What is polyphasic sleep?
Polyphasic sleep is a practice based on division of sleep into smaller sleep blocks per day, as opposed to having a single nighttime block. Drawing inspiration from the Siesta popular in Spain and from segmented sleep in many cultures before artificial lighting, sleeping polyphasically can:
- Reduce the total sleep time required.
- Eliminate chronic tiredness.
- Help many workers cope with their demanding schedules.
- Improve overall sleep quality and quality of life.Â

- Healthy polyphasic sleep retains a scientifically required amount of SWS, or “deep” sleep (e.g. for glymphatic clearing and cell renewal) and REM sleep (e.g. for memory and learning).
- It also reduces non-essential excess of light sleep.
