It used to shift forward slightly every day, and sometimes invert &#8211; and sometimes I had big sudden shifts in my sleep rhythm. I also used to often wake up around 3 or 4 am. At one point I just gave up with trying to have 1 long sleep, and would do some reading in the middle of my sleep for an hour or two and that improved my sleep. <\/p>\n\n\n\n<p>I think it 2021 when I read about polyphasic sleep and I did a rather strict period of siesta-ext (6h30m+1h20m) for about half a year. The adaptation took a while, but afterwards this was the best sleep consistency and quality I&#8217;ve ever had. This schedule is a little reducing for me, with about 8 hours of sleep where my natural monophasic sleep duration is closer to 9 hours on average.<\/p>\n\n\n\n<p>I still try to stick to the siesta-ext schedule as much as possible, but I&#8217;m not strict with it at all any more. It can be hard to fit the afternoon &#8220;core&#8221; in and I&#8217;ve been moving towards a much longer night core. I&#8217;ve tried to do shorter naps when I can&#8217;t do a full afternoon core, but I still only manage an afternoon sleep just a few times per week. Lately, my sleep time has been shifting forward again too &#8211; I have flexible work times but now it&#8217;s getting a little out of hand.<br><br>I&#8217;m thinking of being a little stricter for a while again, to get to a <a href=\"https:\/\/www.polyphasic.net\/non-reducing-polyphasic-schedules\/#biphasic-x\">Biphasic-X<\/a> schedule where I do sleep twice <strong>every<\/strong> day. This schedule is very flexible, in that the night core can shift a bit, and the daytime nap can be anything from 10-90m in the afternoon. <\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"600\" src=\"https:\/\/invar.nl\/projects\/wp-content\/uploads\/2024\/01\/Biphasic-X.png\" alt=\"\" class=\"wp-image-293\" style=\"width:319px;height:auto\" srcset=\"https:\/\/invar.nl\/projects\/wp-content\/uploads\/2024\/01\/Biphasic-X.png 600w, https:\/\/invar.nl\/projects\/wp-content\/uploads\/2024\/01\/Biphasic-X-300x300.png 300w, https:\/\/invar.nl\/projects\/wp-content\/uploads\/2024\/01\/Biphasic-X-150x150.png 150w, https:\/\/invar.nl\/projects\/wp-content\/uploads\/2024\/01\/Biphasic-X-210x210.png 210w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<p>I think it would be good for me to stick to the following for a while:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Strict bed time; always go to bed at 00:00.
