polyphasés

Polyphasé is a term used to describe a sleep schedule that involves sleeping multiple times throughout a 24-hour period. This contrasts with monophasic sleep, where individuals sleep in one continuous block, typically at night. Polyphasic sleep can take many forms, with schedules varying widely in the number and duration of sleep periods. Some common patterns include the "Everyman" schedule, which features a core sleep period supplemented by shorter naps, and the "Uberman" schedule, which consists of very short, frequent naps distributed throughout the day.

Proponents of polyphasic sleep often claim benefits such as increased alertness, improved cognitive function, and a reduction in total sleep time. However, these claims are not universally supported by scientific evidence. Research into the effects of polyphasic sleep is ongoing, and results can vary significantly depending on the individual and the specific sleep schedule implemented. Potential drawbacks include difficulty adapting to the schedule, social isolation due to non-standard sleep times, and potential health issues if the sleep is not sufficiently restorative. The long-term effects of extreme polyphasic sleep, such as the Uberman schedule, are not well understood and may pose risks. It is generally recommended that individuals consult with a healthcare professional before attempting to significantly alter their sleep patterns.
