The "4-hour rule for sleep" refers to a sleep schedule strategy aimed at achieving approximately four hours of sleep per day through a combination of core sleep and strategically timed naps, as seen in the Everyman sleep schedule.
Understanding the Everyman Sleep Schedule
The Everyman sleep schedule is a polyphasic sleep pattern designed to reduce total sleep time while maintaining functionality. One variation of this schedule aims for approximately four hours of total sleep, achieved by:
- Core Sleep: A single, longer sleep period during the night.
- Naps: Multiple short naps taken throughout the day.
According to one reference, a version of the Everyman sleep schedule includes three hours of sleep during the night combined with three 20-minute naps during the day, totaling about four hours of sleep daily.
