Alcohol may help you fall asleep but it leads to a disrupted night’s rest, report scientists in the UK. Drinking was found to increase tiredness by reducing the length of time in deep sleep, which is important in allowing the body and mind to relax. The higher the consumption of alcohol, the less deep- or rapid eye movement (REM) – sleep takes place. REM is the stage of sleep characterized by rapid saccadic movements of the eyes.
During this stage, the activity of the brain’s neurons is quite similar to that during waking hours and most vividly recalled dream occur during this stage. Most people awakened during REM usually fell alert and refreshed. The UK study found that at all dosages, alcohol brings on sleep quicker, but leads to an increase in sleep disruption in the second half of sleep. Sleep is often deeper to start with, but then it becomes disrupted.
