Photographs of loved ones have the power to dull pain, scientists have discovered.
科学家发现，恋人的照片有减轻疼痛的功效。
Researchers found that an image of a romantic partner dulls activity in the pain-processing areas of the brain, to the same degree as paracetamol（扑热息痛） or narcotics（麻醉剂） such as cocaine.
A study by Stanford University found direct evidence linking feelings of emotional attachment with the soothing（抚慰的） of pain.
The brains of lovestruck（热恋中的） students were subjected to MRI scans as they focused on photographs of partners while varying levels of heat pain were applied to their skin.
Neuroscientist Jarred Younger found, on average, pain was reduced by between 36 and 44 per cent, with intense discomfort eased by up to 13 per cent.
In a study published in the US journal Public Library of Science, the post-doctoral scholar said: 'The reduction of pain is associated with higher, cortical（皮质的） parts of the brain.
'Love-induced analgesia（止痛） is much more associated with the reward centres.
'The region tells the brain that you really need to keep doing this. This tells us that you don't have to just rely on drugs for pain relief.
'People are feeling intense rewards without the side effects of drugs.'
In a separate analysis, psychologists studied 25 women and their boyfriends of more than six months, subjecting them to different levels of pain, using a sharp, prickling（针刺痛） sensation.
During the various 'stimulations', the women either held their boyfriend's hand or the hand of a male stranger, both of whom were hidden behind a curtain.
In other cases, the women were asked to view a photograph of their boyfriend, or a picture of a male stranger while being subjected to discomfort.
Researchers at the University of California, where the study took place, discovered the women showed significantly reduced pain experience while holding their partner's hand.
But surprisingly, the photograph of their romantic partner provided equally effective pain relief, and both cases were far greater than when a stranger was involved.
