this is a very interesting question that has quite possibly a simple answer. gently plug your ears with your fingers and breathe heavily through your nose for a moment or two. can you hear yourself breathing? most people can. that's because plugging your ear canal blocks outside noise from being transmitted through the nerves of the ear to the brain. instead your ear hears your body's internal sounds like breathing. it's possible your headphones are blocking external noise and allowing your ears to hear your body's sounds instead. if you're playing music through your headphones at a low sound level your ears will continue to pick up your breath sounds. while you may actually be breathing in a labored fashion when you put headphones on (such as if you're exercising) chances are it just sounds that way to you because you're not used to hearing your normal breath sounds. of course if you feel short of breath or feel you have trouble breathing then by all means you should see a doctor. if you're otherwise healthy and not having additional symptoms you may not need to get this checked out. as always though if you have any concerns about your health especially your breathing you should consult a medical professional. hope this helps! i thought i was the only one. i think it also deals with metaphysics. being an empathetic - u pick up on people's energies and sending out anxiety into overdrive. i'm still looking into myself.
why when i hear headphones does my breath gets loud and i have labored breathing?
