加拿大魁北克大学的科研人员在一项研究中,要求男女各20名志愿者将一只手浸入滚烫的热水中,而且要忍耐尽可能长的一段时间,与此同时,他们会闻到各种不同的气味。科研人员发现,玫瑰或杏仁的香气能使女性的疼痛感显著降低,而男性却没有出现这种反应。醋发出的气味所起到的作用恰恰相反,还会使疼痛感略有增加。 In one study, researchers at the University of Quebec, Canada, asked each of the 20 volunteers, men and women, to dip one hand into hot, hot water and endure for as long a period of time as they would smell Different smell. Researchers have found that the aroma of rose or almond can significantly reduce the pain of women, while men did not react. Smell the vinegar gives the opposite effect, but also makes the pain slightly increased.
