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
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, for 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. 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.
Variants
It is also possible to extend one TC1's core by an extra 90 m 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.
