      What is earwax?

      Earwax is a secretion produced by special glands in the outer ear canal. It is produced by humans and most mammals. It can either be dry and flaky or sticky and wet. It can range in colour from being yellow or orange to reddish or dark brown.

      Why do we need earwax?

      Earwax has many important jobs. It moisturizes the skin of the ear canal to prevent dry and itchy ears. It also contains special chemicals that fight off infections and acts as a protective layer that keeps the eardrum safe.

      Can earwax create a blockage?

      In most humans, the earwax naturally falls out of the ear canal and is washed away when we bathe. As the ear canal constantly creates earwax, the skin is always moisturized and protected. However, sometimes there is an excessive build-up of earwax which can cause earaches and a mild loss of hearing. It is best to go visit a doctor, who can provide ear drops or safely remove the wax.

      Using earbuds only pushes the earwax deeper and can cause a blockage or damage to the eardrum.

      什么是耳垢?

      耳垢是外耳道特殊腺體分泌的分泌物。人類和大多數(shù)哺乳動(dòng)物都會(huì)產(chǎn)生。它可能是干的、片狀的,也可能是粘的、潮濕的。它的顏色不一,從黃色或橙色到紅色或深棕色都有。

      為什么我們需要耳垢?

      耳垢有許多重要的作用。它能滋潤(rùn)耳道皮膚,防止耳朵干燥發(fā)癢。它還含有抗感染的特殊化學(xué)物質(zhì),起到保護(hù)層的作用,保護(hù)耳膜。

      耳垢會(huì)造成阻塞嗎?

      大多數(shù)人的耳垢會(huì)自然地從耳道中掉出來,在我們洗澡時(shí)被沖走。由于耳道不斷產(chǎn)生耳垢,皮膚總是得到滋潤(rùn)和保護(hù)。然而,有時(shí)耳垢堆積過多,會(huì)導(dǎo)致耳痛和輕度聽力喪失。最好去看醫(yī)生,醫(yī)生可以為你開些滴耳藥或者安全地清除耳垢。

      使用耳塞只會(huì)將耳垢推得更深,并可能導(dǎo)致耳膜堵塞或受損。
