forty winks
a short, light nap or brief sleep taken to rest and regain energy
The idiom "forty winks" is believed to have originated from the practice of taking a brief, refreshing nap or short sleep during the day. The idea of "forty winks" suggests a short, light slumber that is usually not long enough to be a full sleep cycle but long enough to provide a quick rejuvenation. The phrase has been in use since the 19th century to describe the act of taking a short nap, often to restore one's energy and alertness.
