What is polyphasic sleep?
Polyphasic sleep is a practice that divides sleep into smaller sleep blocks per day, as opposed to having a single nighttime block. Also inspired by 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.¬†
Moreover, we have discovered certain principles over decades. These therefore help predict whether a person can adapt if they are disciplined for at least 1-2 months. Exceptions with long-lasting adaptations DO EXIST, however!
- 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 some non-essential light sleep.
The research on polyphasic sleep is still at a long-lasting yet fledgling stage. However, over the years, we have been able to gather quite a bit of relevant literature on this very unique lifestyle!
