Although a glass of wine or two in the evening can help you feel relaxed, it is proven to disrupt the quality of rest and have negative effects on brain function the following day according to new research.
The University of Melbourne conducted a study on 24 students, with equal numbers of men and women aged 18 to 21, which showed that non-rapid eye movement sleep was increased while alcohol "exerted an arousal influence" on the brain.
The experiment, involving tests with pre-sleep alcohol and a placebo, concluded that the lack of rapid-eye movement (REM) sleep caused by drinking can also debilitate a person's functions upon waking and for hours later.
The study was published in Alcoholism: Clinical & Experimental Research, and shows that cognitive functions ,such as memory and processing of information in the brain, is impacted by drinking the night before. Dr Nicholas, one of the authors of the study, concludes, "If sleep is being disrupted regularly by pre-sleep alcohol consumption, particularly over long periods of time, this could have significant detrimental effects on daytime well-being and neurocognitive function such as learning and memory processes."
