Hearing aids are sophisticated electronic devices designed to improve daily communication, but their intricate components are highly susceptible to moisture and humidity. Water exposure is a major threat that can lead to internal damage and failure. This article addresses the vulnerability of hearing aids to water and steam, explaining modern protection standards and outlining best practices for device care.
The Direct Answer: Water and Hearing Aids
The definitive answer is that standard hearing aids should never be worn in the shower. Direct spray can force water into the device’s tiny openings, immediately overwhelming the protective seals and coatings. This direct contact can cause short circuits within the sensitive electronic circuitry, leading to sudden device failure.
Beyond direct water, the high heat and steam generated in a shower create a severe humidity problem. This warm, moisture-laden air can penetrate the casing and condense inside the hearing aid, coating the delicate internal components. This internal moisture can lead to galvanic corrosion, causing metal contacts to rust and degrade over time. Prolonged exposure to shower steam significantly shortens the lifespan of the technology.
Understanding Water Protection Ratings
Modern hearing aids feature Ingress Protection (IP) ratings, a standardized measure of a device’s resistance to foreign objects like dust and liquids. This rating is represented by two numbers following the letters “IP.” The first digit indicates protection against solids (0 to 6), and the second digit indicates protection against water (0 to 8). A common, high-level rating is IP68, which signifies the highest protection against dust and resistance to temporary submersion under defined test conditions.
It is important to recognize the distinction between “water resistant” and truly “waterproof” when considering these ratings. Most high-rated hearing aids are considered highly water resistant, meaning they can safely handle daily exposure to sweat, accidental splashes, or rain. However, even an IP68 rating does not guarantee immunity from the continuous, pressurized water flow and steam of a shower environment. Manufacturers strongly advise against intentional water exposure, as chemical impurities in water can still cause damage.
Best Practices for Shower Safety and Storage
Preventative action is the most effective way to safeguard your hearing aids from water damage associated with showering. Always remove the devices before entering the shower, sauna, or steam room to eliminate the risk of direct exposure to water and excessive humidity. The bathroom is an unsuitable storage location due to the lingering moisture and temperature fluctuations.
When removed, hearing aids should be stored in a cool, dry place, such as a bedroom dresser or nightstand, away from heat and direct sunlight. Incorporating a drying routine is a mandatory step for device longevity, especially after exposure to any high-humidity environment. This involves placing the hearing aids in a specialized drying kit, such as an electronic dehumidifier or a container with desiccant crystals, to draw out accumulated moisture overnight.
If a hearing aid accidentally gets wet, quick action can minimize potential damage. Immediately turn the device off and remove the battery, leaving the battery door open to allow for air circulation. Gently shake the device to dislodge any trapped water droplets, then wipe the exterior thoroughly with a soft, lint-free cloth. Never attempt to use a hairdryer, oven, or microwave, as excessive heat will melt or warp the delicate plastic and internal components. Afterward, place the device in its drying kit for an extended period before attempting to use it.
