Advice From The Scientific Community - Polyphase Sleep
- Feb 20, 2018 -

Studies of brain waves and other physiological indicators show that our biological rhythms are biphasic rather than polyphasic, which determines that our bodies tend to sleep in one lump.  Attempts to reduce the total amount of sleep by taking multiple brief naps can reduce the amount of time spent in different stages of sleep and disrupt biological rhythms, which can eventually lead to negative effects similar to sleep deprivation and sleep rhythm disorders, such as reduced physical and psychological functioning, increased anxiety and tension, and reduced immune function.  Woods naik's blog of people who took part in polyphasic sleep found that most people had to stay awake through a number of " maintenance activities," such as drinking lots of coffee, and that this polyphasic sleep did not show any improvement or improvement in their ability to learn or creativity.


 In some cases, people may not be able to guarantee a full eight-hour sleep.  At this point, regular brief naps may make up for people's lack of sleep.  Dr claudio stampa, a sleep psychologist, conducted a 49 - day study in which a young man took a 30 - minute nap every three hours, adding up to about three hours of sleep a day.  He found that the brain also experiences slow-wave sleep and rapid eye movement sleep in this polyphase sleep, except that the duration of each sleep phase is shortened.  In addition, Stampi published a field study in the journal work and stress that showed that periodic napping can make up for cognitive decline due to sleep deprivation in a state of continuous work that fails to achieve normal full sleep.  However, in his experiments, no matter what the multi-phase sleep strategy also can't let people achieve the same mental state and cognitive performance as normal sleep.


 So, he concluded in why we doze: evolution, chronobiology, polyphasic and ultrashort wave sleep, that when sleep deprivation is inevitable, a short nap of the system can somehow guarantee optimal conditions.  But he does not advocate polyphase sleep as a way of life, because if you want to increase working hours through polyphase sleep, the quality and quantity of sleep is bound to be seriously affected, long-term will only produce similar symptoms of sleep deprivation, also can't improve creativity.
