Earwax, or cerumen, is often seen as something dirty that needs to be removed,

but in reality it plays an important protective role in the body. It traps dust and bacteria, protects the ear canal from dryness, and even has mild antibacterial properties. Normally, it moves out of the ear naturally, but problems often begin when people overclean their ears or use cotton swabs, which can push wax deeper and cause blockages. Doctors explain that earwax can also reflect small changes in overall health. While normal wax ranges from yellow to dark brown, unusual changes in color or texture may sometimes give subtle clues about what is happening inside the body.
