What is polyphasic sleep?
Polyphasic sleep is a practice based on division of sleep into several smaller blocks per day, as opposed to sleeping in a single nighttime block. Drawing inspiration from the siesta popular in Spain, or from segmented sleep in many cultures before artificial lighting, sleeping polyphasically can reduce the total sleep time required, eliminate chronic tiredness, or help many workers cope with their demanding schedules. Certain principles have been discovered over decades, and these help predict whether a person can adapt if they are disciplined for 1-2 months. 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), while reducing non-essential excess of light sleep.
