sleep deprivation vs alcohol driving

Sleep deprivation impairs driving more than legal alcohol limits

A study comparing sleep deprivation and alcohol on driving performance found that 24 hours of wakefulness impairs drivers more than being slightly above the legal alcohol limit. Sleep deprivation leads to slower reaction times, reduced lane control, and attention lapses. Coffee fails to improve driving performance, and drivers tend to underestimate their level of impairment.

alcohol disrupts sleep

Chronic alcohol use disrupts sleep, contributing to dependence and relapse risk

Chronic alcohol use creates long-lasting changes in sleep architecture that persist even after abstinence. Alcohol initially reduces sleep latency and enhances slow-wave sleep, but later disrupts sleep quality. These sleep disturbances, especially insomnia and REM sleep abnormalities, significantly increase relapse risk in alcohol dependence. Treating sleep disorders may improve recovery outcomes.
