澳大利亚和中国科学家联合进行的一项研究表明,女性经常进行中等强度的劳动,如打扫卫生、操作真空吸尘器等家务劳动,可以降低其患卵巢癌的几率。这项研究一共调查了900名中国妇女。结果表明,一位妇女如果一周只做20分钟的家务,那么就基本上没有起到锻炼作用。但是,如果她每周做三四个小时家务的话,就可以降低其患卵巢癌的几率。 A study conducted jointly by Australian and Chinese scientists showed that women often perform moderate-intensity labor, such as cleaning and operating household appliances such as vacuum cleaners, which can reduce their risk of developing ovarian cancer. A total of 900 Chinese women were investigated in this study. The results show that if a woman only performs 20 minutes of housework a week, she basically has no exercise effect. However, if she does housework three or four hours a week, she can reduce her chance of developing ovarian cancer.
