Everyman 3 или E3 - это оригинальная версия [[Special:MyLanguage/Everyman|Everyman]], предложенная Puredoxyk. Раньше график был известен как единственный Everyman, до того как были добавлены [[Special:MyLanguage/E2|E2]] и [[Special:MyLanguage/E4|E4]]. Следуя схеме именования полифазных расписаний, E3 содержит 1 [[Special:MyLanguage/Cores|ядро]] и 3 [[Special:MyLanguage/naps|нэпа]].<ref name="pd" />


{{TNT|DC1}}
Dual Core 1, ou DC1, é o primeiro cronograma [[Special:MyLanguage/Dual core|Dual Core]], que é o resultado de cortar sono do segundo núcleo do cronograma Segmnentado e a adição de uma soneca durante o dia pra compensar.<ref name="polysoc" /> DC1 também é considerado um cronograma relativamente fácil, e é recomendado pra iniciantes.


== История ==
==Origem==


[[Special:MyLanguage/Puredoxyk|Puredoxyk]] назвала Everyman (теперь E3) менее экстремальной версией [[Special:MyLanguage/Uberman|Uberman]]. E3 был предложен как способ легче адаптироваться к меньшему количеству сна, в то же время будучи более синхронизированным с обычной повседневной жизнью без необходимости чрезмерной строгости графика Uberman.  
DC2 foi originalmente proposta pela [[Special:MyLanguage/Polyphasic Society|Sociedade Polifásica]]. Duas variantes foram propastas, que são detalhadas na seção [[Special:MyLanguage/#original-variants|Variantes originais]]. A comunidade do [[Special:MyLanguage/Polyphasic Sleep Discord|Discord]] depois modificou ligeiramente o cronograma para a sua forma atual.


К 2008 году этот режим стал "запасным вариантом" для людей, проваливших адаптацию к Uberman. Его создание было вдохновлено первой волной попыток адаптироваться к Uberman, которая имела место быть в ранних 2000-х, а затем вновь набрала силу после изнуряющей, но успешной адаптации блоггера личностного роста  [[Special:MyLanguage/Steve Pavlina|Steve Pavlina]] в 2007 году. Он размещал  [https://www.stevepavlina.com/blog/2005/10/polyphasic-sleep/ отчеты о процессе своей адаптации] к Uberman в своем блоге. Частая проблема людей, тогда пытавшихся адаптироваться к Uberman, заключалась в том, что они зачастую проваливались в сон на несколько часов каждые пару дней. В таком случае имело смысл внести эти сбои в режим сна, превратив их тем самым в трехчасовое ядро.
==Mecanismo==


С годами в структуре Е3 произошли изменения. Изначально сделанный Puredoxyk режим содержал ядро, начинающееся около полуночи, что сейчас считается [[Special: MyLanguage / late core | поздним]] для E3 и неоптимальным для получения достаточного количества [[Wikipedia: Slow-wave_sleep | SWS]]. В настоящее время ядро Е3 занимает большую, если не всю часть пика SWS.
{{further|Dual core#Mechanism}}


Е3 был одним из самых популярных графиков из-за значительного сокращения сна по сравнению с монофазным режимом, а также из-за того, что был относительно удобен в повседневной жизни. Несмотря на низкий уровень успеха, популярность E3 до сих пор не утихла.
{{further|Dual core#Alternative mechanism}}
O mecanismo do DC1 é similar ao Segmentado. Cada núcleo é localizado ao redor de cada pico por questão de eficiência. O primeiro núcleo tem aproximadamente a mesma duração do primeiro núcleo do Segmentado, pra preservar a quantidade de [[wikipedia:Slow-wave_sleep|SWS]], enquanto o segundo núcleo é reduzido. Isso permite a redução de sono nesse cronograma.  


Atualmente, a variante recomendada é ter um núcleo de 3h30m e 1h40m respectivamente. A duração do ciclo ser multipla de 100m ao invés de 90m serve pra acomodar ou ciclos de sono mais longos, ou sono [[wikipedia:Rapid_eye_movement_sleep|REM]] extra no começo ou final dos sonos.


== Механизм ==
O cochilo é colocado ao redor da queda do circadiano no começo da tarde. Mas a soneca do DC1 nem sempre é preenchida por sono REM e pode conter principalmente NREM2 pra alguns. Ainda assim, a soneca ajuda a [[Special:MyLanguage/wake time reduction|se manter alerta]] até o primeiro núcleo.


Ядро E3 длится всего 3-3.5 часа (зависит от режима), то есть около двух полных циклов сна. 4 часа ежедневного сна считаются [[Special:MyLanguage/Scheduling overview#Minimum sleep threshold|абсолютным минимумом]], необходимым большинству людей для удовлетворения  потребности в 90 минут [[wikipedia: Rapid_eye_movement_sleep | REM]], 90 минут SWS и достаточном количества переходного легкого сна.  
DC1 costuma ser comparado com o [[Special:MyLanguage/E2|E2]], já que ambos os cronogramas tem sonos colocas em lugares similares durante o dia. Eles tem uma quantidade similar de sono total e o mesmo número de blocos de sono totais (3) por dia, com a principal diferença sendo que E2 tem uma soneca ao invés de um núcleo durante o nascer do sol.


Самый важный совет по составлению своей вариации режима Е3 - расположить ядро так, чтобы оно покрывало пик SWS, начинаясь с 21-22 по местному времени. Дальнейшая ротация расписания крайне сложна и требует строгого [[Special: MyLanguage / управление циркадными ритмами | регулирования циркадного ритма]]. В идеальном варианте Е3 ядром должны быть покрыта вся потребность в SWS, а также некоторая часть потребности в REM.
==Adaptação==


Из-за сокращенного общего времени сна каждый нэп не будет [[Special:MyLanguage/wake time reduction|поддерживать бодрствование]] в течение такого же длительного периода времени, как на Е2 или одном из расширенных графиков с общим временем сна, большим, чем предполагает Е3. Идеальные промежутки между снами составляют 3-4 часа между ядром и первым нэпом, 4-5 часа между первым и вторым нэпами, и по 6-7 часов для последних двух промежутков. При успешной адаптации первые два нэпа содержат REM, а третий - в основном легкий сон.
Adaptação ao DC1 costuma ser feito com [[Special:MyLanguage/cold turkey|Adaptação abrupta]]. Alternativamente, também é possível se adaptar a esse cronograma [[Special:MyLanguage/gradual adaptation|gradualmente]] se adaptando primeiramente ao sono Segmentado.  


=== Adaptação abrupta ===


== Адаптация ==
Já que o núcleo de ~3,5 horas pode não cobrir todo o sono SWS necessário do começo, dividir o sono SWS pode ser necessário, o que pode fazer alguém acordar no meio do sono SWS em qualquer um dos núcleos. Altos requisitos de sono SWS (pelo menos 150m) vão provavelmente entender o primeiro núcleo (para ~4,5h) pra cobrir todo o sono SWS necessário.


Е3 - это режим с наименьшим количеством сна из тех, к которым, как считается, может адаптироваться человек со средними потребностями во сне. Жесткое ограничение по времени для REM и SWS делает адаптацию чрезвычайно сложной.
===Adaptação gradual===


На [[Special: MyLanguage / monophasic | монофазном]] сне SWS распространяется вплоть до третьего цикла сна или даже дольше. Поэтому когда ядро внезапно обрывается, в нем могут участиться SWS-пробуждения, что зачастую приводит к провалу адаптации. Хуже того, дневной сон может также содержать SWS по мере развития адаптации, что может привести к тяжелым пробужениям и большему количеству потенциальных просыпов.  
Esse método tende a ser mais lento do que a adaptação abrupta, mas a transição foi feita pra ser menos estressante de Segmentado para DC1. No entanto, não existe sucesso garantido para o DC1, e esse método na verdade tem tido uma taxa de sucesso menor do que a adaptação abrupta. Esse é principalmente devido a grande quantidade de tempo que levaria pra ter bons resultados em 2 adaptações seguidas.  


Недели постоянства в режиме необходимы для того, чтобы в конечном итоге достичь такого распределения стадий сна, что дневной сон будет содержать REM и NREM 1-2, а ядро - вмещать все необходимое SWS. Размещение первых нэпов в пике REM способствует этому распределению.  
No entanto, pra pessoas que se adaptaram ao sono Segmentado e se mantiveram nele por um bom tempo, a transição para o DC1 tem a mesma dificuldade.  


==Dificuldade==


=== Постепенная адаптация ===
DC1 é um cronograma de dificuldade moderada. Pra quem tem naturalmente o sono segmentado, é provavelmente mais fácil e mais natural do que o E2. No entanto, para outros, o E2 seria muito mais fácil, já que não requer que o sono SWS seja dividido. DC1 é conhecido por ser menos flexível se comparado ao E2, e assim como todos os outros cronogramas DC2, ele é muito menos tolerante para núcleos atrasados.


На Е3 возможно перейти с [[Special:MyLanguage/E1|E1]], [[Special:MyLanguage/E2|E2]] или [[Special:MyLanguage/#extended|E3-extended]] путем сокращения ядра и/или добавления нэпов. Впрочем, стоит учитывать, что очень немногие смогли перейти на Е3 с Е2 и успешно адаптироваться. Такой метод адаптации зачастую занимает слишком много времени, поскольку [[wikipedia: Sleep_deprivation | депривация сна]] может растянуться на период вплоть до нескольких месяцев.
==Considerações de Estilo de Vida==


Assim como cronogramas Dual Core, a primeiro núcleo precisa ser colocado nas primeiras horas da noite pra cobrir o pico SWS. Atividades da noite que forçam o primeiro núcleo a ser adiado vão danificar o cronograma. Enquanto é possível se recuperar de tais eventos ocasionalmente depois da adaptação, ainda prejudica muito a adaptação, e pode eventualmente fazer o cronograma fracassar.


=== Прямая адаптация ===
Os horário mais longo entre núcleos também pode não ser pra todo mundo já que ficar acordado por várias horas toda noite pode ser chato e eventualmente ser demais pra aguentar.


Большинство успешных адаптаций к Е3 происходит по методу [[Special:MyLanguage/cold turkey|прямой адаптации]]. Время, необходимое для адаптации к Е3 с помощью этого метода, потенциально меньше, чем при использовании [[Special: MyLanguage / постепенной адаптации | постепенной адаптации]], однако она проходит намного тяжелее по сравнению с прямой адаптацией к Е2/Е1, и неудача из-за пропуска нэпов, смещения нэпов, смещения ядра и/или неправильной оценки собственных потребностей на сне может привести к задержке в [[Special:MyLanguage/4-Stages Adaptation Model#Stage 3|стадии 3]] на длительный промежуток времени.  
Não são muitos no cronograma DC1 (não estendido) que são capazes de ajustar os núcleos significativamente. Seria necessário reduzir os requisitos totais de sono, ou ter experiência com sono polifásico pra gerenciar um DC1 flexível. Com o segundo núcleo fixo, o primeiro núcleo pode ser movido uma hora para trás ou para frente. Não há certeza sobre quão flexível a soneca pode ser. De qualquer forma, mais dados são necessários pra determinar a flexibilidade do DC1 em comparação ao E2, cuja segunda soneca é altamente flexível.  


Tendo apenas uma soneca diurna, o DC1 é apropriado para trabalhos que permitem que uma soneca seja feita durante o intervalo.


=== Naptation ===
Com apenas 2 ciclos SWS no núcleo com a variante principal, pode não ser possível acomodar as necessidades extras de sono SWS vindas de exercícios intensos.


Когда-то Naptation был популярным способом начать адаптацию к Е3, но теперь его не рекомендуют использовать. Основная причина заключается в том, что если начинать адаптацию, будучи в состоянии [[Special:MyLanguage/sleep debt|депривации сна]], то это может привести к скорым пересыпам, так как увеличивает сложность адаптации. Перед началом адаптации рекомендуется [[Special: MyLanguage / recovery | избавиться от долга сна]], чтобы избежать этого. Для Е3 укороченное ядро приводит к быстрому накоплению [[wikipedia: Sleep_deprivation | депривации сна]]. Научиться засыпать в нэп при таких условиях относительно просто, что делает метод Naptation в значительной степени ненужным.
== Variantes ==


O DC1 oferece várias opções de cronograma, mas as únicas variantes com taxas de sucesso significativo são as variantes originais ou estendidas.


=== Обратная постепенная адаптация ===
===Variantes originais===
 
[[Special: MyLanguage / обратная постепенная адаптация | Обратная постепенная адаптация]] также когда-то была популярным способом перейти на Е3. Стратегия состоит в том, чтобы сначала придерживаться режима Uberman, а через несколько дней на нем перейти к Е3, пользуясь большим давлением сна. Ожидая скорого просыпа на Uberman, можно выбрать один из его нэпов (обычно в вечерние часы), чтобы сделать ядром Е3 с продолжительностью по выбору (3 или 3.5 часа). Хотя в последнее время этот метод не приветствуется, он действительно имел некоторый успех за долгую историю адаптаций к Е3.
 
Как и в случае с Naptation, переход на Е3 с уже существующим недосыпом от Uberman не рекомендуется, так как в теории только усложнит/затянет адаптацию. [[Special: MyLanguage / recovery | Период восстановления]] на монофазном сне после того, как вы научитесь нэпам на Uberman, предпочтительнее прямого перехода на Е3. Организму тоже нужно время, чтобы полностью сменить режим, а быстрое изменение в паттернах сна серьезно нарушит этот процесс.
 
 
== Сложность ==
 
Е3 вмещает в себя примерно 4-4.5 часа сна в день, поэтому считается одним из самых сложных графиков, к которым может адаптироваться взрослый человек со средними потребностями во сне. Даже после адаптации большинство людей сообщали об относительно небольшой [[Special: MyLanguage / flexing | гибкости]] времени нэпов и ядра по сравнению с [[Special: MyLanguage / # extended | расширенной версией]] или [[Special: MyLanguage / E2 | E2]].
 
 
== Образ жизни ==
 
Е3 - относительно удобный режим для многих людей, так как содержит только три нэпа и короткое ядро. Он хорошо подходит людям с гибким рабочим графиком или тем, кто работает удаленно. По сравнению с расписаниями, предполагающими дневное ядро, планирование дневного нэпа на Е3 также не представляет особой трудности.


<div lang="en" dir="ltr" class="mw-content-ltr">
<div lang="en" dir="ltr" class="mw-content-ltr">
While the default variant usually has little flexibility, the 3.5h core variant has seen more success in flexing. Nap 2 and 3 can be somewhat flexible (<1h forward or back) , and the core to a smaller extent (<30m).

These are the versions originally proposed by Polyphasic Society. Both of these give a total of 5h in core sleep.

== Variants ==
The first (outer) variant has the same first core as Segmented, and may allow for a smoother transition from it. It closely resembles the current default version, and most of what is said about the standard one also applies to it.
</div>
</div>


<div lang="en" dir="ltr" class="mw-content-ltr">
<div lang="en" dir="ltr" class="mw-content-ltr">
As a popular schedule with a long history, several variants have been proposed, with some having seen success.
The second (inner) one is more balanced in terms SWS and REM potential, and may allow for a more complete repartitioning. However, 2.5-hour cores increase the likelihood for SWS wakes, which increases the chance for oversleeping, especially in the first core. For some, waking up from SWS and/or REM is extremely challenging and best avoided. This variant may be better for those needing more REM than SWS. Adapting to this variant may eventually result in 4 sleep cycles of ~75 minutes. However, this is mostly hypothetical and requires more data to confirm.

[[File:E3 Midnight Core.png|thumb|E3 proposed by Puredoxyk|alt=]]
[[File:DC1-mod.png|thumb|Slightly shortened/extended cores]]
This version was the one originally proposed by Puredoxyk. The core is placed late, after much of the SWS peak has passed. This variant is much more social life-friendly compared to the default.
A slightly longer second core can account for a higher REM need. The higher total sleep also increases the potential to flex the cores after adaptation. This variant is considered viable, though the second core may or may not cause difficult wakes.
</div>  
</div>  


<div lang="en" dir="ltr" class="mw-content-ltr">
<div lang="en" dir="ltr" class="mw-content-ltr">
The first nap is taken before the work day starts and functions like the first nap on [[Special:MyLanguage/E2|E2]], with the other 2 naps placed during the day. This scheduling resembles [[Special:MyLanguage/DC2|DC2]] whose naps are placed at similar hours. There is also a choice of scheduling a 3.5h core for a slightly easier adaptation.
Using slightly shortened cores would be more difficult, as it has less total sleep time. Repartitioning of sleep stages will need to be more intense than on the standard version. This may be suitable for those with slightly lower monophasic needs (~7h). It is unknown how flexible the variant would be after adapting, since there are no records of its flexibility, and the successful adaptees did not maintain the schedule long enough.
</div>  
</div>  


<div lang="en" dir="ltr" class="mw-content-ltr">
<div lang="en" dir="ltr" class="mw-content-ltr">
However, this variant has seen a lower success rate compared to the default one. This is largely attributed to the difficulty gaining enough SWS, with SWS possibly seeping into the last nap, causing some extremely difficult wakes in adaptation. Individuals with lower SWS requirements might find this variant more tolerable.

[[File:E3 Dawn Core.png|thumb|An extreme E3 with a dawn core|alt=]]
Puredoxyk also adapted to this E3 variant at one point. However, she was also adapted to Uberman before, and her sleep requirements are likely very low. The core around sunrise hours will likely contain relatively little SWS. Alternatively, extreme [[Special:MyLanguage/circadian management|circadian management]] will be required to maintain SWS. It is doubtful whether a sleeper with normal SWS requirements would be able to adapt to this E3, as there has been very few successful adaptations. The rotation of the naps also moves the last nap into SWS peak hours, which can be extremely difficult to wake from. This variant should be avoided by most people.

[[File:Slightly longer core.png|thumb|E3 with a 3.5h core|alt=]]
[[File:DC1-30m.png|thumb|30min naps and shortened cores]]
The same principles that apply to the 3h core also apply to a 3.5h core. The core sleep still should start by 22-23 to retain a sufficient amount of SWS. If all SWS has been accounted for, the additional 30 minutes will provide REM and/or light sleep, which may help with either gaining enough REM or sustaining wakefulness. This is also a core duration that is popularly used in [[Special:MyLanguage/Segmented|Segmented]] sleep and scheduled in the SWS peak for the same purpose. The naps should be placed in the same way as the standard schedule.
These variants are derived from [[Special:MyLanguage/Triphasic|Triphasic]], and have significantly less total sleep than standard DC1. They extend the night and morning cores, while shortening the daytime core of Triphasic to a 30m nap for ease of scheduling. Both attempts and adaptations have been rare, possibly because of the uncommon core lengths leading to difficult wakes.
</div>
 
<div lang="en" dir="ltr" class="mw-content-ltr">
The benefits of this variant is the flexibility of the naps and cores. Out of all polyphasic schedules with 4-4.5h total sleep ("Hard" and "Very Hard" category), this schedule is the most flexible.
</div>  
</div>  


<div lang="en" dir="ltr" class="mw-content-ltr">
<div lang="en" dir="ltr" class="mw-content-ltr">
However, adaptation remains difficult, and the exhausting process of repartitioning will cover the second or third week. Beginners aiming for this variant should start at a safer amount of total sleep, such as with [[Special:MyLanguage/E2|E2]] or the [[Special:MyLanguage/#extended|extended]] variant.
Note that these two variants are likely to be much more difficult than standard DC1 ("Hard" or "Very Hard" category), perhaps similar to Triphasic.

<div lang="en" dir="ltr" class="mw-content-ltr">
<div lang="en" dir="ltr" class="mw-content-ltr">
The extended version (often known as E3E), with one extra sleep cycle (90m) added, has seen much success. Today in the [[Special:MyLanguage/Polyphasic Sleep Discord|Discord]], it is one of the most commonly attempted schedules, for the balance of wake time and flexibility it provides.
[[File:DC1-ext.png|thumb|Two possible ways to extend DC1]]
</div>  
Both of these variants over the years have reported a lot of success. They are more beginner-friendly, but offer less sleep reduction. Those with a higher monophasic baseline (~9h) are also recommended to attempt these variants.
</div>


<div lang="en" dir="ltr" class="mw-content-ltr">
<div lang="en" dir="ltr" class="mw-content-ltr">
The ideal scheduling of E3-extended would have a naps in the early morning, noon/early afternoon and late afternoon. The wake gap after core can be between 3 and 4.5 hours, similar to E2. The last nap can be as late as ~18 as long as all SWS is accounted by the core.
The choice between the two depends on the balance of SWS and REM requirements. The 3-3 variant would favour more balanced or higher REM needs, whereas the 4.5-1.5 favours higher SWS needs, such as with those who regularly perform intense exercise. Both variants allow a somewhat later first core (up to ~23) compared to the default variant.
</div>  
</div>  


<div lang="en" dir="ltr" class="mw-content-ltr">
<div lang="en" dir="ltr" class="mw-content-ltr">
Compared to regular or 3.5h core E3, the extended variant leaves time for extra SWS incurred by heavy exercise, and is less likely to hinder muscle building and growth. The adaptation process is also much more forgiving than the regular variant, as it has a much higher total sleep time. The extended core would often allow all SWS to remain intact during adaptation, thus preventing much SWS from seeping into naps or the end of the core. This makes adaptation to this much easier than to regular E3.
These variants also allow a long morning wake gap, up to ~8-9 hours. As it has a higher total sleep time, maintaining alertness is much easier than on regular DC1. This may allow one to stay awake through the workday, and then have a nap after work (at ~16-17). These are also known to be much more flexible, both in the cores and in the nap. After adapting, one can also proceed to [[Special:MyLanguage/DC2|DC2]] to as a route to adapt to [[Special:MyLanguage/Ducamayl|Ducamayl]].
</div>  
</div>  


<div lang="en" dir="ltr" class="mw-content-ltr">
<div lang="en" dir="ltr" class="mw-content-ltr">
Compared to E2, the extra nap allows for more flexibility in nap timings, and reduces the difficulty. The overall sleep pressure on this schedule is much lower than on E3 and slightly lower than on E2. This also means the [[wikipedia:Sleep_deprivation|sleep deprivation]] incurred by skipping a nap is much lower than on E2.

<div lang="en" dir="ltr" class="mw-content-ltr">
==== Pronap ====
[[File:DC1 Long Morning Gap.png|thumb|A DC1 variant with 8h morning wake gap|alt=]]
On this variant, the core gap is shortened and the core-nap gap is lengthened. This may be easier to schedule for some. However, this has been very difficult, and has essentially few successful adaptations. Individuals with slightly lower sleep needs may be more able to do this, as they can stay awake longer at a given total sleep time.

<div lang="en" dir="ltr" class="mw-content-ltr">
[[File:E3-extended with Pronap.png|thumb|E3-extended with a Pronap|alt=]]
Similar to E2, the morning gap is suggested to be no longer than 7-8 hours. The evening gap can be up to about 9 hours, because sleep pressure is lower then.
As SWS is most likely covered by the core, a pronap is plausible for this schedule. This has rarely been attempted, though, as E3-extended already has a relatively high total sleep.
</div>
</div>  


<div lang="en" dir="ltr" class="mw-content-ltr">
<div lang="en" dir="ltr" class="mw-content-ltr">
Note that pronaps on regular E3 is not recommended, as the 3 or 3.5h cores may not cover all SWS needs when adaptation first begins.

The 5h core idea from E2 can also be applied to E3-extended. With the total sleep of 6h and a high frequency of sleep, this variant should suit people with high monophasic requirements (~9-9.5h). This one has also not seen many attempts, though.
Some individuals find that a nap around REM peak results in more vivid dream recall compared to a core. This variant makes use of a dawn nap, moving the second core to a position similar to [[Special:MyLanguage/Siesta|Siesta]]. Attempts are very rare, and only one person is known to have successfully adapted to it.

DC1
Dual Core 1
chart link

Total sleep5 hours 20 minutes
Proposed byPolyphasic Society
DifficultyModerate
Specification2 core sleeps, 1 nap

Dual Core 1, ou DC1, é o primeiro cronograma Dual Core, que é o resultado de cortar sono do segundo núcleo do cronograma Segmnentado e a adição de uma soneca durante o dia pra compensar.[1] DC1 também é considerado um cronograma relativamente fácil, e é recomendado pra iniciantes.

Origem

DC2 foi originalmente proposta pela Sociedade Polifásica. Duas variantes foram propastas, que são detalhadas na seção Variantes originais. A comunidade do Discord depois modificou ligeiramente o cronograma para a sua forma atual.

Mecanismo

O mecanismo do DC1 é similar ao Segmentado. Cada núcleo é localizado ao redor de cada pico por questão de eficiência. O primeiro núcleo tem aproximadamente a mesma duração do primeiro núcleo do Segmentado, pra preservar a quantidade de SWS, enquanto o segundo núcleo é reduzido. Isso permite a redução de sono nesse cronograma.

Atualmente, a variante recomendada é ter um núcleo de 3h30m e 1h40m respectivamente. A duração do ciclo ser multipla de 100m ao invés de 90m serve pra acomodar ou ciclos de sono mais longos, ou sono REM extra no começo ou final dos sonos.

O cochilo é colocado ao redor da queda do circadiano no começo da tarde. Mas a soneca do DC1 nem sempre é preenchida por sono REM e pode conter principalmente NREM2 pra alguns. Ainda assim, a soneca ajuda a se manter alerta até o primeiro núcleo.

DC1 costuma ser comparado com o E2, já que ambos os cronogramas tem sonos colocas em lugares similares durante o dia. Eles tem uma quantidade similar de sono total e o mesmo número de blocos de sono totais (3) por dia, com a principal diferença sendo que E2 tem uma soneca ao invés de um núcleo durante o nascer do sol.

Adaptação

Adaptação ao DC1 costuma ser feito com Adaptação abrupta. Alternativamente, também é possível se adaptar a esse cronograma gradualmente se adaptando primeiramente ao sono Segmentado.

Adaptação abrupta

Já que o núcleo de ~3,5 horas pode não cobrir todo o sono SWS necessário do começo, dividir o sono SWS pode ser necessário, o que pode fazer alguém acordar no meio do sono SWS em qualquer um dos núcleos. Altos requisitos de sono SWS (pelo menos 150m) vão provavelmente entender o primeiro núcleo (para ~4,5h) pra cobrir todo o sono SWS necessário.

Adaptação gradual

Esse método tende a ser mais lento do que a adaptação abrupta, mas a transição foi feita pra ser menos estressante de Segmentado para DC1. No entanto, não existe sucesso garantido para o DC1, e esse método na verdade tem tido uma taxa de sucesso menor do que a adaptação abrupta. Esse é principalmente devido a grande quantidade de tempo que levaria pra ter bons resultados em 2 adaptações seguidas.

No entanto, pra pessoas que se adaptaram ao sono Segmentado e se mantiveram nele por um bom tempo, a transição para o DC1 tem a mesma dificuldade.

Dificuldade

DC1 é um cronograma de dificuldade moderada. Pra quem tem naturalmente o sono segmentado, é provavelmente mais fácil e mais natural do que o E2. No entanto, para outros, o E2 seria muito mais fácil, já que não requer que o sono SWS seja dividido. DC1 é conhecido por ser menos flexível se comparado ao E2, e assim como todos os outros cronogramas DC2, ele é muito menos tolerante para núcleos atrasados.

Considerações de Estilo de Vida

Assim como cronogramas Dual Core, a primeiro núcleo precisa ser colocado nas primeiras horas da noite pra cobrir o pico SWS. Atividades da noite que forçam o primeiro núcleo a ser adiado vão danificar o cronograma. Enquanto é possível se recuperar de tais eventos ocasionalmente depois da adaptação, ainda prejudica muito a adaptação, e pode eventualmente fazer o cronograma fracassar.

Os horário mais longo entre núcleos também pode não ser pra todo mundo já que ficar acordado por várias horas toda noite pode ser chato e eventualmente ser demais pra aguentar.

Não são muitos no cronograma DC1 (não estendido) que são capazes de ajustar os núcleos significativamente. Seria necessário reduzir os requisitos totais de sono, ou ter experiência com sono polifásico pra gerenciar um DC1 flexível. Com o segundo núcleo fixo, o primeiro núcleo pode ser movido uma hora para trás ou para frente. Não há certeza sobre quão flexível a soneca pode ser. De qualquer forma, mais dados são necessários pra determinar a flexibilidade do DC1 em comparação ao E2, cuja segunda soneca é altamente flexível.

Tendo apenas uma soneca diurna, o DC1 é apropriado para trabalhos que permitem que uma soneca seja feita durante o intervalo.

Com apenas 2 ciclos SWS no núcleo com a variante principal, pode não ser possível acomodar as necessidades extras de sono SWS vindas de exercícios intensos.

Variantes

O DC1 oferece várias opções de cronograma, mas as únicas variantes com taxas de sucesso significativo são as variantes originais ou estendidas.

Variantes originais

Original DC1 variants

These are the versions originally proposed by Polyphasic Society. Both of these give a total of 5h in core sleep.

The first (outer) variant has the same first core as Segmented, and may allow for a smoother transition from it. It closely resembles the current default version, and most of what is said about the standard one also applies to it.

The second (inner) one is more balanced in terms SWS and REM potential, and may allow for a more complete repartitioning. However, 2.5-hour cores increase the likelihood for SWS wakes, which increases the chance for oversleeping, especially in the first core. For some, waking up from SWS and/or REM is extremely challenging and best avoided. This variant may be better for those needing more REM than SWS. Adapting to this variant may eventually result in 4 sleep cycles of ~75 minutes. However, this is mostly hypothetical and requires more data to confirm.

Slightly modified core duration

Slightly shortened/extended cores

A slightly longer second core can account for a higher REM need. The higher total sleep also increases the potential to flex the cores after adaptation. This variant is considered viable, though the second core may or may not cause difficult wakes.

Using slightly shortened cores would be more difficult, as it has less total sleep time. Repartitioning of sleep stages will need to be more intense than on the standard version. This may be suitable for those with slightly lower monophasic needs (~7h). It is unknown how flexible the variant would be after adapting, since there are no records of its flexibility, and the successful adaptees did not maintain the schedule long enough.

Shortened cores and 30-minute naps

30min naps and shortened cores

These variants are derived from Triphasic, and have significantly less total sleep than standard DC1. They extend the night and morning cores, while shortening the daytime core of Triphasic to a 30m nap for ease of scheduling. Both attempts and adaptations have been rare, possibly because of the uncommon core lengths leading to difficult wakes.

Note that these two variants are likely to be much more difficult than standard DC1 ("Hard" or "Very Hard" category), perhaps similar to Triphasic.

Extended

Two possible ways to extend DC1

Both of these variants over the years have reported a lot of success. They are more beginner-friendly, but offer less sleep reduction. Those with a higher monophasic baseline (~9h) are also recommended to attempt these variants.

The choice between the two depends on the balance of SWS and REM requirements. The 3-3 variant would favour more balanced or higher REM needs, whereas the 4.5-1.5 favours higher SWS needs, such as with those who regularly perform intense exercise. Both variants allow a somewhat later first core (up to ~23) compared to the default variant.

These variants also allow a long morning wake gap, up to ~8-9 hours. As it has a higher total sleep time, maintaining alertness is much easier than on regular DC1. This may allow one to stay awake through the workday, and then have a nap after work (at ~16-17). These are also known to be much more flexible, both in the cores and in the nap. After adapting, one can also proceed to DC2 to as a route to adapt to Ducamayl.

Longer post-core gap

On this variant, the core gap is shortened and the core-nap gap is lengthened. This may be easier to schedule for some. However, this has been very difficult, and has essentially few successful adaptations. Individuals with slightly lower sleep needs may be more able to do this, as they can stay awake longer at a given total sleep time.

Similar to E2, the morning gap is suggested to be no longer than 7-8 hours. The evening gap can be up to about 9 hours, because sleep pressure is lower then.

Core-nap flip

Some individuals find that a nap around REM peak results in more vivid dream recall compared to a core. This variant makes use of a dawn nap, moving the second core to a position similar to Siesta. Attempts are very rare, and only one person is known to have successfully adapted to it.
