A "cat nap" is a short period of sleep, usually taken during the day, that lasts no more than 10-30 minutes. While the term "cat nap" is widely used and recognized, there are several other ways to describe this brief moment of rest. Some synonyms for "cat nap" include power nap, snooze, doze, shut-eye, siesta, and micro nap. These words can be used interchangeably to describe a quick rest that provides energy and rejuvenation. Whether you call it a catnap or a power nap, taking a short rest during the day can lead to increased productivity and improved overall health.
