An Alcoholism: Clinical & Experimental Research report reveals that alcohol before bed can cause disruptions in sleep.

“For individuals researching sleep in the field of alcohol studies,¬†our findings indicate that care needs to be taken when interpreting increases in ‘visually scored’ SWS (slow wave sleep) associated with alcohol consumption,” aid¬†Christian L. Nicholas, National Health & Medical Research Council Peter Doherty Research Fellow in the Sleep Research Laboratory at The University of Melbourne. “Increases in SWS, which traditionally would be interpreted as a good thing, can be associated with more subtle changes indicating disrupted sleep, such as the increases we observed in alpha activity, which are revealed when more detailed micro-structural components of the sleep electroencephalogram are assessed.”
