Alcohol and sleep
Leads too much alcohol to sleep problems or take a few glasses of alcohol just for a better night’s sleep? What is the effect of alcohol on your sleep? The views seem to be divided. But scientists at The London Sleep Center in England have for the first time reviewed all major investigations on this issue. With the knowledge of now they conclude the following:
Effects of alcohol on your sleep
Your sleep consists of sleep sleep (REM) and regular, partially deep sleep (NREM). During sleep you run a cycle a number of times. Normally you start sleeping with NREM, followed by a short period of REM sleep, after which you switch back to NREM sleep. Each sleep cycle takes about 90 minutes. All studies on the effects of alcohol on your sleep show that alcohol drops you faster, increases the amount of deep sleep and reduces the amount of sleep.

- At all doses of alcohol you find that you fall asleep faster, so you sleep better in the first half of the night, but you sleep worse in the second half of the night. This may explain why many people who suffer from insomnia tend to grab the bottle if they can not sleep well. But the venom is in the tail. Use of alcohol interferes with the second half of your sleep.
- The majority of the studies indicate when using alcohol on an increase in so-called slow-wave sleep, your deep sleep stages 3 and 4. During slow-wave sleep (SWS), your body regenerates, muscle and bone build up and takes you resistance (immune system). Because alcohol helps to deepen sleep in the first half of the night, sleep problems, sleep apnea, sleep problems, sleep disorders, sleep problems.
- The effects of alcohol on your sleep drop depend on the amount of alcohol you take.The more alcohol you drink the greater the effect of alcohol on your sleep. And because you also take impressions during your REM sleep show that people who have long-term drinking can suffer from memory loss.
- Alcohol slows the onset and reduces the total amount of REM sleep (sleep loss).
Alcohol as self-medication
Delay in the onset of REM sleep often occurs in stressful situations, and there is also a link with depression. Precisely people with depression and anxiety disorders grab the bottle as a form of self-medication. This is because people with depression have too much sleep at the beginning of the night. The use of alcohol reduces this amount of REM sleep. Alcohol then acts as antidepressants.
Alcohol is not a suitable sleeping drug
Alcohol and sleep is therefore not a good combination. By using alcohol you seem to sleep better, but in reality this only applies to the first half of the night. Then you sleep worse. The use of alcohol therefore worsens total sleep. Therefore, alcohol (apart from all other harmful effects) is not suitable for sleeping. In addition, the chance of sleeping , snoring and talking in your sleep is greater if you have drunk a lot.
