The Summer Hearing Aid Survival Guide

Summer is finally here, bringing with it beach days, beer gardens, and outdoor adventures. But while you’re busy soaking up the sun, the season’s unique elements can take a quiet toll on your hearing aids.

From hidden humidity to unexpected dips in the pool, warm weather presents a few unique challenges for delicate digital tech. To help you enjoy a seamless, stress-free summer, we’ve put together the ultimate survival guide to keep your hearing aids performing at their best all season long.

Quick Summer Care Takeaways

• Prevent Moisture Damage: High humidity and sweat clog digital microphone ports; us an electronic hearing aid dehumidifier nightly and apply sun cream fully before inserting devices to avoid oil build-up.
• Avoid Extreme Heat: Never leave hearing devices in direct sunlight or hot cars, as extreme temperatures degrade battery life and warp internal circuitry.
• Water Exposure Emergency Steps: If a hearing aid gets wet, power it off immediately, remove the battery, and air-dry naturally. Never use a hairdryer or rice, as starch dust and high heat permanently damage components.

1. The Moisture Menace (Sweat, Humidity, and Water)

Moisture is the number one enemy of hearing aid electronics. Summer brings plenty of it, whether from a sudden afternoon downpour, high humidity, or just natural perspiration during a walk.

• Sweat and humidity can build up inside the battery compartment and microphone ports. Putting your devices in a dedicated electronic drying box (dehumidifier) overnight works wonders to safely draw out trapped moisture.

• Apply your sun cream, body lotion, or bug spray before putting your hearing aids in. Let the products fully absorb into your skin so oils and chemicals don’t coat the microphones or clog the vents.

• It sounds obvious, but it’s incredibly easy to walk straight into the sea or pool with your devices still tucked behind your ears. Make a habit of doing a quick "ear check" before getting near the water.

2. Beat the Heat

Just like smartphones and laptops, hearing aids are packed with sensitive microchips that don't mix well with extreme temperatures. High heat can warp plastic casings, degrade battery life, and damage internal circuitry.

• A car dashboard or glove compartment can quickly turn into an oven on a sunny day. If you need to take your hearing aids out while you're on the go, keep them in a protective case inside a bag that stays with you in the shade.

• When you aren't wearing them, avoid windowsills, conservatories, or anywhere that gets direct sunlight. Store them in a cool, dry place.

3. Keep the Grit Out (Sand and Dust)

Whether you’re heading to the coast or spending an afternoon gardening, fine particles of sand, dust, and dirt can easily find their way into the tiny openings of your devices.

• Avoid adjusting or touching your hearing aids if your hands are covered in sand, soil - or sticky melted ice cream!

• Use your cleaning brush every evening to gently clear away any debris before it has a chance to settle deep into the ports.

Caught in a Splash? The Emergency Plan

If the absolute worst happens and your hearing aid gets a proper soaking, don't panic. Follow these steps immediately:

1. Power Down - Turn the device off straight away. If it uses traditional zinc-air batteries, open the door and take the battery out.

2. Dry the Exterior - Gently wipe the outside with a clean, soft tissue or cloth.

3. Air Dry (Skip the Rice!) - Leave the battery door open and let it air dry naturally in a warm room. Do not put it in a bowl of rice (the fine starch dust can ruin the microphone), and never use a hairdryer or microwave, as the intense heat will melt the components.

4. Use Your Dehumidifier - Leave it in your drying box for an extended cycle.

If it still won't power up after 24–48 hours, it's time to bring it in for a professional look.

Keep Your Hearing Clear This Summer

Sometimes, what feels like a faulty hearing aid is actually just a build-up of Summer sweat mixed with natural ear wax, blocking the receiver.

If your devices aren't sounding quite as sharp as they should, or if you want to ensure your ears are perfectly clear before you jet off on holiday, we're here to help.
