👉 A "nightcap" is a type of meal or snack that is typically consumed before bedtime to help promote relaxation and sleep. Nightcaps are often associated with the concept of "sleeping through the night," as they typically consist of a combination of light snacks, such as fruits, nuts, or crackers, along with alcoholic beverages or coffee. The purpose of these snacks is to provide energy and stimulate the body's natural sleep-wake cycle.
