Tips for keeping hearing aids and ears protected during the winters.. As the winter season continues and the temperature keeps dropping, we must protect our hearing devices and our ears. Following are some tips to keep them protected: 1. The cold weather may cause your hearing aid batteries to drain faster. Keep a spare with you if you will be out for a long time. Keep your spare batteries in a warm place, if possible. Batteries can be warmed in your closed hand for a few minutes before use if they get cold. 2. Only use drying containers made for hearing devices. Do not use heaters or hair dryers to dry your hearing aids. 3. Never stick anything in the ears to keep them warm. You may damage the hearing aid and cause inflammation in the ear canal. Keep safe and keep warm!
