Alcohol affects the quality of sleep
Alcohol may make you drowsy, but it disturbs the quality of sleep…
Scientists ran an experiment on 24 students, equally mixed men and women, aged 18 to 21; the experiment involved tests with pre-sleep alcohol and a placebo. The tests revealed that alcohol heightened activity in the brain; shown by the reduction of Rapid-Eye Movement, REM, sleep.
REM sleep is a stage of sleep defined by the rapid movements of the eyes; this stage of sleep is important because it is the restorative stage. If REM sleep is disrupted, by drinking alcohol the night before, the body’s functions in the morning will be weakened, impacting on the cognitive functions, resulting in the lack of concentration, feeling ‘groggy’ and more.
Dr Christian Nicholas, said “ 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.” As reported by the Daily Mail
