醫院噪音不利於身體恢復

Many who need restorative rest most might not be able to get it. Why? They're in a hospital. Even at night, a hospital can be a noisy place. And research has shown that these noise levels have been rising for decades.
許多處於恢復期、最需要休息的人可能睡不好覺。爲什麼？因爲他們在住院。即使到了晚上，醫院也可能是很嘈雜的地方。研究表明幾十年來，醫院的噪音水平一直在上升。

A new study finds that electronic noises in particular interfere with sleep.
一項研究發現，電子噪音尤其會干擾病人休息。

Researchers followed the sleep patterns of a dozen healthy volunteers as they spent three nights sleeping in a lab. Their hours of darkness were punctuated with 14 different recorded hospital sounds played at varying volumes. Even when electronic sounds, such as alarm beeps, were played at the level of a whisper, volunteers
slightly roused from sleep. The findings are in the journal Annals of Internal Medicine.

研究人員讓12名身體健康的志願者連續三天睡在實驗室，並跟蹤了他們的睡眠模式。當以不同的音量播放14種不同的醫院錄音時，他們的黑暗時間就推遲了。即使輕聲播放電子聲音，例如報警器的嗶嗶聲，志願者們還是會從睡夢中吵醒。這項研究發表在《內科醫學年報》上。
When the volunteers' sleep was disrupted, their heart rate increased. This frequently elevated heart rate could be especially bad for recovery. A little peace and quiet could make for a lot more restful nights.

當志願者的睡眠遭到打擾時，他們的心率就會加速。而頻頻出現心率加速則不利於身體的恢復。安靜一點能帶給你更多安寧的夜晚。
