A study finds that in the 10 days before their periods began women were more likely to go on a spending spree, which is called shopping period. Psychologists believe shopping could be a way for premenstrual women to deal with the negative emotions created by their hormonal changes.

一项研究发现，女性在生理期到来前十天更易大肆购物，这种现象叫做“购物生理期”。心理学家认为，购物可能是女性应对生理期到来前因荷尔蒙变化而产生的负面情绪的一种方法。

Women are buying items to make themselves feel more attractive - coinciding with the time of ovulation when they are most fertile, typically around 14 days before the start of a period. Most of the purchases made by the women were for adornment, including jewelry, make-up and high heels.

女性倾向于在排卵期，即生理期到来前14天左右，购买一些让自己更有魅力的产品。她们在这期间购买的大部分都是装饰类物品，比如珠宝、化妆品以及高跟鞋等。
