Having an extra sleep is a blessing in disguise for people who yearn for some rest after a long day. However, in some cases, extra sleep can be difficult to achieve, and hence, finding synonyms that could replace the term could be essential. Some of the synonyms for extra sleep could be more nap, additional rest, an extended sleep, more shut-eye, supplemental slumber, and bonus snooze. Regardless of how it is called, catching some extra sleep could boost one's overall mental and physical health and help them wake up feeling energized and refreshed.
