There is a false belief that alcohol helps you sleep better, but the reality is different.


Alcohol, widely consumed in many cultures and social occasions, is often seen as a relaxant that can aid in falling asleep. However, while it's true that alcohol can make individuals feel drowsy and fall asleep faster, its relationship with sleep is more intricate than it appears at first glance.

If alcohol is consumed in the hours before going to bed, the latency period will be reduced, so it will take less time to fall asleep, and during the first part of the night, slow-wave sleep will increase. It may seem that alcohol helps with sleep, but the reality is that in the second half of the night, once the alcohol has been metabolized, sleep will become more superficial, and there will be an increase in awakenings. Therefore, the sleep will not be of good quality.

In addition to the timing of alcohol consumption, the dose will also influence sleep. Generally, the higher the alcohol dose, the greater the negative effects on sleep.

  1. Initial effects of alcohol on sleep: It's true that alcohol can help induce sleep. However, this doesn't mean that the quality of sleep is better. Sleep induced by alcohol tends to be more superficial and less restorative than natural sleep.

  2. Disruption of REM sleep: Sleep consists of several cycles, including the REM (Rapid Eye Movement) stage, which is essential for mental health and memory. Alcohol can suppress REM sleep during the first half of the night, leading to more frequent awakenings during the second half.

  3. Nighttime awakenings: As the sedative effects of alcohol wear off, there's a higher likelihood of experiencing sleep interruptions. This can lead to fragmented sleep and the feeling of not having rested properly.

  4. Long-term effects: Regular consumption of alcohol before sleeping can disrupt the natural balance of sleep, leading to a reliance on alcohol to fall asleep. This can result in insomnia and other sleep issues when trying to sleep without alcohol intake.

  5. Other considerations: Alcohol can exacerbate health issues like sleep apnea and gastroesophageal reflux, both of which can significantly interfere with sleep quality.

In conclusion, although alcohol might seem like a quick solution for falling asleep, its effects on sleep quality and structure can be detrimental in both the short and long term. It's important to consider these factors and opt for healthier and more sustainable means to improve sleep, such as routine, relaxation, and overall health care.

In addition to the time of alcohol intake, the dose will also influence sleep.  Generally, the higher the dose of alcohol, the greater the negative effects on sleep.
