Ear hygiene
If you put your finger in your ear, you may come across a yellowish or brownish substance which is the earwax. This is formed from secretions of the sebaceous and ceruminous glands of the skin, along with hairs and dirt.
Earwax has a protective action, lubricating the skin and preventing infection. In a way, you could say that the ears have their own system of cleaning and disinfection.
We should always keep our ears clean and dry, but we should NEVER use any cotton buds or other instruments for cleaning further in beyond the external ear.
