If you keep hearing things that aren't there, you're probably drinking too much coffee.
如果你總是幻聽,可能是因為咖啡喝太多。
Just five cups a day could be enough to make your ears play tricks on you, according to researchers.
研究人員稱,一天5杯咖啡就能讓你的耳朵不靈便。
In an experiment, volunteers who had consumed "high levels" of caffeine thought they were listening to Bing Crosby singing White Christmas even though the song was not being played.
試驗中,服用了“大量”咖啡因的志愿者認為自己聽到了Bing Crosby唱的《White Christmas》,而事實上這首歌并沒有播放。
The researchers described caffeine as "the most commonly used psychoactive drug".
研究人員稱咖啡因是“最常被使用的精神藥物”。
They said the study showed that the health risks of too much coffee need to be addressed.
他們還稱該研究表明,過量飲用咖啡導致的健康風險亟待解決。
In the tests, 92 volunteers were asked to listen to a constant fuzzy sound known as white noise.
測試要求92名志愿者聽一段不間斷的白噪音(用以掩蓋令人心煩的雜音的聲音)。
Professor Simon Crowe, of La Trobe University in Melbourne, said: "We also told them that within the white noise there may be parts of the song White Christmas and if you hear it, press a button. We didn't include White Christmas in the white noise but found that more people who were very stressed and had high levels of caffeine thought they heard the song."
墨爾本拉籌伯大學的教授西蒙•克羅稱:“我們還告訴他們,在白噪音播放期間,可能會有歌曲《White Christmas》的幾個片段,如果誰聽到了,就按下按鈕。事實上白噪音中并沒有《White Christmas》,但我們發(fā)現更多情緒緊張、服用大量咖啡因的人群稱自己聽到了歌曲片段。”
The team from the university's School of Psychological Sciences found that five cups of coffee a day was enough to trigger this.
這個來自拉籌伯大學心理科學院的研究小組發(fā)現,一天5杯咖啡便足以導致這種幻聽狀況。
