研究证实：狗可以闻出你是否紧张

狗狗不但能闻出糖尿病，闻出药品和毒品，还能闻出人类情绪的变化。新研究证实，狗可以通过嗅觉来识别一个人是否精神紧张。

狗鼻子可以灵敏到什么地步？狗狗不但能闻出糖尿病，闻出药品和毒品，还能闻出人类情绪的变化。新研究证实，狗可以通过嗅觉来识别一个人是否精神紧张。

Whether it’s a tricky maths problem or an unexpected bill, daily life is full of stressful experiences. Now researchers have found that humans produce a different odour when under pressure – and dogs can sniff it out.

无论是棘手的数学题还是意想不到的账单，日常生活中总是有各种事让人压力山大。如今研究人员发现，人类在压力下会产生一种不同的体味，而狗狗可以嗅到这种味道。

While previous studies have suggested canines might pick up on human emotions, possibly through smell, questions remained over whether they could detect stress and if this could be done through scent.

先前的研究表明，狗可以识别人类的情绪，可能是通过气味，但是对于狗狗能否通过气味识别人的精神压力还未有定论。

"This study has definitively proven that people, when they have a stress response, their odour profile changes,” said Clara Wilson, a PhD student at Queen’s University Belfast, and first author of the research.

该研究的第一作者、贝尔法斯特女王大学的博士生克拉拉·威尔逊说：“这项研究明确证实了人们在应对压力时体味会改变。”
