{{TNT|TC1}}

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.{{TNT|TC1}}

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.
