A surprising new study concludes that menopausal women who sweat at night sleep longer and sleep more, the more difficult they are to think.
Previous studies have linked diurnal hot flashes to poorer memory. In this study, researchers examined sleep time and night sweats in women with a history of breast cancer.
To their surprise, investigators found that more frequent night sweats were associated with longer sleep – and the more sleep women had, the lower their ability to pay attention and reflect ("cognition"). However, the study found only one association and could not prove a cause-and-effect relationship.
The sleep time, however, did not affect the memory. In addition, researchers noted that daytime hot flashes did not affect total sleep time.
"This work presents new insights into the influence of menopausal symptoms on cognitive performance in women with a history of breast cancer and raises the possibility that hot-flash treatments may be beneficial for cognition. these women through their effects on sleep, "said senior author John Bark in a statement. press release of the North American Menopause Society.
Bark is a PhD student in behavioral neuroscience at the University of Illinois at Chicago.
The results are to be presented this week at a meeting of the North American Menopause Society in Chicago. Research presented at meetings is generally considered preliminary until it is published in a peer-reviewed journal.
