Many of us know that alcohol can make us feel drowsy and relaxed. However, the extent of that effect and how it relates to the quality of our sleep may be less clear. Alcohol can have various impacts on the body, including the way we sleep, and understanding these effects is crucial to achieving healthy sleep habits. In this article, we’ll answer the question of whether alcohol makes you sleepy and explore its effects on sleep quality and quantity.

The Truth About Drinking Before Bed: Does Alcohol Make You Sleepy?

After a long day of work or socializing, many of us crave a drink or two to unwind. Alcohol interacts with multiple chemicals in the brain to enhance the effect of naturally occurring relaxing agents, like GABA. As a result, people tend to feel drowsy or even sleepy after drinking – especially after consuming a large amount – but this effect can wear off as alcohol is metabolized by the body.

While drinking can make you feel tired or drowsy, it can negatively impact the quality of your sleep. Alcohol consumption may cause you to wake frequently during the night and may increase the likelihood of snoring and other disruptive behaviors. Additionally, consuming alcohol before bed may cause you to fall into a deep sleep too quickly, bypassing the initial stage of the sleep cycle, and as a result, miss out on essential repair-rest time.

The Surprising Link Between Alcohol and Fatigue

Although alcohol may put you to sleep, it can also cause significant fatigue. It’s because alcohol is processed by the liver, and during this process, it generates adenosine. Adenosine is a naturally occurring chemical in the body that signals fatigue and sleep. Alcohol makes the brain unable to process adenosine, increasing fatigue. Alcohol consumption can also cause dehydration, which often leads to headaches and grogginess the next day.

As consumption continues to inhibit the liver’s ability to eliminate toxins, it keeps users feeling lethargic and sluggish. Hence, people who drink regularly may feel exhausted frequently and have difficulty maintaining consistent levels of energy.

The Dos and Don’ts of Drinking Alcohol Before Bed

If you plan to consume alcohol before bed, here are some tips to avoid disrupting your sleep:

  • Avoid overconsumption, since the effects can increase your heart rate or cause fluctuations in your blood sugar levels, impacting your sleep quality.
  • Try to give your body enough time to process alcohol before going to bed.
  • Avoid consuming caffeine-containing drinks with alcohol, as this can lead to the aggravation of sleep-depriving conditions.
  • Try to drink plenty of water to prevent dehydration, as this can cause headaches and grogginess the following day.

If you typically have trouble sleeping, it’s best to avoid alcohol consumption altogether since it can be particularly disruptive, interfering with your sleep cycle and leading to feelings of grogginess or fatigue the following day.

Alcohol and the Sleep Cycle: What You Need to Know

The human body goes through several stages of sleep over a typical sleep cycle. These stages are necessary for cleaning out harmful organisms and waste products, repairing tissues, building new cells, and consolidating memories. However, alcohol consumption may impact the sleep cycle, specifically stage 3, which is the deep-delta wave sleep, and stage 4, known as the REM (Rapid Eye Movement) sleep. Interruptions at this stage can negatively impact sleep quality, causing a restless night.

Alcohol consumed before bed can make the body fall asleep quickly, but it disrupts the rhythm of the sleep cycle. As a result, the body may take much longer to enter deep-delta wave sleep, leading to increased nocturnal awakenings and tossing and turning during the latter half of the night, which can be very disruptive to the body and mind.

Why Your Nightcap May Not Be Helping You Sleep After All

Although many people reach for a drink before bedtime to help them sleep better, this may do more harm than good. Studies show that while alcohol consumption can have a calming effect initially, it can negatively affect sleep quality when consumed too close to bedtime. Alcohol consumption typically disrupts the natural sleep cycle, leading to a restless night’s rest. This disruption leads to the development of acute sleep deprivation, leading to daytime fatigue and its associated adverse effects on cognitive, academic, and occupational performance.

Alcohol and Insomnia: How Drinking Before Bed Could Be Hurting Your Sleep

If you have insomnia, consuming alcohol before bedtime may worsen your condition. Alcohol has been known to make sleep deprivation and insomnia worse. Although it may help you fall asleep quickly, the quality of your sleep will be poor, and you’ll likely wake up several times in the night. As a result, your body may struggle with the acquisition of specific sleep waves associated with memory consolidation and emotional regulation, eventually leading to the development of long-term behavioral and physiological imbalances.


In summary, the relationship between alcohol and sleep is complicated, and although alcohol may make you sleepy, it can negatively affect the quality and quantity of your sleep. If you’re struggling to get adequate sleep, it’s best to avoid consuming alcohol altogether. However, if you plan to have a drink, limit consumption and give your body enough time to process the alcohol before heading to bed. Ultimately, it’s important to prioritize your sleep and make necessary adjustments to ensure you’re getting the rest you need.
