Hearing aids, a crucial lifeline for many, often come with a hefty price tag ranging from a few thousand to tens of thousands of dollars. When we invest in these devices, we naturally hope for them to function efficiently and last a long time.

However, being sophisticated electronic devices in constant contact with the skin for extended periods, hearing aids are prone to premature damage from sweat and moisture. This is particularly overlooked during the winter months.

Are you aware of the moisture factors that could affect the lifespan of your hearing aids?

Our skin regulates body temperature by releasing moisture (sweat). Given that hearing aids often come into contact with the skin for several hours, exposure to sweat is inevitable. This becomes more pronounced after physical activities or when the body is under stress.

While many hearing aid brands claim to be waterproof to a certain extent, airborne water vapor can still penetrate traditional waterproof barriers, making your hearing aids susceptible to environmental conditions. In colder weather, entering a warm indoor environment with your glasses might cause them to fog up due to rapid temperature changes. The same can happen to your hearing aids, forming a layer of moisture.

Rain has always been a threat to hearing aids.

Without proper drying, hearing aids won't immediately malfunction. Instead, corrosion accumulates over time, leading to eventual malfunction and premature 'retirement.'

Look out for these signs that your hearing aids might be on the verge of failure:

  1. Static or popping sounds - Corrosion in electrical connections causes short circuits, generating unwanted static in your ears.
  2. Distorted sound or reduced volume - Damage to connection points affects the stability of the hearing aid's audio output.
  3. Intermittent operation - Frequent shutdowns and restarts indicate approaching failure.

Can you wear hearing aids in winter weather?

While traditional hearing aids may be waterproof, they are not immune to corrosive elements like rain or snow. Hence, precautions should be taken to avoid direct exposure to these conditions.

If your hearing aids briefly encounter light rain, such as when closing an umbrella and entering a car, there's no need to worry excessively. Simply remove and dry them as soon as possible. If you won't be using your hearing aids for several hours (such as before bedtime), it's advisable to dry them.

Benefits of Drying Your Hearing Aids:

  • Improved sound quality: Modern hearing aids contain delicate electronic components, and even a small amount of moisture can adversely affect sound quality.
  • Longer-lasting hearing aids: What is the expected lifespan of hearing aids? Most users upgrade their hearing aids every 3-5 years, but their old devices often remain functional. If you want your hearing aids to outlast the manufacturer's warranty period (usually 2-3 years), it's essential to learn and consistently practice hearing aid drying methods.

How to Remove Moisture from Hearing Aids?

Keeping your hearing aids dry is not complicated. Simply place them in a drying container (usually containing drying beads or a drying box) each night before bedtime.

For more thorough drying, consider visiting a hearing aid fitting store for maintenance every 3-6 months. The specific frequency can be determined based on the climate where you live and the humidity level of your ear canals."
