Small amount of drink disrupts sleep, study finds

If you have ever felt tired the morning after the night before, you might be relieved to learn that even a small amount of alcohol disrupts your sleep.

New Irish research claims to be the first study to show that even low levels of alcohol consumption cut time asleep.

The research, published in international journal Alcohol and Alcoholism, said small amounts of drink “significantly” reduce the total time spent asleep and induce “waking fatigue”.
