Tri Core 1, or TC1, is one of the newer version of Triphasic sleep and was created in 2017 with the goal to neutralize the inconvenient daytime core on Triphasic sleep. On TC1, all core sleeps are moved to the night hours since sleep pressure at night is often higher than in the day, and the short daytime nap resembles a short siesta, filling up alertness level with a long daytime wake gap from the third to the first core. There have been few successes on TC1 than on Triphasic because of TC1's somewhat inconvenient structure of night sleep.

All of the three cores on this schedule are placed during the night and morning hours, with a nap inserted in the day to maintain alertness. The first core and the last core are likely to primarily contain [[SWS]] and [[REM]] sleep, whereas the middle core is likely to contain mixed stages. The wake gap between the cores should be at least 2h to facilitate falling asleep in each core and avoid interrupted sleep.  
  
The main difference between Triphasic and TC1 is the addition of a daytime nap and a core that is placed in the middle of the other 2 cores located at SWS and REM peak respectively. As a result, the adaptation to TC1 will be different than to Triphasic. Initially, it will be difficult to fall asleep in the core sleeps because they are placed close to each other. SWS will start to get into the core sleeps, resulting in a slowly building REM debt. However, because there are 3 core sleeps around night hours, staying awake until the next core sleep is deemed easier than on Triphasic when adapting. Each of these core sleeps also gives a different distribution of vital sleep stages - the first core will be very dense with SWS, the second core will be mixed between SWS and some amount of REM sleep and the third core will heavily favor REM sleep. The wake gap between each core should be '''at least 2h''' to facilitate falling asleep in each core to avoid interrupted sleep.

The daytime nap alleviates homeostatic pressure by providing a chance to get more REM sleep, and sustains alertness until the SWS core. However, the repartitioning process on TC1 is no less than, if not more difficult, than on Triphasic, due to the ease for oversleeping in any of the core sleeps when adapting.

The defining distinction between Triphasic and TC1 is that the night gap is a lot more packed on TC1 with the core sleeps. This can create an impression that TC1 divides the day into several small parts with each core giving more and more compressed vital sleep stages. However, because the wake gap at night is shorter on TC1 than on Triphasic, physically lighter and more peaceful activities are preferred on TC1 (e.g, studying, cooking, planning, chores) to assist in falling asleep in the cores. However, to many individuals, it may be very inconvenient to schedule 3 core sleeps at night, when all of them are placed close to one another. Strenuous exercising may also be overbearing for the total sleep of less than 5 hours. It is also very unlikely TC1 will become very flexible after the adaptation, also because of its total sleep. Slightly flexing a core sleep or two, and/or the nap is acceptable, but so far no one has demonstrated how flexible TC1 can be, assuming a normal sleep requirement.

Compared to Triphasic, it is much easier to schedule TC1, as it does not have the daytime core. However, the shorter gaps may be more limitng in terms of activities. For example, more mentally stimulating activities may not be advisable to avoid difficulties with falling asleep.
  
It is also possible to extend one TC1's core by an extra 90m cycle, but so far no one has adapted to this extended variant either, and it is largely outclassed by Triphasic-extended in scheduling convenience and viability. However, TC1 still offers a large amount of sleep reduction (with a difficult adaptation) and can be a fitting choice for those who love Triphasic, or the idea of having 3 core sleeps, but cannot afford any core sleeps during the day.

TC1 is likely to be slightly flexible after adaptation. Slightly flexing any one of the cores and/or the nap may be plausible, but so far no one has demonstrated this.

Tri Core 1, or TC1, is a schedule with 3 single cycle cores and 1 nap, as a part of the Tri core schedule family.[1]

Origin

TC1 was created in 2017 by Discord user LichTerLoh with the goal to avoid the inconvenient daytime core on Triphasic.

Mechanism

All of the three cores on this schedule are placed during the night and morning hours, with a nap inserted in the day to maintain alertness. The first core and the last core are likely to primarily contain SWS and REM sleep, whereas the middle core is likely to contain mixed stages. The wake gap between the cores should be at least 2h to facilitate falling asleep in each core and avoid interrupted sleep.

Adaptation

Initially, it will be difficult to fall asleep in the core sleeps because they are placed close to each other. However, because there are 3 core sleeps around night hours, staying awake at night should be easier compared to Triphasic when adapting. However, compared to the daytime core in Triphasic, the night core in TC1 is likely to be more difficult to wake up from.

After adapting to TC1, one may slowly transition to DC3 by turning the third core into a nap and adding a third nap in the afternoon.

Difficulty

Little is known about the difficulty of this schedule, as there has been few attempts and only a few successes. It is likely to be more difficult than schedules with similar totals such as E2 and DC1, as the lack of a long core sleep necessitates the splitting of SWS, which can cause extremely difficult wakes.

Lifestyle considerations

Compared to Triphasic, it is much easier to schedule TC1, as it does not have the daytime core. However, the shorter gaps may be more limitng in terms of activities. For example, more mentally stimulating activities may not be advisable to avoid difficulties with falling asleep.

TC1 is likely to be slightly flexible after adaptation. Slightly flexing any one of the cores and/or the nap may be plausible, but so far no one has demonstrated this. TC1 provides a relatively large sleep reduction, and can be chosen by those who like the idea of having many short cores. However, DC1 and DC2 are more commonly attempted, and are likely easier to adapt to.

Variants

It is also possible to extend one TC1's core by an extra 90 m cycle, but so far few have attempted and no one has adapted to it. Either Triphasic-ext or one of the extended Dual core schedules would be preferable, as they avoid the short gaps that may make it difficult to fall asleep.
