I don't think it's bad.
I prefer running a fan which makes white noise that masks the other noises
as I am a terribly light sleeper too.
I bring earplugs with me whenever I travel because you never know.
Make sure you don't reuse the plugs too much or you they can get dirty and perhaps cause infection on the skin inside your ear.
I worked for 10 years in the factory noise part of my company and we taught people how to wear earplugs. that was a complaint we heard occasionally.
