In general, it is not recommended to sleep with hearing aids on. Most hearing aids are not designed for prolonged exposure to moisture, which can occur during sleep due to sweat or increased humidity. Additionally, wearing hearing aids for extended periods without breaks may cause discomfort or irritation to the ear canal. It's advisable to remove your hearing aids before sleeping to allow your ears to breathe and minimize the risk of skin irritation. Moreover, taking breaks from hearing aid use gives your ears a chance to rest. If you have concerns or specific reasons for wanting to wear hearing aids during sleep, it's recommended to consult with your audiologist for guidance based on your individual needs and the type of hearing aids you use.
