Moisture and Hearing Aids: Why Protection Matters

Hearing aids are powerful pieces of technology designed to improve your quality of life—but like most electronics, they don’t mix well with moisture. Whether it’s sweat, humidity, rain, or accidental water exposure, moisture is one of the most common causes of hearing aid damage. Understanding how moisture affects your devices and how to protect them can help extend their life and keep them working their best. Moisture can seep into tiny openings in your hearing aids and cause internal components to corrode or malfunction. 

Over time, this can lead to:

  • Distorted or weak sound

  • Intermittent function or complete failure

  • Shortened battery life

  • Costly repairs or replacements

Note: Even small amounts of moisture—like perspiration during exercise or humid summer air—can build up and cause problems if not addressed.

Most Common Sources:

Many people are surprised by how often their hearing aids are exposed to moisture. Common sources include:

  • Sweat from daily activities or workouts

  • High humidity or hot weather

  • Rain or snow

  • Accidental splashes from sinks or showers

  • Condensation from moving between cold and warm environments

Tips: 

  • Remove hearing aids before showering or swimming. Even “water-resistant” devices are not meant for full submersion.

  • Dry them nightly. Use a hearing aid dehumidifier or drying kit to remove built-up moisture. 

  • Wipe them down daily. Gently clean your hearing aids with a dry, soft cloth before storing them.

  • Store them properly. Keep devices in a cool, dry place when not in use—never in the bathroom.

  • Open battery doors or power off rechargeable devices at night to allow air circulation (if applicable).

If you notice changes in sound quality, crackling, or your hearing aids stop working after possible moisture exposure, don’t wait. A hearing care professional can inspect, clean, and dry your devices properly—often preventing more serious damage.
