&gt; <i>In conclusion, earplugs are the best investment you can get.</i><p>Careful with that. Wearing earplugs every day for an extended duration (like while sleeping) might cause issues with the inner ear. I did that and ended up suffering from vertigo for a while. Discontinuing the use of earplugs made the symptoms gradually disappear. Starting to use earplugs again made vertigo come back. Repeat for a few cycles.<p>I have stopped using earplugs while sleeping. Brief usage (like when using loud machinery) seems fine.<p>I&#x27;m sure everyone is different and not all people will suffer from inner ear issues from earplugs, but keep this in mind.
