"Due to alcohol being a depressant substance, this means that it slows down your central nervous system by calming the neurotransmitters that keep you alert. Alcohol can behave the same way sedatives do, by fixating on the two neurotransmitters in your brain known as gamma-aminobutyric acid (GABA) and glutamate."
"The effects of alcohol on the brain also reduce how deeply you go into REM sleep. Since alcohol-induced sleep isn't a true benefit, you might be better off using milk to feel sleepy, instead."
"Generally, dark alcohol can cause one to feel more sleepy. Brandy, cognac, whiskey, and red wine all contain higher levels of compounds that are made during their fermentation process that cause a more profound feeling of sleepiness, compared to drinks like white wine, vodka."
Alcohol acts as a depressant on the central nervous system by targeting neurotransmitters like GABA and glutamate, which maintain alertness. This mechanism slows reaction time, motor functions, and speech while promoting sleep onset. However, alcohol-induced sleep is not truly beneficial because it significantly reduces REM sleep depth, preventing restorative rest. Dark alcohols such as brandy, cognac, whiskey, and red wine contain higher levels of fermentation compounds that produce more pronounced sleepiness compared to lighter spirits like white wine and vodka.
