The results of a study to be published in February´s online edition of Alcoholism: Clinical & Experimental Research, reveals that consuming alcohol before going to bed can result in sleeping disorders and problems.
The authors of the study say that “People tend to focus on alcohol and its commonly known sedative properties, which is reflected in shorter times to sleep, especially in adults, rather than sleep disruption that occurs later in the night”, said Christian L. Nicholas, expert in sleep research at the University of Meloburne, Australia.
In people who drink before bedtime, alcohol initially acts as a sedative, marked by the activity of the delta frequency in the electroencephalogram (EEG) of SWS, but later is associated with sleep disruption. Also, significant decreases in the activity of the delta frequency and power with normal development between the ages of 12 and 16 are produced.
The study involved 24 participants (12 women and 12 men) all healthy and aged between 18 and 21 years of age. They were social drinkers who consumed less than seven standard drinks per week for the past 30 days. Each individual underwent two situations: alcohol intake before bed as well as a placebo, followed by standard polysomnography with integrated EEG recordings.
The results showed that if sleep is regularly interrupted by alcohol before bedtime, especially for long periods of time, this could have significant negative effects on welfare during the day and neurocognitive function such as processes of learning and memory.
Alcohol does not help you sleep, according to Nicholas, “The main message is that alcohol is not really good for sleeping even though it may seem that helps you fall asleep faster. In fact, the quality of sleep you get is significantly altered and disturbed,” he concludes.
