Summer heat, humidity, sweat, and outdoor activities can take a toll on hearing aids, but a few simple habits can keep them working their best. Wipe your devices with a soft, dry cloth after spending time outside to remove moisture, sweat, and debris. Always apply sunscreen, insect repellent, or hairspray before handling your hearing aids, and wash your hands first. Keep them away from direct sunlight and never leave them in a hot vehicle. Before charging, allow damp devices to air dry for several minutes, clean the charging contacts regularly, and charge them in a cool, dry room to help extend their lifespan.
