还有些人不以为然。印第安纳波利斯(Indianapolis)的网络商务经理霍利?凯尔(Holly Kile)说:“我很喜欢把耳朵掏干净。”她说,她每天用棉签掏耳朵,每隔几个月用耳烛吸一次耳垢,她12岁的儿子也是如此。她说:“我们通常会比赛,看谁掏出的耳垢最多。”
Doctors strongly discourage using cotton swabs or ear candling to remove earwax and say that unless it's causing bothersome symptoms, earwax should be left alone.
医生们强烈反对用棉签或耳烛清除耳垢,并称除非耳垢导致不良症状,否则应该不要去管它。
Officially known as cerumen, earwax is part of the ear's own cleaning system, designed to stop incoming dust, dirt, bacteria -- even bugs -- in the ear canal and ferry them out again. The wax and trapped debris are propelled along by the movements of the jaw, at about the same speed that fingernails grow. When it reaches the ear opening, the wax usually dries, flakes and falls out, often without the human host noticing.
耳垢的正式名称是耵聍,它是耳朵自我清洁系统的一部分,目的是阻止进入耳道的灰尘、污物、细菌──甚至是虫子──并把它们赶出去。耳垢和沉积的废屑被活动的下颚推动,它的增长速度和手指甲大致相同。当耳垢到达耳道口时,通常会变干、变薄并掉出来,且通常不会被人类注意到。
