Wearing hearing aids while swimming is generally not recommended because most devices are delicate electronic instruments not designed for full water immersion. These devices contain components highly susceptible to moisture damage. While technology offers water-resistant and a few truly waterproof options, standard hearing aids must be removed before entering a pool or body of water. Understanding the specific risks and protective measures is important for preserving the device’s functionality and longevity.
Standard Hearing Aids and Water Risk
Standard hearing aids contain sensitive electronic components that water can easily compromise, leading to two main types of damage. The immediate risk is an electrical short circuit, which occurs when water bridges internal circuitry, causing a malfunction and potentially damaging the processor. This failure often happens if the hearing aid is powered on while wet.
The second risk is chemical damage, which unfolds over time, accelerated by the water’s composition. Pool water contains chlorine and ocean water contains salt, both of which are corrosive agents. These substances attack the device’s metal components, particularly battery contacts and microphone ports. Corrosion can lead to intermittent sound, static, or complete device failure.
Water can also cause physical damage by swelling non-metal parts, such as the tubing in behind-the-ear models. This swelling alters sound quality or reduces the device’s structural integrity. Even small amounts of moisture from humidity, sweat, or rain can accumulate over time, making preventative care necessary for all users. Saltwater and chlorinated water pose a significantly greater threat than fresh water due to their high corrosive potential.
Understanding IP Ratings and Water Resistance
The water protection level of a hearing aid is determined by its Ingress Protection (IP) rating, a standardized two-digit code. The first digit indicates protection against solid particles like dust, and the second digit measures resistance to liquid ingress. A higher second digit signifies greater water protection, with the scale ranging from zero to nine.
Many modern hearing aids carry a rating of IP67 or IP68, signifying the highest level of dust protection and high water resistance. The term “water-resistant” applies to ratings like IP67, meaning the device can withstand temporary immersion, typically up to one meter for 30 minutes. A truly “waterproof” device is typically rated IP68, indicating protection against continuous submersion under manufacturer-specified conditions.
Even an IP68 rating does not automatically mean a device is safe for swimming. The force of swimming strokes or prolonged exposure to chemical-laden water may exceed standard test conditions. This rating is often a safeguard against accidental drops, heavy rain, or intense sweating. Consumers must check the manufacturer’s specific guidelines, as protection against accidental shallow immersion is distinct from permission for regular aquatic activity.
Specialized Devices for Aquatic Environments
For individuals who require hearing assistance while actively participating in water sports, specialized solutions are available that offer true aquatic durability. Some manufacturers have developed rechargeable IP68-rated hearing aids specifically tested to withstand submersion in fresh, salt, and pool water. These devices utilize special coatings and sealed casings to prevent water penetration during active use.
Bone Conduction Systems
Another alternative involves using bone-conduction hearing systems, which bypass the outer and middle ear entirely, transmitting sound vibrations directly to the inner ear through the skull. These external processors are designed with enhanced water protection or are paired with waterproof accessories, allowing them to be worn while swimming.
Protective Earplugs
For users of standard hearing aids, a non-electronic solution is to wear custom-molded earplugs or swim molds. These protect the ear canal from water while the aids are safely stored. Protective plugs are particularly useful for those with ear tubes or recurring ear infections.
Emergency Care and Moisture Management
If a standard hearing aid accidentally gets wet, immediate action can often prevent permanent damage. First, turn the device off and immediately remove the battery to stop any electrical current that could cause a short circuit. After removing the battery, gently wipe the entire casing with a soft, dry cloth to remove visible surface moisture.
Users must never attempt to dry a hearing aid using a direct heat source, such as a hair dryer, as intense heat can melt or warp internal components. The most effective drying method is to place the device in a dedicated hearing aid dehumidifier or a drying kit containing desiccant capsules. These products safely draw out trapped moisture overnight. Regular preventative care should include storing the hearing aids in a dehumidifier nightly to manage daily moisture accumulation.
