Can Earplugs Be Harmful in Sleep?

• The little sponge earplugs are designed to sit in the external ear canal and they should not be pushed in too far since they will act as ramrods, packing wax and debris deep inside the ear canal and possibly against the eardrum. 
  
  
• Pushing in earplugs into the external ear canal may cause the air pressure to rise in it, in effect pushing against the eardrum and causing pain. This may be caused by pressure on the ear while lying down on the side, and is also the case when completely expanded foam earplugs are pushed further into the ear. To bypass the latter risk, such earplugs are instead removed, compressed and inserted to the desired depth. Vice versa, when pulled out, the resultant negative pressure pulls the eardrum. Therefore, some earplugs are better carefully screwed or jiggled out rather than yanked out. Yawning does not help to equalize this air pressure difference, since it equalizes the pressures between the middle ear and the environment, while this overpressure rather is located in the outer ear, between the eardrum and the earplug.
  
  
• There is a possibility of allergic reactions, but this is likely rare, as earplugs generally are made of immunologically inert materials.
