Yes, it will, but alcohol will have an influence on the quality of sleep, violating the natural cycles of this process.

Let’s consider some characteristics of normal sleep. A person undergoes two basic states during the sleep process, which have two different types of the brain activity. This is a state of slow and fast sleep. Rapid sleep takes about 25% of the total time, repeats every 90 minutes and lasts from 5 to 30 minutes. It is connected with dreams and is necessary for health, being the most important for the process of restoration of forces.

Alcohol interferes with the normal process of sleep. When a person drinks a large quantity of alcohol before going to bed, he or she can go immediately to the phase of deep sleep, skipping the first stage – the state of drowsiness or fast sleep.

alcohol Alcohol is metabolized at a high enough rate, its concentration in the blood drops to the middle of the night in most people after a few drinks drunk before going to bed, which often leads to withdrawal symptoms. Sleep becomes superficial; there are several awakenings. Thus, alcohol, although effective at the beginning of sleep, worsens it in the second half of the night and reduces the overall process time, leading to daytime sleepiness.

Deep sleep is the phase during which the body is restored, and alcohol interferes with this process. When the effect of alcohol ends, the body goes from the stage of deep sleep into a slumber phase, during which it is much easier to wake up. For this reason, after drinking alcohol, a person often wakes up after several hours of sleep.

Chronic snoring can cause a dangerous violation of the rhythm of breathing and even lead to its stopping – the state of apnea.

Thus, alcohol causes anxious, intermittent and broken sleep.

If you drink alcohol, do not use it immediately before going to bed. Better let your body to have some time for processing. On average, one hour is needed to process one unit of drink. But this can depend on the characteristics of a particular person. If you cannot refuse to drink, it is better to drink two hours before going to bed, as its effect will weaken.
