Earwax, also known as cerumen, is a natural substance produced by glands in the ear canal. It helps protect the ears by trapping dust, dirt, and other small particles, preventing them from reaching the eardrum. Earwax also has antibacterial properties, which help keep the ears healthy and free from infections. Most people produce earwax in varying amounts, and it usually moves out of the ear naturally. However, sometimes it can build up and cause blockages, leading to discomfort or hearing issues. If this happens, it's important to consult a healthcare professional for safe removal rather than trying to clean the ears with cotton swabs.
