What benefits do cerumen and sebum have for the body?

Cerumen, or earwax, helps protect the ear canal by trapping dust, debris, and microorganisms, preventing infections and maintaining ear health. Sebum, an oily substance produced by sebaceous glands, moisturizes and protects the skin, preventing dryness and offering a barrier against bacteria and fungi. Both substances play crucial roles in maintaining the integrity of their respective environments, ensuring optimal functioning and protecting against external threats.
