研究发现：打针时盯着看会减少痛感
http://www.sina.com.cn 2011年02月12日 19:54 环球时报According to a recent research by scientists from the UniversityCollege London and University of Milan-Bicocca, looking at the injectionas it plunges into your skin will actually lessen how painful it feels。
Scientists applied a heat probe to the hands of 18 volunteers. Theyfound that the participants were able to withstand higher temperatureswhen they could see their hand in a mirror compared to when the imagewas obscured with a block of wood。
Magnifying the hand in a convex mirror cut pain levels furtherstill. Volunteers on average could tolerate 3C more heat when looking attheir hand than when they didn't。
Study co-author Patrick Haggard said: "We've shown there is aninteresting interaction between the brain's visual networks and thebrain's pain networks." As for the advice, he said:" My advice would beto look at your arm, but try to avoid seeing the needle - if that'spossible."
英国《每日邮报》11日报道，来自伦敦大学学院和米兰比可卡大学的科学家研究后得出结论，人们在打针时观看自己被“扎”的情景有助于缓解痛感。
科学家们在18个受试者手上用热探针进行了测试，结果发现，相比起那些面对着被木头堵住的镜子的受试者，得以在镜子中清除观看自己手部状况的受试者能够承受的温度更高。
而在凸面镜中看到自己放大了的手的受试者所感受到的痛感更轻。平均而言，了解了自己首部状况的受试者所能承受的温度比不清楚状况者承受的温度高了3摄氏度。
研究论文撰稿者之一帕特里克说道：“我们已经看到，大脑的视神经系统和痛觉网络之间存在着很有意思的联系。”至于给人们的建议，他这么说：“我的建议就是看着你的胳膊，别看针头——如果可能的话。”
