A glass of wine to fall asleep faster? It may make you drowsy, but it does not improve sleep quality. On the contrary.
What research shows
Researchers at the University of Melbourne measured the brain activity of people who had drunk alcohol. Conclusion: alcohol disturbs the frequency of the brain waves that determine deep and light sleep.
How it intervenes
Alcohol stimulates the first deep sleep, but shortens REM sleep. The body needs that dream phase to recover. Whoever drinks within 2 hours before bed disturbs their sleep pattern.
The consequences
The consequences make themselves felt: waking tired, reduced concentration, and in the long term a decline in memory.
The nuance
An occasional glass is no problem. Alcohol as a sleep aid is.
