Can you wear earplugs while sleeping at night?
Generally speaking, whether it's appropriate to wear earplugs while sleeping at night depends on individual factors such as ear health, personal needs, and the type of earplug used. If there are existing ear discomforts or special concerns, it is advisable to consult a doctor or a professional. The specific considerations are as follows:

If there are no ear conditions such as inflammation or allergies, and you are in a noisy environment or have light sleep that is easily disturbed by sounds, wearing earplugs can be beneficial. Choose soft earplugs from reputable manufacturers that fit comfortably in the ear canal. Wash your hands and clean the earplugs before use, and avoid inserting them too tightly to prevent excessive pressure on the ear canal. When used properly, earplugs effectively block noise, improve sleep quality, and do not place significant strain on the ears.
Earplugs should not be worn if there is ear canal inflammation, discharge (pus), or skin damage. Using earplugs in such cases may obstruct ventilation in the ear canal, cause accumulation of secretions, and worsen infections. Individuals who are allergic to earplug materials, or those using earplugs that are ill-fitting or too rigid, should also avoid their use, as these may lead to itching, swelling, or even damage to the ear canal skin and eardrum, thereby compromising ear health.
Clean earplugs promptly after each use and replace them regularly to prevent bacterial growth. Gently wipe the outer ear with warm water daily and keep the ears dry and clean. Avoid using sharp objects to clean the ear canal. If ear discomfort occurs after using earplugs, discontinue use immediately. Seek medical attention promptly if symptoms persist. Developing good habits is essential for maintaining healthy ears.
