Humidity, sweat and rain shorten hearing aid life. A simple daily routine to protect your investment.
Quick answer
Humidity, sweat and rain are the leading cause of hearing aid failures during Indian monsoons. Wipe aids with a dry cloth every night, open the battery door or park rechargeables in the charger, use a dry-aid kit or electric dehumidifier weekly, never wear aids in the shower or heavy rain, and book a professional service every six months to keep wax filters, domes and receivers in good condition.
Key takeaways
- Moisture damage — not drops — is the #1 monsoon cause of hearing aid breakdowns.
- IP68-rated aids handle splashes but not sustained rain.
- Never use a hair dryer or microwave to dry an aid; heat destroys electronics.
- A weekly dry-aid kit doubles the average service life of the device.
- Book a professional clean and check every 6 months — sooner after monsoon.
Pune's monsoon humidity is brutal on electronics. A ₹80,000 hearing aid can develop microphone crackle in one monsoon season without a simple care routine.
Every night — the 60-second routine
- Wipe the shell with a dry microfibre cloth
- Brush the microphone port and wax filter with the supplied brush
- Open the battery door (or take out of charger for 30 min)
- Store in a drying kit or electric dehumidifier overnight
Every week
- Replace wax filter if speech sounds muffled
- Inspect the dome or ear-mould for debris
- Wipe the charging contacts with a dry cotton swab
What to avoid
- Never use tissue paper (leaves lint in ports)
- Never blow on the aid (moisture from breath damages the mic)
- Never leave in the car glovebox — heat kills batteries
- Never wear in the shower or heavy rain without a cover

Frequently asked questions
Are hearing aids waterproof?
Most are water-resistant, not waterproof. Many modern aids carry an IP68 rating, which means they cope with sweat, humidity and light rain, but not a shower, a swim or being submerged. Take them off before bathing or swimming, dry them straight away if you get caught in the rain, and park them in a dry-aid kit overnight during the monsoon. Treat 'water-resistant' as protection against everyday moisture, not permission to get them wet.
Can I wear hearing aids while sleeping or exercising?
Exercising, yes; sleeping, usually no. Sweat from a workout is fine for water-resistant aids as long as you wipe and dry them afterwards. For sleep, most people take their aids out: lying on them is uncomfortable, they can whistle against the pillow, and your ears benefit from a break. The exception is a device your audiologist has specifically set up for overnight use.
How do I protect my hearing aids in the monsoon?
Wipe the aids with a soft dry cloth every night, open the battery door (or park rechargeables in the charger) to let moisture escape, use a dry-aid kit or electric dehumidifier weekly, and never wear aids in the shower or heavy rain. Sweat and humidity are the biggest cause of monsoon breakdowns.
Can rain damage my hearing aids?
Modern IP68-rated hearing aids handle splashes and light rain, but sustained rain, water pooling in the case or getting caught in a downpour can still push moisture into the microphones and receivers. Cover the aids with a cap or umbrella and dry them straight away when you get home.
What should I do if my hearing aid gets wet?
Switch the aid off, open the battery door or remove from the charger, wipe the outside with a dry lint-free cloth, and place it overnight in a dry-aid kit or airtight box with fresh silica gel sachets. Do not use a hair dryer or microwave — heat damages the electronics.
How often should I service my hearing aid?
A professional service every 6 months is ideal in India — more often during and after the monsoon. Your audiologist will replace wax filters and domes, clean receivers, test performance and pick up small issues before they become expensive repairs.
