What is a nightcap?

A nightcap is an alcoholic drink taken before bed, typically to induce sleep or relaxation. Nightcaps are often consumed in the evening, after dinner or before bedtime. Common nightcap choices include beer, wine, spirits, and liqueurs. Some people believe that a nightcap can help them fall asleep more easily, while others find that it can disrupt sleep quality. There is some evidence to suggest that alcohol can interfere with certain stages of sleep, including REM sleep, which is important for memory consolidation and emotional regulation. However, the effects of alcohol on sleep can vary from person to person. Ultimately, the decision to consume a nightcap is a personal one.
