Alcohol is a common crutch for many people who struggle to sleep. While it may help you fall asleep, alcohol can disrupt your sleep cycle and circadian rhythms, leading to chronic sleep issues such as insomnia. It can also cause night sweats and negatively impact your body's ability to regulate its temperature, which is essential for a good night's rest. Alcohol can lead to more serious sleep disorders and even fatal complications for those with obstructive sleep apnea.

Alcohol can disrupt your sleep cycle and circadian rhythms
Alcohol can also create a tolerance, meaning that you need to drink more to experience alcohol’s effects. This can pave the way to abusive drinking overall. People who rely on alcohol for sleep often complain of sleep deprivation, poor sleep quality, waking often during the night, and feeling sleepy during the day. Each of these complaints is characteristic of insomnia, a condition that, when chronic, can impact your ability to focus on important tasks, dampen your mood, and increase your risk for falls.
Alcohol can also disrupt your sleep by acting as a barrier to losing heat. It leads to poorer sleep, particularly in the second half of the night. This can be made worse by combining alcohol with fatty foods.

Alcohol can cause sleep deprivation, poor sleep quality, and frequent wakings
When you go to bed with alcohol in your system, you're likely to experience more deep sleep and less REM sleep than usual, at least initially. Later in the night, once your body has metabolised the alcohol, you're likely to experience a rise in the lightest stage of sleep, which can lead to frequent wakings and fragmented sleep. Alcohol is also a barrier to losing heat, which can lead to poorer sleep, particularly in the second half of the night.
If you rely on alcohol to fall asleep, you may become dependent on it. This can lead to more serious sleep disorders, such as insomnia, which can impact your ability to focus on important tasks, dampen your mood, and increase your risk for falls.
If you already live with obstructive sleep apnea (OSA), alcohol can cause further complications, including potentially fatal levels of carbon dioxide in your blood.

Alcohol can lead to more serious sleep disorders, such as insomnia
Alcohol can also create a tolerance, meaning that you need to drink more to experience alcohol's effects. This can turn sleep disruptions into a chronic issue. If you go to bed with alcohol in your system, you're likely to experience more deep sleep and less REM sleep than usual, at least initially. Later in the night, once your body has metabolized the alcohol, you're likely to experience a rise in the lightest stage of sleep, which can lead to frequent wakings and fragmented, low-quality sleep.
Many people rely on alcohol's calming effect after a rough day. They may believe it reduces their anxiety over the day's events and helps them get to sleep. If this pattern repeats daily, a person is more likely to become dependent on alcohol to fall asleep.
In order to get a good night's sleep, you need to lose approximately 1°C of body temperature throughout the night. But the alcohol in your system is a barrier to losing heat. It leads to poorer sleep, particularly in the second half of the night. Too much alcohol can be the trigger for waking up bathed in sweat with your pillow soaking wet. Combine alcohol with a fatty meal and your body has its work cut out keeping you cool and keeping you asleep.
Even in moderate amounts, alcohol consumed in the hours before bedtime can cost you sleep and leave you feeling tired the next day.

Alcohol can increase your body temperature, making it harder to sleep
Many people rely on alcohol's calming effects to help them unwind after a stressful day. They may believe it reduces their anxiety and helps them get to sleep. However, if this pattern repeats daily, a person is more likely to become dependent on alcohol to fall asleep. Over time, this can alter the brain chemicals that regulate your sleep cycle and circadian rhythms, sometimes permanently. It can also lead to more serious sleep disorders, such as insomnia.
Ironically, people who rely on alcohol for sleep often complain of sleep deprivation, poor sleep quality, frequent wakings during the night, and daytime sleepiness. Each of these complaints is characteristic of insomnia, a condition that can impact your ability to focus, dampen your mood, and increase your risk of falls.
Additionally, alcohol can disrupt your sleep cycles. When you go to bed with alcohol in your system, you're likely to experience more deep sleep and less REM sleep than usual, at least initially. Later in the night, once your body has metabolised the alcohol, you're likely to experience more light sleep, which can lead to fragmented sleep and frequent wakings.

If you already live with OSA, alcohol can cause further complications, including potentially fatal levels of carbon dioxide in the blood. It's strongly recommended that patients with OSA abstain from all alcohol use. However, it's not easy for people to cut out alcohol completely, especially if they're used to drinking it occasionally. The best thing to do is to avoid consuming alcohol in the hours before bed to minimise its effects.
