Alcohol consumption and sleep quality: a community-based study

This community-based study analyzed alcohol consumption and sleep quality in 11,905 participants over six years. Higher alcohol intake, particularly hard liquor, correlated with poorer sleep quality, including shorter sleep duration, snoring, and increased risk of obstructive sleep apnea (OSA). Light and moderate drinkers showed fewer disruptions, but heavy drinking significantly worsened sleep outcomes. Alcohol's impact on the respiratory system and neuroimmune balance explains these findings. These results highlight the long-term effects of alcohol on restorative sleep and its potential contribution to health risks like cardiovascular disease and cognitive decline.

To improve sleep quality and overall health, reduce or avoid heavy alcohol consumption, particularly hard liquor. Focusing on moderate or no alcohol intake, combined with consistent sleep routines, can minimize risks like snoring, OSA, and disrupted sleep duration. While these findings are based on robust community data, further studies are needed to confirm mechanisms and refine recommendations across diverse populations.
