Hazards of sleep soundproof earmuffs

The use of earplugs can cause earwax to be pushed into the middle ear while the earplug is inserted into the ear canal, which can cause tinnitus and reduce hearing, pain or bacterial infection. Users with excessive earwax should use earplugs more carefully, and earplugs should always be washed with water and mild soap. However, foam-type earplugs are usually discarded after being used up, and they may lose the characteristics of slow rebound after being soaked in water.

In addition, anti-noise earplugs may also be a trigger for otitis, because in a warm, humid environment, many bacteria will multiply more vigorously.

However, the use of noise-proof earplugs is usually safe, but some potential hazards that may arise from long-term use must be prevented:

Insertion of the earplug causes the air pressure in the middle ear to rise and pushes the eardrum to cause pain because the earplug is inserted too deeply. To avoid this danger, first loosen the earplugs and insert them into the desired ideal position. When the earplugs are fully inflated, it is best not to push them in. Vice versa, in order to avoid the ear drum being squeezed when pulling out the earplugs, slowly unscrew the earplugs instead of pulling them out.
