Scientists have proved what students have long suspected: Maths equations can actually trigger physical pain.

Regions of the brain linked with the experience of physical suffering were activated in those fearful of maths when they were presented with a tough equation, researchers have found.

The higher a person's anxiety of a maths task, the more it increases activity in regions of their brain associated with visceral threat detection, and often the experience of pain itself, according to researchers Ian Lyons and Sian Beilock, from the University of Chicago, who had their study published in the journal Plos One.

However, they say their study examines the pain response associated with anticipating an anxiety-provoking event, rather than the pain associated with a stressful event itself.

A maths task itself is not painful but merely the thought of it is highly unpleasant to certain people.

"Math can be difficult, and for those with high levels of mathematics-anxiety (HMAs), math is associated with tension, apprehension and fear," the authors said in their paper titled, When Math Hurts.

"Interestingly, this relation was not seen during math performance, suggesting that it is not that math itself hurts, rather, the anticipation of math is painful.

"These results may also provide a potential neural mechanism to explain why (people with) HMAs tend to avoid math and math-related situations, which in turn can bias (those with) high levels of mathematics-anxiety away from taking math classes or even entire math-related career paths."

"We provide the first neural evidence indicating the nature of the subjective experience of math-anxiety."

The researchers used 14 people with HMAs and 14 who had low levels of maths anxiety.

The subjects were then asked to complete word tasks and maths tasks.

Other forms of psychological stress, such as social rejection or a traumatic break-up, can also elicit feelings of physical pain.

科學家已經證實了學生們長期以來的猜測：數學問題真的會導致疼痛感。

研究人員發現，當遇到難解的數學問題時，產生的恐懼可能激活大腦中主管生理痛的區域。

一個人對數學題越焦慮，與感官威脅偵測有關的大腦區域就越活躍，感受到的疼痛就越劇烈。這項研究是由芝加哥大學的研究者伊恩-里昂和西恩-貝洛克做出的，研究結果發表在《公共科學圖書館—綜合》雜志上。

但研究者表示，他們的研究考察了參與一項可引發焦慮的事情導致的疼痛反應，而不是可引發焦慮的事情本身導致的疼痛反應。

數學題本身并不會讓人感到疼痛，但思考數學題會使一些人非常不愉快。
