Polyphasic sleeping
Gain extra hours and extra health through the practice of sleeping more than once each day!Polyinfo is dedicated to providing information about sleep and more efficient ways to do it. If you are just starting out, take a look at the Beginners page.
Correction
Until recently, some difficulty assessments have been wrong due to an assumption that vitals cannot be deepened and therefore vital-sleep-requirement was assumed to be consistent across all schedules. This is false.Articles will be updated accordingly until 2025-07-14.
Schedule Navigation
If you are a beginner, please read Beginners to start!- Monophasic: Normal sleep, once a day.
- Biphasic: Biphasic - two sleeps per day.
- MonoCore aka Everyman schedules: One longer core, optionally supported by naps.
- DualCore schedules: Two cores, optionally supported by naps.
- TriCore schedules
- QuadCore schedules
- Coreless schedules (unadvisable)
- Jokes (obviously unadvisable)
Library
Visit the library to see a list of all available snippets!eep.li / eeplink
Almost all links on this website link to eep.li (aka. eeplink). This is our polyphasic URL shortener. You can use it too for quick navigation: For schedules, write eep.li/<schedule name>, and for snippets, write eep.li/!<name>. Schedules are parsed in great detail and unified, so any notation a human can understand will almost certainly work. /m3ext, /m3e, /mex, /monoco3, /everyman-3-extended, etc, all work to redirect you to M3-Extended. To see the interpretation of eep.li, add an ampersand before the schedule name to simply get the expanded and shortened name back. We call links shortened with eeplink, eeplinks.Contributing
