Changes

There are, however, a lot of hefty benefits from this type of variant. For one, '''social time in the evening''' is secured, because sleep time is not as early as the standard version. For another, the '''wake gap between 2 cores can be smaller''' than the original version, because of a potentially higher SWS pressure that will be resolved in the second core sleep. This setup would also benefit those who can wake up at later hours in the evening with a shifted work schedule to late morning or later. A somewhat short sleeper would even benefit from this variant more - not only is sleep time reduced somewhat, but all the access to evening events like other monophasic individuals and an uninterrupted flow of daytime commitments, without needing any naps. Adaptation to this variant is expected to be very difficult, which is one important note to bear in mind.

===Extension/Non-reducing===

The slight difference between Segmented-extended and non-reducing Segmented is that the former can still contribute to some amount of sleep reduction (e.g, 9h monophasic sleeper), while the latter does not reduce any sleep (e.g, 4.5-4.5 core combo for 9h sleeper). Either variants, however, only report some success over the years. The '''non-reducing''' variant has achieved a lot of success since the preindustrial era, which brings up the point that segmented sleep can be a natural sleep pattern for humans. Nowadays, with the advent of blue light and certain difficulties in managing the schedule alongside social time and hassling evening hours, it is deemed a lot harder to adapt to either variant. Another downside of both variants is that the longer core sleeps plus the wake gap between 2 cores makes the second core end later than usual. This can then clash with morning commitments if one has to wake up earlier than expected.

A benefit from the non-reducing variant is that it potentially can allow for '''some flexibility''' of either core during adaptation, and naturally segmented sleepers can still adapt to the schedule if they habitually wake up during the night and simply go to bed when they are tired enough. One success from the non-reducing variant (~7h total sleep on average) has the first core being ~4.5h long consistently (3 full cycles) while the second core hovers around 2h on average (~1.5-2.5h depending on day). This suggests that non-reducing variants can still be utilized by short sleepers to achieve a very flexible Segmented scheduling with natural Segmented habits to great effects. For non-natural Segmented sleepers, it is still advisable to try to sleep at the same time everyday for each core sleep. Regardless, not reducing total sleep may make it more difficult to adapt, because of the overall lower sleep pressure than a reducing variant.

[[File:Segmented Siesta-hybrid.png|center|thumb|A Segmented that looks like Siesta sleep]]This variant has surprisingly recorded at least 2 successes over time up to date; one attempt was done in a winter, where photoperiod was short. The first core becomes a lot shorter than usual, being reduced all the way to only 1 cycle, while the second core is dramatically longer than usual to compensate for the first core. Similar ideas can apply to 2.5-4.5 core distribution or so. The idea behind this variant is to have a very long wake gap between each core so that the second core can still occupy a fair amount of REM peak hours while still giving out sufficient SWS.
