A single nightcap can help you fall asleep more easily by encouraging an increase in slow-wave sleep – which the body needs in order to repair tissues and strengthen the immune system.
Too much booze, however, interrupts REM sleep, which is vital for memory and concentration. As the alcohol wears off, sleep is often disrupted as you tend to wake up more frequently.
Alcohol also increases heart rate and interferes with the restorative functions of sleep – and the more alcohol you drink, the greater the effect.
