Men are more likely to suffer from alcoholic insomnia than the fairer sex: 75% versus 60%. In addition, middle-aged people aged 35–44 most often (78%) drink alcohol late at night.
It is believed that alcohol helps to sleep. In fact, according to scientists, its use before bed often leads to negative consequences. So, in the second half of the night, awakenings become more frequent, a person cannot fall asleep again. This is due to a decrease in melatonin production, which leads to a malfunction of the circadian clock that regulates the daily cycle of sleep and wakefulness.
Alcohol also increases the symptoms of obstructive sleep apnea, causes excessive relaxation of the muscles of the throat, neck and head, which leads to respiratory failure, increases the frequency of trips to the toilet, increases the risk of parasomnia and, at a minimum, leads to a feeling of chronic fatigue even immediately after sleep.
