Traffic Noise Might Hurt Your Brain
道路噪音或增加患脑部疾病风险
最近一项大规模研究显示，长期暴露于嘈杂的道路交通噪音中，患帕金森病的风险会随之增加。这是因为噪音会干扰睡眠并导致压力荷尔蒙增加，随着时间的推移可能会对大脑造成损伤。虽然目前还不能断定噪音是直接诱因，但研究表明，在家里保留一间安静的房间就能有效降低这种风险。

Quiz 🧠
Q1. Living near loud traffic for many years can harm your brain health.
查看答案
✅ True
持续的噪音会升高压力激素并干扰睡眠，久而久之可能会损害大脑健康。
Constant loud noise raises stress hormones and disrupts sleep, which can damage the brain over time.
Q2. What does 'disrupt' mean in 'noise disrupts our sleep'?
查看答案
✅ interrupts
'Disrupt'的意思是打扰或中断某件事，使其无法正常进行。
'Disrupt' means to interrupt something and stop it from continuing normally.
Q3. How does a quiet room at home protect your health from traffic noise?
查看答案
✅ By lowering stress
安静的空间有助于良好睡眠，并能降低对大脑有害的压力激素。
A quiet space helps you sleep well and lowers stress hormones that can harm the brain.
Dialogue 🎧
James: Charlotte, I think I need to move. My street is just too loud lately.
James: 詹姆斯，我觉得我得搬家了。最近我家门前的路边实在太吵了。
Charlotte: Well, that noise might actually be worse for your brain than you think.
Charlotte: 哎呀，那种噪音对大脑健康的危害可能比你想象的要严重得多。
James: Wait, what? Are you trying to scare me now?
James: 啊？怎么突然说这个？你是在吓唬我吗？
Charlotte: A massive new study links loud traffic noise to a higher risk of Parkinson's.
Charlotte: 最近有一项大规模新研究，说嘈杂的交通噪音会增加患帕金森病的风险。
James: Parkinson's disease? No way, that is a movement disorder.
James: 帕金森病？不会吧，那不是一种运动障碍疾病吗？
Charlotte: It is. Researchers followed over three million Danish adults aged forty and over.
Charlotte: 没错。不过研究人员对 300 多万名 40 岁以上的丹麦成年人进行了追踪调查。
James: Three million people? For how long did they study them?
James: 300 万人？那调查了多久啊？
Charlotte: For eighteen years. It was just published in Jama Neurology.
Charlotte: 整整 18 年。研究报告刚刚发表在《美国医学会杂志·神经病学卷》(Jama Neurology)上。
James: Okay, that's a huge study. So, how much noise increases the risk?
James: 哇，真的是很大规模的研究。那噪音要到什么程度风险才会增加呢？
Charlotte: For every eleven and a half decibel rise, the risk rose by three percent.
Charlotte: 据说噪音每增加 11.5 分贝，风险就会升高 3%。
James: Three percent? That sounds small, but over a lifetime it really adds up.
James: 3%？虽然看起来不多，但如果考虑到一辈子都在这种环境下，确实不能忽视。
Charlotte: Exactly. Especially since chronic traffic noise affects nearly one-third of Europeans.
Charlotte: 是啊。尤其是将近三分之一的欧洲人都饱受慢性交通噪音的困扰。
James: But how does sound damage your brain? Is it the loud physical vibration?
James: 不过声音是怎么伤害大脑的呢？是因为声音的物理震动吗？
Charlotte: Close, but it is actually sleep disruption. Constant noise raises your stress hormones.
Charlotte: 差不多。但实际上是因为干扰了睡眠。持续的噪音会使压力荷尔蒙水平升高。
James: Oh, like cortisol! And those stress responses damage brain cells over time.
James: 哦，就像皮质醇那种？这种压力反应随着时间的推移会损伤脑细胞。
Charlotte: Precisely. But some outside scientists warn it does not prove direct causation.
Charlotte: 完全正确。不过一些外部科学家也提醒说，这并不能证明两者之间存在直接的因果关系。
James: Right, it is hard to separate noise from other things like lifestyle.
James: 也是。毕竟很难把噪音和生活方式等其他因素完全分开来考虑。
Charlotte: True. But the study shows a simple way to protect yourself at home.
Charlotte: 没错。不过研究里提到了一个可以在家里保护自己的简单方法。
James: Tell me quickly! I need to protect my brain.
James: 快告诉我！我得保护好我的大脑。
Charlotte: Just having one quiet room in your house can help lower the risk.
Charlotte: 据说家里只要有一个安静的房间，就能帮助降低这种风险。
James: I love that. I am turning my bedroom into a silent sanctuary tonight.
James: 那太好了。从今晚开始，我要把卧室打造成世界上最安静的避风港。
Charlotte: Me too. Now we just need governments to cut down noise on main roads.
Charlotte: 我也是。现在就看政府能不能采取行动，减少主干道的噪音了。
