in women could be remedied by acquiring a long-term stable marriage partner, a new study has suggested.
Research presented at the 23rd annual meeting of the Associated Professional Sleep Societies today (June 10th) has found that since the study began eight years previously, those women who already had, or since gained a husband were found to have better sleep than those who were not married.
The study looked at the sleep quality of 360 women of middle-age who were drawn from African-American, Caucasian and Chinese ethnic backgrounds.
Lead author Dr Wendy Troxel, assistant professor at the University of Pittsburg School of Medicine, commented: "Women who had 'gained' a partner over the eight years of the study had similar subjective sleep quality as compared to the stably married women.
"However, after looking at specific objective sleep measurements we discovered that these women had more restless sleep than the always married women."
She added that this phenomenon could be explained by the fact that women who were recently married are less used to sleeping in a bed alongside their husband, also attributing the difference to the "newlywed effect".
Another study to be presented at the annual meeting showed that women who become mothers for the first time are fatigued by fragmented sleep rather than the timing of sleep.
