Tri Core 1, or TC1, is a Triphasic schedule with 3 single cycle cores and 1 nap during the day time. On TC1, all core sleeps from Triphasic 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 the alertness level with a long daytime wake gap from the third to the first [[Cores|core]].<ref>[https://www.polyphasic.net/schedules/tri-core/ polyphasic.net].

== Mechanism ==

The main difference between Triphasic and TC1 is the addition of a daytime [[Naps|nap]] and a core that is placed in the middle of the other 2 cores located at [[SWS]] and [[REM]] peak respectively.  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.

== Lifestyle considerations ==

== 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.

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.
