有许多人认为爱会带来伤痛,但两位美国大学的研究专家得出的结论是“爱”能缓解疼痛。

Contemplating1 a new love can reduce pain by activating2 the same brain region that processes addictions3 and analgesic4 drugs. Cynthia Graber reports

Singer: “Love Hurts.”

That ’80s power ballad5 had it all wrong. Love may keep you from hurting.

Two researchers—pain specialist Sean Mackey at Stanford and love specialist Arthur Aron at S.U.N.Y. Stony6 Brook—met at a neuroscience conference. They realized they were talking about the same brain region.

So back at Stanford, researchers recruited 15 undergrads in the early euphoric throes of a relationship. The volunteers had photos of the romantic partner and of an attractive acquaintance. As they looked at the photos, their palms were safely heated to mild pain. Then the volunteers repeated the experiment but were distracted by tasks such as: think of sports that don’t use balls. Previous research found that distraction7 can ease pain.

Both distraction and the pictures of new loves reduced pain. But, the love photo acted in a totally different area of the brain—the primitive8 reward system region that lights up where addictive9 drugs work, and where pain-relieving opioids do their magic. The study was published in Public Library of Science One. [Jarred Younger et al., Viewing Pictures of a Romantic Partner Reduces Experimental Pain: Involvement of Neural10 Reward Systems]

So the next time you’re in pain, maybe you don’t need to pop a pill. Just fall in love.
