22 Jul How Alcohol Affects Your Sleep
Less restful sleep
Alcohol may be a depressant that holds with it the potential to induce sleep more quickly, but that doesn’t mean that the sleep you’ll get is restful for the body. While you might sleep more soundly for the first half of the night as you experience deep sound wave sleep, your body at this stage is being deprived of rapid eye movement (REM) sleep, which is necessary for the restorative effects it has on the body. The second half of the night will be characterized by much lighter sleep, and you’ll awaken much more easily. This is likely due to the “rebound effect” that occurs in the middle of the night once alcohol has fully metabolized, which is the body’s way of making up for the REM deficit incurred during the first portion of sleep.
In other words, alcohol use creates an imbalance in the amount of REM sleep a person experiences, and studies have shown that it even creates a deficit in the overall amount of REM sleep that a person gets. This makes for an overall decrease in sleep quality.
Alcohol use can also result in (or worsen) sleep apnea, which is characterized by brief 10- to 30-second episodes of breathing obstruction (called apneas) while sleeping. This is because alcohol is a muscle relaxant, and after drinking the muscles at the back of your throat might ease even more than usual during sleep. These apneas can occur hundreds of times during a night of sleep and can result in daytime sleepiness, headaches, impaired mental functioning, or very loud or interrupted snoring.
The effects that alcohol can have on you while you are sleeping can also contribute to daytime sleepiness, which is characterized by excessive feelings of fatigue, decreased ability to function mentally, and decreased alertness during the day. Daytime sleepiness can interfere with everyday tasks like work and child care and causes a person to want to nap repeatedly, which in turn works to disrupt a sleeping cycle even further.
