Similar to E1, Siesta sleep takes advantage of the circadian dip around early afternoon. Siesta is considered to have 2 core sleeps, a long one at night and a short one in the day. In contrast to E1, the day core contains 1 full cycle, which is much more restorative than a short nap. The longer daytime sleep also allows for a shortened nocturnal sleep. Usually, the wake gap from the end of the night core to the daytime core can be between 6-9 hours. | Similar to E1, Siesta sleep takes advantage of the circadian dip around early afternoon.

Based on the typical human sleep structure, it is expected that SWS would be almost, if not fully covered in the first 3 full cycles of sleep (4.5h). On [[monophasic]] sleep, the REM cycles are often longer than 90m, so the 30m may also help with waking up after completed sleep cycles. | ||

Over time, waking up will become refreshing. The daytime core is usually reported to be less challenging to manage. However, for those unaccustomed to sleeping this long in the day, it could require learning and adjustment. | ||

Over the years, Siesta has reported great success, with the majority being with the non-reduced version. However, the standard reducing version has less success, due to the need of an adaptation to reduced sleep. Overall, the adaptation is relatively mild. It could be easier than E1 in some cases. With good time management and a functional alarm setup, most individuals should be able to adapt to the reducing Siesta version. | |||

Siesta sleep | Siesta sleep is overall a popular schedule, though it is significantly less popular than E1. First, managing a daytime core can be difficult, in comparison to the 20 minute nap on E1. However, recent trends of working from home or flexible school/work hours are making Siesta achievable for many. Another issue is that food time needs to be scheduled either right after the day core, or a few hours before it to ensure its quality. However, there is more leeway in scheduling meals with the daytime core on [[#Variants|extended]] versions, as the total sleep time is higher. After adaptation, the whole schedule can become flexible by flexing one or both core sleeps with small increments. | ||
Siesta (especially extended) is often done by athletes who perform intense exercises. Roger Federer and Usain Bolt are two of the many athletes who are known to habitually take a long sleep in the day. The day core provides recovery after an intense workout session, granting extra sleep time to meet the increased SWS requirement. It has been shown that after an endurance training session, SWS pressure rises and a daytime core allows SWS to be gained<ref>https://pubmed.ncbi.nlm.nih.gov/20308699/</ref>. The occurrence of SWS in the long siesta is said to release the growth hormone (GH), which regulates glucose levels and glycogen storage, which often become depleted under intense exercise sessions. | |||

Humans generally sleep more when severely sick, and often in a way resembling extended variants of Siesta, where both core sleeps are much longer than usual to allow for cognitive and physical recovery from sickness. | ||

Over the years, | Over the years, many Siesta sleepers have adapted to non-standard variants, including alternative reducing ones. The timing of the core sleeps also reported mixed results. Beginners should also look through the differences in the alternate scheduling variations before choosing the desired one to attempt. | ||

Over the years there | Over the years there a few successful attempts with this variant. The main idea behind this setup is to allow a longer wake gap in the day to suit 9-to-5 jobs. A sleeper would have a core at night, go to work, and then a long sleep block to rejuvenate after work. The advantages of this schedule includes time awake in the evening and night hours. For this reason, this variant can accomodate for many lifestyles. | ||
Despite the advantages, adaptations to this variant are | Despite the advantages, adaptations to this variant are known to be harder than the default version, because shifting the main sleep away from the SWS peak will require management of food, exercise and lighting to ensure a sufficient amount of SWS. (See also: [[dark period]]) Those with lower SWS requirements will likely find this easier. The short core is pushed much later into the afternoon and early evening. This core may start as late as 19:30. Even so, however, it may be still socially intrusive. | ||

Another great boon of non-reducing version is that sleepers do not have to be confined to a specific duration of daytime core length, as long as it's no shorter than ~50m (to differentiate with E1). and can be as long as ~2h. Thus, non-reducing Siesta has a lot of flexibility in scheduling, and heavily favors natural wakes (e.g, 60m daytime core one day, and ~80-90m core the next day). It is also not a requirement to sleep at the exact same hours everyday for both sleeps even when adapting (though consistency of sleep times is great). The goal is to ensure there is no sleep reduction from monophasic baseline to get as much productivity during the day as possible (for events or circumstances that require sharp decision-making and/or focus like examinations). | Another great boon of non-reducing version is that sleepers do not have to be confined to a specific duration of daytime core length, as long as it's no shorter than ~50m (to differentiate with E1). and can be as long as ~2h.
