Translations:Siesta/6/en

However, unlike most standard scheduling where a core sleep would make use of a multiple of the 90m sleep cycle, the standard reducing Siesta (6.5h total) utilizes a 5h core, because last 30 m is likely to contain extra REM sleep. 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 90 m, so the 30 m may also help with waking up after completed sleep cycles.
