多频繁的性爱能令我们快乐?

发自伦敦——“性爱就像钱一样,” 约翰·厄普代克(John Updike)写道,“是个多多益善的东西”。然而事实证明这并非完全正确,至少在一夫一妻制的关系中并非如此。那么究竟多频繁的性爱才算足够?在 2015年,一群多伦多大学的心理学家们开始了对这个问题的探寻。

他们的研究中,“性爱的频率预示着更美满的生活,但越多并不总是意味着越好,” 艾米·穆斯(Amy Muise),乌利希·施马克(Ulrich Schimmack),和艾米莉·因佩特(Emily Impett)发现,事实上对那些普通夫妇来说存在一个精确的频率可以为生活带来正面影响:那就是每周一次。

这项研究发现,每月性生活少于一次与每周有一次性生活的人之间的幸福感差异要大于年收入2.5万美元与7.5万美元的人之间的差距。换句话说,频率高出四倍的性生活对受试者情绪的激励作用相当于每年增收5万美元。

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million.
