Many new mothers suffer from extreme tiredness even four months after giving birth, prompting experts to warn they should not hurry back to work. An Australian study found half of new mothers were still "excessively sleepy" 18 weeks into motherhood. The findings have "significant implications" for decisions-makers about the length of parental leave, the researchers said.
Dr. Ashleigh Filtness, of Queensland University of Technology, studied the sleep patterns and tiredness in women after giving birth. She found that despite new mothers recording stable night sleep times at 18 weeks, they continued to report being excessively tired. The study, published in the journal PLOS ONE, followed 33 healthy new Australian mums who recorded their sleep patterns after giving birth in 15-minute intervals during weeks six, 12 and 18.
Dr. Filtness said, " Sleep disruption strongly influences daytime function, with sleepiness recognized as a risk-factor for people performing critical and dangerous tasks. Our findings bring into question whether four months’ parental leave is sufficient to ensure daytime sleepiness has diminished to a manageable level before returning to work. "
And while new mothers were still waking on average twice a night to attend to their babies at six, 12 and 18 weeks—their total sleep time was about seven hours and 20 minutes. Australian new mothers actually slept more than the average American ones, who got six hours and 53 minutes.
Dr. Filtness added, "While post-partum (产后的) women experienced disturbed sleep, they didn’t necessarily experience total reduced sleep time. What we found was that inevitably, new mothers will wake in the night to attend to their infants and the number of times they wake remains consistent during the first 18 post-partum weeks. Sleep disruption reduced over time and it appears this was driven by a reduction in the time it took for new mums to return to sleep, suggesting improved efficiency by mothers at settling their infants or the development of the infants’ circadian rhythm (生理节奏). " She added the findings highlighted the importance of sleep quality as opposed to sleep quantity—especially during the first 12 weeks.
Referring back to the length of parental leave a woman has, Dr. Filtness said, " It is important when developing regulations for parental leave entitlements that policy makers take into account the high prevalence of excessive daytime sleepiness experienced by new mothers. With the birth of every baby the new mother must adjust to the demands of parenting and one aspect of that is to remain functional while experiencing potentially severe sleep disruption. To put this into context, the assessment tool used to determine new mums’ sleepiness is also used by GPs to determine clinically relevant levels of sleepiness. If any other otherwise healthy person presented to a doctor with this degree of sleepiness they would likely have been offered advice regarding implications for daytime impairment including the impact on sustaining attention and decision making. " [br] What does the reduction of new mothers’ sleep disruption imply?
选项
A、Their total sleep time increased correspondingly.
B、They didn’t need to get their babies back to sleep.
C、Their babies didn’t wake up so often at night.
D、They realized the importance of sleep quality.
答案
C
解析
推理判断题。定位句指出,睡眠中断随着时间的流逝而减少,其原因似乎是新妈妈重新人睡所需的时间在减少,这表明妈妈们哄婴儿睡觉的效率有所提高或者婴儿的生理节奏得到了发展。由此可知,新妈妈睡眠中断的减少暗示着婴儿的生理节奏变得正常,夜间醒来的次数不再那么频繁,故答案为C)。A)“她们的总睡眠时间相应增加”,该段第一句提到尽管产后女性的睡眠受到干扰,但她们的总睡眠时间并不一定有所减少,也就是说,产后女性的睡眠是否受到干扰并不影响她们的总睡眠时间,因此不能推断出新妈妈睡眠中断减少就会令她们的总睡眠时间相应增加,故排除;B)“她们不需要哄婴儿重新人睡”,该段第二句提到睡眠中断的减少表明妈妈们哄婴儿睡觉的效率有所提高,而不是不需要哄婴儿重新人睡,该选项是对原文的曲解,故排除;D)“她们意识到睡眠质量的重要性”,该段最后一句提到研究结果强调了睡眠质量的重要性,而非睡眠数量,但这并未表明新妈妈们意识到了这一点,故排除。
