(These may be micro-awakenings that the sleeper doesn’t even remember—but they still interrupt the flow, and quality, of sleep.) During the second half of the night, sleep architecture shifts again away from normal, with less time spent in slow wave sleep. The rebound effect may include more time in REM—a lighter sleep stage from which it is easy to be awakened. If you fall asleep after drinking too much, your body will continue to break down the alcohol during the night. As your body works to lower your blood alcohol level, you may experience disrupted sleep and wake up more often than usual.
Here’s How Alcohol Affects Your Sleep
Statistical models were constructed to determine the extent to whichcortical and subcortical volumes could predict evoked potential component amplitudes insleeping alcoholics and controls. Stepwise multiple regression entering age, intracranialvolume, diagnosis, lobar gray matter volumes and subcortical tissue volumes to predictN550 amplitude at Fz produced different models in men and women (Colrain et al. 2011). For men, sensorimotor gray matter volumemade a significant independent contribution to N550 amplitude with the amount of varianceexplained significantly improving with the addition of diagnostic group. These datasupport the hypothesis that diminished gray matter volume in chronic alcoholismcontributes to an impaired ability to generate large amplitude slow waves, although notall the variance could be explained by loss of volume. Poor connectivity (i.e., deficitsin white matter integrity) likely also contributes, although relations between evokedpotential amplitude and diffusion tensor imaging (DTI) measures of white matter integrityare yet to be tested.
Alcohol and Sleep Disorder
- Dr. Sengupta shares some of the not-so-obvious effects that alcohol has on your body.
- However, once the body realizes it’s had too much slow wave sleep, the homeostatic drive compensates by allowing us less deep sleep in the second half of the night.

- Studies of the effects of repeated alcohol administration over multiple nightsare rare and suffer from small sample sizes.
- Young men and women in this age group are also at risk of drinking-related injury, property damage, date rape, and unsafe sex while under the influence of alcohol.
- While your internal clock regulates the kidney’s release of electrolytes and works to filter fluids, alcohol inhibits these processes.
“It can increase estrogen levels which might increase risk of breast cancer in some women,” Lee says. Your liver detoxifies and removes alcohol from your blood through a process known as oxidation. When your liver finishes that process, alcohol gets turned into water and carbon dioxide.

The gut and its microbiome are often referred to as the body’s second brain, and operate under powerful circadian rhythm activity. The circadian disruption that can result from alcohol consumption contributes to leaky gut syndrome, according to research. Circadian rhythms thrown out of sync can weaken the lining of the gastrointestinal tract, making it more vulnerable to permeation—that’s the leakiness that allows bacteria, toxins, and food to leave the intestines and enter the bloodstream. Heart rate variability (HRV) and resting heart rate are two of the most useful metrics for quantifying your fitness on a daily basis. Consuming alcohol causes your HRV to drop (bad) and your resting heart to rise (also bad). With the WHOOP Journal feature, our members are given the option of noting whether or not they have any alcoholic drinks each day.
Heavy drinking can make the sleep- and circadian rhythm-disrupting effects of alcohol worse. But even a regular, moderate routine of two to three drinks a day is enough does alcohol help you sleep to create sleep and performance problems for many people. It’s not because I don’t appreciate a glass of wine with a great meal, or a few beers on a hot summer evening.
