Why should you stop cleaning your ears with cotton swabs?
Your ear is already a self-cleaning machine, and the swab is fighting it.
The skin in your ear canal slowly grows outward and, helped by jaw movement when you chew and talk, carries old wax to the opening where it falls or wipes away on its own. Push a cotton swab in and you tamp most of that wax back deep against the eardrum, risking a hard plug or even a tear.
After a shower you twist a cotton swab in each ear to feel clean, but most days you are packing wax inward instead of pulling it out.
Leave the ear canal alone and just wipe the outer ear with a towel.
Skipping the swab avoids the wax plugs and canal injuries that send people to the doctor.
Ear = a tiny conveyor belt that pushes wax out; the swab shoves it back in.
