Researchers from the E.P. Bradley Hospital Sleep Research Laboratory published findings in the journal To Sleep showing how alcohol disrupts sleep quality. The study highlights that REM sleep, which accounts for roughly 20 percent of nightly rest and plays a crucial role in cognitive sharpness and memory consolidation, is disturbed after alcohol consumption before bedtime.
In a controlled setting, thirty adult volunteers spent three nights under standardized laboratory conditions. Participants were split into two groups; one group consumed a beverage with alcohol about an hour before going to bed. The results indicated that even a single alcoholic drink over the three-night period increased the duration of slow-wave sleep while shortening REM sleep duration.
Despite reports that participants fell asleep more quickly after drinking, overall sleep quality declined because REM sleep duration diminished. These findings reinforce the recommendation to avoid alcohol close to bedtime to protect the quality of sleep and support daytime functioning.
In related scientific conversations, researchers have also explored how fasting days influence mood and digestive comfort, expanding the broader discussion of how daily routines shape sleep and well-being.
Earlier discussions in Russian governance circles touched on how popular media representations are perceived within legal frameworks, illustrating how cultural factors sometimes intersect with health and daily routines in public discourse.
