit, there are health benefits, and other electronics in the home will also be protected. Dehumidifiers reduce the risk of mold, mildew and dust mites, so everyone breathes a little better, too. Although a house or room dehumidifier will help protect your hearing aids, it’s not enough. There are a few other things you can and should do.

Look for the dehumidifier made for hearing aids. They come at all costs levels. Drying kits rely on silica gel crystals to protect the electronics. Moisture is eliminated by putting the hearing aids into the dehumidifier for a couple of hours. There are also storage containers that dry hearing aids out each night as you sleep. If it is very humid and you have no other way, uncooked rice can reduce moisture.

Get in the habit of opening the battery compartment every time you store your hearing aids. When you expose the battery and inner elements to air by leaving the door open, condensation can evaporate by itself. Don’t just do this in the summer, do it all year round.

Always store your hearing aids in a cool, dry place. Avoid putting them in the glove compartment, in a hot room or on a table in the sun.

Thinking Past Humidity

Air vapor is not the only moisture that can damage hearing aids. Don’t forget to think about other types of wetness like:

  • Make sure all lotion or sunscreen is fully absorbed before touching your hearing aids or putting them in your ears.
  • Leave your hearing aids in a safe place before you go swimming.
  • Wear a sweatband when exercising. It’s a good practice whether you wear your hearing aids when you workout or not. Sweat in your ears can cause problems later.
  • Try not to put your hearing aid down on wet surfaces. A glass or coffee cup can leave moisture behind.

Your hearing aids are a valuable asset, so treat them that way. Consider how moisture and humidity can impact them and take steps to prevent water damage. If your hearing aid already has water damage make an appointment for service with a hearing aid specialist.
