Understanding Alcohol-Related Sleep Disorders: Insomnia, Sleep Apnea, and Other Disturbances

If you’re reading this, perhaps you’re tossing and turning at night, struggling to fall or stay asleep. Maybe, you’re waking up feeling tired instead of refreshed, or perhaps, your loved ones are feeling burnt out every day. Is alcohol involved in the daily routine? If it is, it might just be the culprit behind existing sleep disturbances. You don’t need to suffer from alcohol addiction or a substance use disorder to experience the negative effects of alcohol. That’s why we’re taking a deep dive into alcohol-related sleep disorders today.

Understanding Sleep Disorders


Sleep disorders are a broad category of conditions that affect our ability to sleep well regularly. There are more than 100 specific sleep disorders that have been identified, leading to daytime sleepiness, fatigue, and impaired daytime functioning. Moreover, sleep disorders may go undiagnosed in certain cases. People who have them might not recognise the symptoms. Some of the most common sleep disorders include insomnia, sleep apnea, and narcolepsy.

Good sleep is crucial, which is why The Providence Projects can include sleep-related therapies and treatment during your stay with us, as we understand why these disorders need to be tackled from their source. Further research shows us that alcohol may be a factor in developing sleep disorders.

Sleep; Why We Need It

Sleep isn’t simply a passive state of rest, but in fact an active and essential process that supports several critical aspects of our health and well-being. Our bodies, as well as our minds, depend on good, quality sleep for proper functioning. Here are a few key reasons why we need sleep:

Cognitive Functioning and Mood

Sleep supports mental sharpness and emotional well-being. It helps to consolidate memories, enhance learning and decision-making skills, and boost creativity. Lack of sleep can influence mood, leading to irritability, anxiety, and depression.

Physical Health

Sleep is critical to physical health as it allows the body to rest and repair. It supports healthy growth, aids tissue repair, and bolsters the immune system. Good sleep is also linked to improved cardiovascular health, as it assists in maintaining blood pressure and cholesterol levels.

Prevention of Health Problems

Good sleeping habits can lower the risk of numerous health problems, including obesity, diabetes, heart disease, and cancer. Proper sleep is also crucial for maintaining hormonal balance.

How Alcohol Affects Sleep

When it comes to alcohol and the brain, the connection runs deep. Alcohol interferes with the homeostasis of your brain’s sleep centres, disrupting the key neurotransmitter responsible for your rest and wake cycles. In other words, if you don’t sleep right, your body may not even recognise you ever fell asleep and continue to tire out. When we work with clients to improve their sleep patterns during alcohol addiction treatment and rehab, we have observed the numerous benefits of a healthier sleep regime. However, many factors may affect our sleep. Alcohol is often considered a relaxant that can induce feelings of sleepiness. However, consuming alcohol, particularly in excessive amounts, has been linked with poor sleep quality and duration. Alcohol can alter sleep patterns, leading to uneasiness and disrupted sleep.

One of the key ways that alcohol affects sleep is by disrupting the Rapid Eye Movement (REM) phase. REM is a restorative and essential stage of deep sleep where dreaming occurs. Many sources consider it the most important part of the sleep routine for humans. As alcohol levels drop later at night, your brain gets significantly stimulated, causing prolonged uneasiness.

Also, chronic alcohol consumption can trigger or aggravate pre-existing conditions like sleep apnea, a sleep disorder characterised by interruptions in breathing during sleep. Alcohol acts as a depressant, relaxing the muscles in the upper airway and leading to an increased risk of sleep apnea or worsened symptoms for those with the condition. Furthermore, binge drinking or consuming large amounts of alcohol very quickly can significantly shift your melatonin levels–a hormone your body synthesises to help regulate sleep. This shift, which can last up to a week, can cause nightmares and headaches.

The Key to Overcoming Alcohol-Induced Sleep Disorders

But it’s not all bad news! You can take active steps to monitor and manage alcohol consumption before it becomes an addiction, keeping potential sleep disorders under control:

  1. Self-awareness and self-monitoring.
  2. Understanding the effects of alcohol.
  3. Seeking help when required.
  4. Implementing behavioural changes.
  5. Gradual reduction of alcohol consumption.
