Alcohol 'affects sleep quality' in young women23 July 2006 Having an alcoholic drink before bedtime does affect the quality of sleep of young women, a new study has confirmed. Previous studies have shown that drinking a moderate amount of alcohol before sleep results in disrupted sleep patterns in men, but this latest research by scientists at the Bradley Hospital Sleep and Chronobiology Laboratory and Brown Medical School in the US has also linked women to similar effects. Writing in the journal Alcoholism: Clinical and Experimental Research, the scientists examined the sleeping patterns of women aged between 22 and 25 who drank alcohol before going to sleep, over the course of three nights. By monitoring their brain activity during sleep using electroencephalograms (EEGs), the researchers found that, compared to those taking a placebo drink before bed, the women with alcohol in their system experienced reduced REM sleep, or dreaming. "Whether this sleep pattern is beneficial or harmful is unknown at this point. Although it may signal an initial consolidation of sleep, it might also be associated with difficulty waking in the event of an emergent problem, such as a fire or medical emergency," said author Eliza Van Reen. She added that more research is needed to discover the effects of other doses of alcohol and family history of alcoholism on sleep patterns. Related links
