Insomnia and Alcohol
- Preventing deep, restorative sleep
- Increasing awakenings throughout the night
- Increasing duration of time to fall asleep
Insomnia from alcohol is not always immediate; for some people having a drink before bed can initially promote sleep. However, studies on alcohol insomnia have shown that after as little as three days of drinking before bed these benefits diminish. Even for people who state they feel having a drink at night helps them to sleep, research shows their sleep quality is decreased by drinking.
Thirty-three percent of the general population is estimated to live with insomnia while as many as 72 percent of people with an alcohol use disorder may have insomnia. Researchers have found that people diagnosed with insomnia are much more likely to report using alcohol to help sleep than people who only experience occasional sleep disturbances.
Perhaps the question is not can alcohol cause insomnia but how does alcohol cause insomnia. Alcohol has been found to disrupt the neurotransmitters, or brain chemicals, responsible for sleep regulation. Alcohol causes the muscles of the upper air passages to be more relaxed which is likely to increase snoring while decreasing sleep quality and total sleep time. For someone with another co-occurring disorder like sleep apnea, these effects are likely to be more severe.
- Increase in awakenings throughout the night
- Reduced length of deep sleep
- Reduced duration of restorative sleep
Alcohol withdrawal insomnia is so common that it is one of the diagnostic criteria for alcohol withdrawal. Insomnia from alcohol withdrawal generally begins within the first 6 to 12 hours after abstaining from alcohol. Insomnia from alcohol withdrawal is likely to persist through the initial period of abstinence. Insomnia after alcohol withdrawal may in some cases persist for months or years. Insomnia is one of the largest setback triggers for people in recovery from an alcohol use disorder.
Increased insomnia takes a toll on someone in recovery and without proper treatment returning to alcohol use may seem to be the only solution. Insomnia is treatable and if properly addressed can prevent someone in recovery from experiencing setbacks.
