Slumbertimes, also known as naptime or siesta, is a period of rest taken during the day to refresh and recharge the body. Other synonyms for slumbertimes include power nap, catnap, snooze, quick rest, doze, and shut-eye. Each of these terms denotes a short and relaxed period of sleep lasting usually less than an hour. Power nap, for instance, indicates the revitalizing and energy-boosting effects of the nap, while catnap implies a short, light sleep often taken in the daytime. Regardless of which term is used, slumbertimes offer a refreshing break from work or daily activities and have been linked to improved productivity and mood.
