Avoid Cold Hearing aids can function well when outdoors, even during the winter. However, after extended periods in the cold, the battery may loose power. If this occurs, just let the aid naturally return to room temperature and power should be restored. Avoid Moisture Hearing aids should not be worn in or near saunas, steam baths, regular baths, vaporizers, or showers. Protect the hearing aid from rain or snow.
Perspiration can also damage the hearing aid.
If the hearing aid gets wet, let it dry naturally with the battery door left open. Never dry a hearing aid with a hair dryer or put it in an oven of any kind. If your hearing aid does not begin functioning properly after it dries, contact your audiologist. As a general rule, it is best to keep your hearing aids away from water and moisture as it can cause serious problems with your aids. It is best to not wear your hearing aids when applying hair spray.
